Monitor starts blinking and then loses signal after startup

Q: Monitor starts blinking and then loses signal after startup

Hi everyone!

As you probably can tell I am new here. I really don't know very much about computers except the basics.

I just bought a new system from someone off Craigslist. I know it was probably a mistake but I am crossing my fingers that it wasn't. The guy seemed petty decent and let me play with it at his house and check it all out. It is a Sony Vaio desktop and I don't know much about it except that it is way nicer than my junk box from the year 2000. The specs that he gave me are:
Sony Vaio
Intel Pentium 4 CPU 3.6GHz
ATI Radeon X800 XT Platinum Edition graphics card
Windows XP Media Center Edition SP3
200 GB hard drive
DVD burner
Internal TV Tuner
Dual DVI-D monitor inputs
5.1 Channel audio card
22" Samsung LCD monitor
Wireless keyboard and mouse
Remote control (for using Windows media features ie windows media player or for use as a DVR)

Now, having said all that I am now having a major issue. It might be pretty simple but for someone like me it is driving me nuts. Everything worked fine at his house. No problems what so ever. I didn't hook it all up right away when I got home because it was very, very dirty and I wanted to clean it off. I used a whole can of monitor wipes to clean everything down. I was very careful about where I cleaned and how. So it sat for 24 hours without being connected. I plugged it in last night and everything worked fine. I went into "Add Remove Programs" and removed Google Chrome as I am a Firefox girl. I noticed that the add/remove list wasn't even a quarter of what the start menu showed though. Then I went in to rename the PC since it had his name and it asked me for a restart so I did just that.

Upon the startup, everything seemed fine. Then once windows completely loaded and I was ready to check out the rest of the programs the monitor started blinking. It went black, then came back up. It got faster and then stayed black longer. I shut it all down, checked the cables and then started it back up. Windows loaded and then immediately it did the same thing. This time, after it blinked a bit it went totally black and had a white box at the top that said "Analog" then flipped to "Digital" back and forth. When I unplugged the monitor from the back of the tower I got the normal "check signal" box on the monitor. So I shut down again and checked the cables again. I even flipped the cables, checked the power cables because the guy that sold it to me suggested to keep them separate. Nothing solves the problem. What is really driving me nuts is the fact that it was absolutely fine at his house. None of this happened and he told me that he had done a system restore to remove his personal thing but there was absolutely no problems with the monitor.

Does this sound at all familiar to anyone and is there an easy solution to fixing this probem. I have a computer guy that I can call but I just lost my job and since I already spent $450 on this computer I want to try and conserve my pennies. Please help me!

I turned on my computer, but forgot the monitor cable was disconnected. So I connected it. Screen stayed blank (black) (so much for plug and play, darn).
I hit the keys that I thought would cause a Windows restart, but it didn't work. Hit ESC a few times, and then some more Alt+F4 and arrow keys and enter and so forth, but nothing worked. So I held the "On" switch pressed until the computer turned off.
Waited a minute, then turned puter back on. Got the blue "Windows wasn't shut down correctly so must check everything" screen, everything checked out ok, Windows started to load, I saw the mostly-black screen with the big Windows logo, but just before it would normally switch to the blue screen with the horizintal animation, my monitor announced it wasn't getting a signal and went blank. Turned computer off, turned it on again, got the exact same result. I can stop the boot up and open the BIOS setup, but I have no idea whether that is going to be of any use to me.
I've seen similar problems described, but one said "I fixed it somehow" and another mentioned installing drivers, which I don't know how to do (what drivers, where, and to where?) without Windows running. (Sorry I'm a little clueless.)
So far I have not opened the computer, and I have double (and triple) checked the cables that everything is connected.
Any ideas? I'm Desparate!!

A:Monitor loses signal when Windows starts up

You said you double checked the cables, but double-double check that you don't have TWO video cards or two plugs on the video card. Such as having onboard video and AGP. If you have two video cards, try the other one.

Otherwise, to rule out a driver issue, can you get into Safe Mode? To get here, press F8 on your keyboard BEFORE you ever see any Windows logos. You can just press F8 once every second as the system boots if you like, to make sure you don't miss it.
You should get a menu, use the arrow keys to choose Safe Mode.
If that works fine, then it's a driver problem. If it still doesn't work, or the monitor cuts off even before this, then it could be a video problem instead I suppose.

And you might already know, but the system can still be working fine even though you don't see anything. Is it still churning away on the hard drive in the background? Do you hear your startup windows sound (if you have one). Does it sound and feel like it's booting normal even without the video? Or does it seem like the system just halts?

That aught to get us started.

I just updated the drivers to my ATI Radeon x1600 video card to the newest version. Once I rebooted everything went as normal, the computer booted up and started loading windows. Once windows took over the monitor went black. The light then came back on with the "No Signal" text and went back off.

I was updating at the request of Steam. Any ideas? I can get into Safe mode no problem.

I am going to try to make my issue clear along with what I've troubleshooted...
My Hardware

CPU: AMD X4 FX 4100 3.6GHz
GPU: Sapphire HD 7870 2GB DDR5
RAM: 8GB DDR 3 Corsair Vengeance 1600MHz (2 ram sticks)
PSU: 600 Watt Corsair Gaming edition
Motherboard: Gigabyte GA-990XA
HDD: 1TB Seagate Sata 3

My Issue

This issue usually happens when in any game BUT I have seen it happen once while just browsing online. When in the game application, my monitor will lose signal... I have tried multiple monitors with different connectors (HDMI, VGA etc.)

I haven't noticed a consistent time that the issue happens.

What I THINK I've ruled out

-CPU and GPU heat doesn't seem to be a problem according to CPU-Z, GPU-Z, Speed fan,etc
-Made sure dual channel RAM (2 sticks) is in proper slots
-Took 1 stick of ram out, and vice versa...The problem still happened
-Used different monitors and connectors. The problem still happened
What should I do to resolve this. The parts have been purchased new about one month ago. Is there an issue with compatibility between my hardware or what piece of hardware is likely causing the issue and what tools should I use to verify it?

I've looked around online but I haven't found much luck.

A:Monitor Loses Signal...

Hey Sullivan Welcome to TSG. Hope you get some help and provide help to others when you get the opportunity. Thats how the community works!

At this point, the easyist next step, I would look at updating or reinstalling drivers for the video card. I notice you don't list a video card??

Often the problem with gaming computers is the video card gets hot and shuts down. Speed fan is a tool but doesn't get exact temp of video card. If problem persist try running with the case open and or adding external fan.

While I play a video game, FPS in game start dropping and the monitor loses signal, but the PC is still working. Today I tried the thingy with Capslock and after I pressed it two times, my PC stopped. After I turned it back on it booted, but a black screen appeared and not the logo and after that it rebooted itself and now it's working. I can't play video games at all anymore.

My CPU is i5-3450 3.10 and graphic card GTX 650.

I had this problem even on previous version of windows.

I can watch movies and videos on chrome fine, but when I play games the hell unleashes.

I have what I think is a monitor problem but could be a videocard problem. I'm still doing some testings.

It used to be, every now and then my monitor would lose signal and I would have to restart my PC. Two days ago, the problem got serious and the monitor displays a message telling me the frequency was out of range. Rebooting doesn't fix it. The horizontal frequency was something like 0.2, and the vertical frequency was 345, but the numbers change with each reboot.

The monitor shows video fine up until Windows starts to load and the monitor just goes blank and the LED turns yellow. When I go to the bios screen, the monitor also loses signal within a couple of seconds. I don't know if it's a nvidia driver problem, but I don't think the driver is loaded yet at that point so it can't be.

My best guess is the monitor is malfunctioning or the videocard.

Any ideas? My monitor is a 19" Envision 980e and videocard is a Leadtek A250 LE TD, My ViVo edition. Both are about 1 years old.

It can't be drivers if it malfunctions in the BIOS too.

Most obvious thing to do is to try another monitor and/or video card.

Ok. Today I got a widescreen TV, I unplugged my DVI from my monitor to plug it into the TV to see how it looked. Now when I boot my PC it will show the BIOS post and the windows load screen, then it will show a flash of my desktop and my monitor says "no signal". All the sounds of windows booting up still come out of the speakers during the "no Signal" part.
Now heres the funny thing. If I boot into safe mode it works fine. Matter of fact im typing this post on it now. Any ideas to why this is happening when I boot in normal mode. My vid card is an XFX 8800GT(256mb) if that helps.

The CPU is clearly running, since the audio remains perfect. The only way to re-connect the signal is by re-starting the computer. Interestingly, it seems to happen only when he is playing these games (more than one kind), which he used to play for hours in this same system. Any clues?

I'm hoping someone has an idea what my problem is as I've seen this problem on other forums so maybe I can help someone else.

I've had an AMD Athlon 2800 + Asus A7n8x-e motherboard setup for about two years now that was running windows 2000 with a geforce 4 graphics card and a gig of ram. 430 watt power supply. A few months ago I bought a copy of XP and upgraded. Still, several months of smooth sailing and lots of World of Warcraft playing. About two weeks ago the monitor started losing the signal. I would start the computer and right after xp was going to load and have me log in the monitor would go to standby, as if it lost the signal. Over the course of two weeks it started happening more often. Sometimes I could get logged in and have a whole day of usage out of the computer including playing games or other times I'd have to reset it fifteen times before it would let me use it for hours. Over the last couple of days the loss of signal began happening while playing games, or web browsing. A little more random than at the xp startup point. I swapped monitors, bought a new graphics card and I'm still dealing with the issue. Today I was getting a one in ten chance that the computer would get to windows without losing the monitor signal. Then, cross my fingers, would get some gaming time. Today I gave up and waited for my new vid card to show up. After installing the Geforce 6800gs, and reinstalling drivers for the MBoard, direct x, vid card, bios,... Read more

Yes you need a bigger and better PSU. 430W is never a full 430, it's more like 300 with the generic/cheapys. It's prob 2 yrs old too and ready to die. Replace it before you damage your new 6800GT.

You said you had to unplug 2 fans to get it to boot, that says it all right there.

3 days ago, I started to have this signal loss+reboot problem.

First day, it occured once at 5:55am
Second day, it occured once at 6:00am
Today, which is the third, it occured at 8:00pm and 2:00am

Describing what happened in details..
Basically, my monitor would randomly lose signal, but the background keeps going (such as MSN and music) , then it would automatically restart after few seconds.

I thought the problem was overheat caused by graphic card, but that doesn't seem to be the case.

Some information about my system:
Motherboard: P5K-E

My computer has been doing this for awhile, it works fine, I can watch videos on it and everything, then I go play a game (Call of Duty 4 on max graphics) then after a minute or two my monitor would go blank (Blue in this case since its HDMI) and lose the signal to the graphics card, The connector isn't loose, nor is power and I must reboot to get the signal back.

I have upgraded the computer with this graphics card, I did uninstall old drivers but maybe not fully.

Another perhaps unrelated problem is that whenever I restart, it no longer detects my graphics card, resolution: 800x600, 4-bit, I must uninstall all my drivers, then reinstall them and it fixes the problem

Its not overheated
Power SHOULD be sufficient.

I am not sure where to put this post. Sorry if i make any mistakes; English is not my first language.
My PC (Dell Alienware x51 R2) has been reset two days ago.

The other day I tried to play Team Fortress 2, but the screen turns black and says: "No Signal Detected" After the restart (signal is available again) I type in my passwort for my Microsoft account; the screen loses signal again. The same thing happens on the second restart. Only on the third restart the monitor keeps signal.

It does not even have to be Team Fortress 2. The same happens after playing Hearthstone for a quarter-hour or sometimes when I am watching Youtube Videos.

So the cables can not be the problem because they do not get touched at any time. Maybe it is the videocard (?) because the signal loss always happens when it sort of gets stressed too much. But the ePSA test (an option in the boot menu which stress tests all hardware) says everything is fine.

This started to happen about a month ago and has been getting progressively more frequent. Nothing has changed on my system, no new hardware. After the first time it was a couple of weeks until it happened again, then a week, then a few days, now it's just been two days apart.

With no warning, my monitor with go dark and pop up a no signal message. At first I thought it was the video card going bad, but today I realized that the keyboard was locking up as well. I was using a chat program with push to talk, and talking with friends at the time, and I asked if they could hear me after the monitor lost signal. They could not, and that is when I realized my keyboard was locking up as well, I couldn't turn on caps lock, etc.

This problem has showed up in the last few days and it's becoming quite annoying. Basically, after a while of gaming (usually about 30 minutes of League of Legends, though it happens with other games as well), my monitor will just go black and the "on" light will start blinking, the same as when I turn the monitor on without turning the pc on. However, the pc doesn't restart (I still hear the fans, etc) and I can still hear the sounds from the game, though I don't believe it responds to my keyboard inputs.

Any help would be highly appreciated.

Start by posting your temps and voltages; specifically the cpu temp, system temp, 12V, 5V, and 3.3V values. The info is available in the bios; read your mb manual for a detailed description of bios options/menus.

Next you need to list your exact system specs; ie exact mb installed, exact ram installed, exact pw supply installed, etc, etc. Note 4ig of ram does not really tell use much; 4gig of corsair xxx123 ram tells us a LOT more.

When I turn on my PC, everything starts as it should, until the Windows XP boot screen appears (you know, the one with the Windows XP logo and the left-to-right "loading" bar moving below it against a black screen). Unfortunately, just as the Windows "welcome" music plays over the speakers, the screen goes dark and my monitor posts a "no signal detected" message.

I am almost certain the problem has to with my video card. While my web research revealed several recommendations to start up in Safe Mode, I have tried holding and tapping F8 without any success -- I never get to start up in Safe Mode before the monitor goes blank. I have also tried a different monitor, but the result is the same, and my monitor works fine with my girlfriend's PC. ARRRRGH! This is so frustrating!

How do I fix this? I do have my XP boot disk. Will I need to purchase a new video card? If so, will installing this be complicated?

My PC is about 7 years old and is not worth much.... :-(

Good day everyone,
I have an ATI 2900XT 512mb that has worked just fine on my PC until a few days, out of nothing it stopped sending the monitor signal. After disconnecting power cable from the pc and replugging it seemed to work again but lately it stopped sending the signal for good. I took out the video card, put it back in and it worked for just a few minutes. I've tried booting a few times and sometimes I get the monitor signal for just a few minutes, most of the time nothing at all and the mobo has error beeped a few times.

I've also noticed that when I boot pc and the monitor has no video signal the pc hasn't beeped, it's weird because it used to work fine and now if it does is just for less than 2 minutes.

I have a DFI P965 mobo and a Rosewill RP500-2 power supply.
Any clues on what could be the failure?

Now before you all link me to other places with the same problem, mine is a little different.

I turn on the computer, goes past the bios screen as normal, does the windows loading screen as normal, then the screen goes black and the "No Signal" message is displayed.

Now, here is why it is different. I type in my password and press enter, without being able to see and wait for the logon sound to play, then if I unplug monitors cable, I hear the noise of windows telling me a device has been disconnected, I plug it back in again the device connection noise then plays and low and behold, there is the desktop.

I have been running Windows 7 build 7100 for roughly about three weeks until this started happening about one week ago.

MONITOR: ViewSonic VX1932wm
GPU: Sapphire HD4850 512mb


Also, I have noticed too after logging, randomly Aero will disable itself, I have to open the 'Personalize' option and run the troubleshoot to get it to fix itself again.

I assume this is the correct section, as I am experiencing visual issues. Apologies if this is not the correct section.

Any suggestions are much appreciated. Thanks.

A:Monitor loses signal before logon screen

This could be down to a number of issues. In no particular order, these are graphics and/or monitor drivers, a faulty graphics card, faulty monitor cable. If your graphics card has another port, try to connect to that one. Do you use a DVI-VGA adapter plug? If so, it is possible that this has become damaged (I've had this issue with mine). Fortunately, they are cheap and easily replaced. If your card requires additional power, ensure that this is connected and that the card is correctly seated.

I've read a lot of different material around the web and various boards about variations of this problem, and am still stumped. I'm running a Dell XPS 400 dual core, with a nvidia geforce 7900gs, 2gigs of ram, etc.

One day, the monitor started to flash in and out, and after about fifteen minutes of this it finally went black and the monitor's yellow 'no signal' light came on. The computer continued to function otherwise: music continued to play and be changable, keyboard inputs continued to work, etc. On reboot the signal returned, but the problem repeated, and eventually, it took up to ten reboots until signal would return. Sometimes it would take several hours of waiting before the signal would come back. Strangely enough, after a few weeks, the problem went away for four or five months and came back, then went away for a few months, and now is back again. This happens in both 3D games and just general XP browsing.

Over the course of the problem, I have replaced the stock power supply with an antec 500watt. I replaced the original card, an ATI all in wonder x1800xl with the geforce 7900gs. The old ATI card is working just fine in a friends computer. I've tried flashing the BIOS to the newest version on Dell's website, still no luck. I have also swapped out monitors, no luck again.

What else can I do? Is it time to buy a new motherboard? Do I need to test the RAM? Does God just hate me? Any help is appreciated.

Hi guys, this problem just started happening today. I turned my computer on and started playing Dead Space. 5 minutes into my gaming session, my monitor goes blank and says "No Signal" (as if my computer was turned off). I had my headphones on and could still hear the game sounds. After a few seconds, the game sounds started to stutter and didn't stop. I turned my monitor off using the power button, waited a few seconds and turned it back on and it still said the same thing. I had to turn my computer off manually using the power button after that since I couldn't do anything. I waited a minute and turned it back on. I then tried to play Bad Company 2 and the same thing happened.

I run EVGA precision to control my GPU fan speed and monitor the temp. While gaming, it's usually at about 60-70 degrees Celsius, so I don't think it's a temp problem.

I'm not very computer literate, so I really don't know what to do at this point... so, I'm turning to you guys for help. I hope someone out there is able to help me.

Hello. I am new here so please go easy on me. I have an HP media center m7287c. It has windows xp Home. Here is my problem. Just recently my computer will not boot completely and/or my monitor shuts off. I have tested my monitor with 2 other pc's and there is nothing wrong with the monitor itself. But when I turn on the Computer the montitor receives a good signal. I can see the blue HP screen that says F11 for system recovery, F1 for setup, etc. It then goes into the "load" screen where it says Windows XP with the little moving bars below it. After it is done loading... the light on my monitor goes from GREEN TO ORANGE and the monitor "goes to sleep" and turns black. Obviously its not getting a signal and I don't know why. Meanwhile the computer doesn't reboot, it stays on, the temperatures are all normal. I have not done anything to it in terms of hardware. It is "stock" and has an integrated monitor input rather than an AGP or PCI video card. What might be wrong, what can I do...and HOW? Thank you in advance.

I boot into safe mode and after a few minutes my monitor loses signal as if its unplugged EVERY TIME.
if I hard restart the computer (front panel restart button) it beeps oddly on start up and I have no signal to my monitor.
but if I shut down the computer totally it will be fine once I start it again (unless I go into safe mode.. then it does the same thing)

this is awful since I need to get into safe mode to run scans and such and can't do anything that takes longer than a minute or two.

My problem is if I'm playing a game that uses 3d graphics my monitor will lose signal. But now I just noticed if I run adobe photoshop cs2 for about 20 mins it'll do it also. So what do you think my problem is?
Ok I have a emachines t2625 here are the specs and I have a ATI Radeon 9200 128MB AGP card in with a Maya 7.1 Sound Card. I've updated all my drivers and everything. I'm using Omega video drivers's also.

A:Monitor loses signal as certin times

you say it "loses signal"... by that do you mean the computer remains on and you can still use it but cant see anything?

the first and most obvious thing to check would be the monitor cable, make sure that it's clean and not lose. wiggle the cable around to see if it "loses signal" again.

do you have another monitor that you could try?

also, make sure that you aren't setting the games video settings higher than your video card and monitor can handle.

It sounds to me like your power supply may be going bad. emachines are known for their low-quality motherboards and power supplies. it could be either one, but my guess is the power supply.

I have a dual monitor setup on my PC. Today, when I boot it up, the main monitor displayed all theboot information and startup stuff, however, when the system SHOULD have gotten to the user login screen, the main montor came up with "no signal." The secondary monitor at this time will still show my mouse moving around on it, and I'm able to move the mouse over to the main monitor but I can't see anything.

I've gone through a few basic manuevers to see what was wrong. I booted in safe mode and logged in to my mai account and attempted to change the other monitor to the main one; However, Safe Mode does not appear to supoort multi-monitor and I couldn't change this. After that, I attempted to VNC into my computer with the notebook I'm on now. When I came to the login dialogue box, the only account I could log into was the invisible "Administrator" account. My main account, as well as a temporary account I created for testing, both came up with an error "Cannot access due to user restrictions." My theory is that because all of the accounts which are actually visible on the login screen seem to not be working, the login is bugging and not outputting anything to my main monitor (since I have verified both monitors and connections to be working properly).

I'm stumped as to this problem; any help would be greatly appreciated.

Alright, my stupid computer is at it again...
It's happened twice today, when I finally thought it was runnign well. In the middle of a game of the UT3 demo, when exiting out of it the monitor shuts off(comp is still running) and a minute or so later my g15 displays the same exact settings(cpu and ram) so I assume it's frozen. I find it weird though, that the monitor shuts off the signal first. When trying to open explorer it did this, but the monitor came back on for a brief second and it was acting like it was trying to open back up. I could see a glimpse of IE opening up, but then the monitor lost signal and the comp froze.

Any ideas? This is a 4 day old computer.

A:monitor loses signal while computer randomly wants to shut down

yeah try this, while the computer is running correctly, press your power button and make sure it will shutdown as if you went to Start, Turn off Computer, Shutdown. Then when the computer does it again and you can't see anything on the monitor, hit the power button and just see if the computer shuts itself off like it should. This will tell you if it is the monitor/video card, versus the pc itself freezing up.

Hey guys.

So, everything was working just fine until this very morning. No headaches whatsoever.

So, this morning I turn on my monitor and receive a "HDMI No Signal" from my monitor. Thing is that, 8 hours prior, it was working just fine. So, here's what I've done.

* Monitor was connected to a self-powered HDMI switch. Connected directly instead. No signal.
* Electric reset. Nope
* DVI. Nope.

Until, I bit the bullet and pressed the reset button while my monitor was connected in DVI. Lo and behold, signal! HDMI worked too. So, after an hour no problem, I had to attend some business in town then visited my father. When I came back, my monitor... had no signal once again.

So, I pulled off an old 24" monitor (1920x1200) off my closet that was going bad on one side but was still working, we could still see something. Connected DVI on it (no HDMI). No signal. So, I put my main monitor back in place through HDMI and reset. Voil?, once again.

So, checking my temps now, it's definitely not overheating. My graphic card idles at 36oC and my CPU is ~45oC (it always does a little something all the time - 5-10% use).

I will be trying to update my GPU drivers although I don't have a lot of faith in that and I can't really test my GPU in other computers.

I've read a lot of different material around the web and various boards about variations of this problem, and am still stumped. I'm running a Dell XPS 400 dual core, with a nvidia geforce 7900gs, 2gigs of ram, etc.

One day, the monitor started to flash in and out, and after about fifteen minutes of this it finally went black and the monitor's yellow 'no signal' light came on. The computer continued to function otherwise: music continued to play and be changable, keyboard inputs continued to work, etc. On reboot the signal returned, but the problem repeated, and eventually, it took up to ten reboots until signal would return. Sometimes it would take several hours of waiting before the signal would come back. Strangely enough, after a few weeks, the problem went away for four or five months and came back, then went away for a few months, and now is back again. This happens in both 3D games and just general XP browsing.

Over the course of trying to solve the problem and from reading various forums, I have replaced the stock power supply with an antec 500watt. I replaced the original card, an ATI all in wonder x1800xl with a geforce 7900gs. The old ATI card is working just fine in a friends computer. I've tried flashing the BIOS to the newest version on Dell's website, still no luck. I have also swapped out monitors, no luck again.

A:Monitor flashes, loses signal, computer continues to run

If you're NOT using the same video cable with both monitors, then your motherboard's AGP/PCIe (whichever it is) slot/controller is probably bad. This would affect the video and nothing else. What you're describing is definitely a hardware problem. So, yes, I'd say it's time for a new board.

I bought this pc from HP in 2010. It ran perfectly until i got a virus a few months back and lost both hard drives due to corruption and had to start from scratch. I had a local computer shop install new drives & reinstall Windows as I am not that computer savvy. Everything is now up and running fine with the exception of this issue. In a nut shell the issue is whenever there is a delay in the pc rebooting due to software installation or windows update the monitor will lose signal usually right after the windows starting screen, but before the log-on screen appears. clicking the mouse or keyboard does not bring back the signal and the monitor just goes to sleep. I have to manually power the pc down at that point because i cannot see what it's doing. Just pressing the power button once on the pc does not always power it off at this point. Sometimes I even lose the montor signal after I log in and the desktop is loading for a few seconds the monitor will lose signal and go to sleep. If it's a straight boot-up or restart with no configuration going on in the background it seems to be fine and i can log-in normally. If I get into the desktop without losing signal then I never encounter any other signal loss or monitor issues until the next required reboot. Another thing it has done randomly a few times is if I put the pc into sleep mode, when... Read more

Hey all:

I have hit upon a really annoying problem. I just did a complete reformat of my computer and I have been trying to get my video drivers to work.

Here's my problem: The card works, I get video and everything, and I can boot to Windows XP fine.

Then I install my Nvidia drivers and restart the computer, like it says, and as soon as the computer finishes loading Windows, just when it should go to the welcome screen, the monitor goes black and then says it has no signal. If I restart in safe mode and then uninstall the drivers, I can boot normally again. It functions on the basic Microsoft Driver: (GeForce 4 Ti-4400 (Microsoft Corporation)), but as soon as I try and install drivers from Nvidia, the problem happens again.

I have tried the newest drivers and two older drivers.

I also have tried a friend's ATI Radeon 9800 SE card, and that seems to work, except that their Catalyst program locks up my computer when it tries to detect the optimal GPU settings. I am wondering if the two issues could be related.

Anyway, if anyone could provide any help here, that would be excellent!

It sounds like you missed chipset/agp chipset drivers when you reformatted your system. These wont come into play until accelerated AGP graphics drivers are attempted to be installed/initialized.

What mainboard do you have? You should obtain the newest motherboard chipset drivers and then retry your driver installation woes.

The Short Version:
Windows vista boots up and loses connection with the monitor. Fixing this means disconnecting from the video card, and reconnected, while jiggling the mouse. It then turns on and works in low resolution mode, with no option to expand further than 1024x768. Tasks are 4x as slow (on average) to complete. Every new boot/alteration of driver files and functions resets the monitor. If you believe this problem is within your ability, More information on the event is below.

Full Incident:
So I brought over 2 pc games of mine for a friend without internet for the week.
San andreas, and Trackmania United. I loaded San andreas onto his bran new Vista gaming rig, and booted it. It played well, but the textures were off...While booting up trackmania, EVERYTHING slowed down, then stopped, then froze. I rebooted once, and then a subsiquent hour of booting and rebooting. I went into safe mode (which works) and did a system restore to earlier that day. When vista booted up, the signal to the monitor was lost. We could hear vista working with the bells and whisles going off, but we couldn't see anything. I found out that if you unplug, and then re-plug the monitor and then jiggle the mouse, the monitor would reconnect.
NOW vista is running as if there were no video drivers for it, and in that low resolution mode, most programs, and some games (as benchmarks). It was running WELL below the expected behavior. His computer is quite top of the line.

I've had a series of problems with my computer lately.

First of all, sometimes while playing games with high graphics, the monitor will lose signal and there seems nothing I can do to fix it besides restart. Strangely enough, after dusting the computer out and pulling out and putting in the RAM, I haven't had this problem anymore, but I am worried it will come back, and I wonder what the cause of the signal loss was.

Also, the keyboard and mouse sometimes both die on me, no matter what I am doing on the computer. The monitor will still work after this happens.

Also, I've just noticed that my computer says I only have 6GB ram, when in fact I have 8GB installed. Not sure if that's related.

Any ideas on the cause of these problems, and if they are related?

About a week ago I was playing Fallout:NV when all of a sudden my monitor went black (I can't recall if the game was still running or not). I restarted my computer and all seemed fine; so I started the game up only to have it go dark again a few seconds later. Frustrated and tired, I figured I'd leave it until the next day to try and solve it. Only the next time I powered my computer up, I got the "No signal to monitor" and an abnormal post beep but I could hear Windows XP starting fine. I checked all the cord and wire connections and reseated my msi 8800gts, none of which helped. I assumed my gts had bit the dust, so I went and bought a pny 9800gt that night and after installing it, everything worked fine. Normal post beep, monitor worked, and no crashing in Fallout for the few minutes I played.

Ofcourse though, I was disappointed in buying something that was marginally of lesser quality then my last card, so I went back to BestBuy the next day and returned the card for a Galaxy GTX 460 (786mb). After installing it and powering up, I was greeted by the "No signal to monitor" message again but I could still hear Windows start. I checked the connections again and reseated the card like before. This time though, it entered a power up and down loop for a few seconds until it would finally abnormally beep.

Video Card - 1.25Gb Nvidia Geforce GTX 570
Ram - 8gb DDR III
Power Supply - Thermaltake Toughpower 750w
Motherboard - Asus P8Z68-V Pro

I have had my PC now for a good several months, and had no problems with it. For the past couple of days my PC has been just crashing & restarting itself constantly, and I have no idea why.

Now though, it will not even boot up properly. Basically, what happens is I turn the PC on and it starts to boot up. It then restarts itself around 5 seconds later, only to boot up again. It only seems to restart itself the once though for some reason.

The problem is, nothing is going to my monitor whatsoever. It just says "check cable signal" on the monitor, even though the PC seems to be on. I've tried the monitor on a different computer & it works fine, so I know it's not a problem with that.

I've tried taking out the RAM, Graphics Card, PSU and refitting them to see if anything was out of place, and I've also double checked to make sure if all the cables are properly plugged in, which they are.

I'm finding this extremely irritating, as I just can't find out what's wrong with it at all, it's just started happening all of a sudden.

I'd really appreciate some help with this, thank you.

I have a computer that was working perfectly and after using compressed air it won't give a signal to the monitor, the keyboard doesn't light up (I'm assuming no power to the mouse either), and there is no beep when I start it. Internet cable lights up when I connect it, and the speakers make a "pop" noise like its receiving signal fromt the sound card. I tested the monitor, RAM, and graphics card on another computer and they seem fine...Fans are running okay and I removed the little circular battery from the mother board for half an hour to drain it, but still nothing.

Does this sound like a motherboard problem? I have a K9N platinum and if you suggest it is this, can you recommend a new motherboard (as this doesn't seem to be easy to come by anymore)? Hopefully its not the hard drive...

Hi All, First Post Round these parts!

I have a problem with another computer that I'm hoping you kind people will be able to help me out with. I've searched the forums high and low but can't find an answer so here goes:

Basically, in an unrelated issue, my Widescreen LCD screen has been playing up lately with some odd scrambling coming up and I needed to check if it was either the monitor, cable or my graphics card playing up. I took the monitor downstairs to plug into the other computer in the house. The monitor still scrambled on this but when loading up it only got as far as the XP loading bar (this screen). This proved that it was my monitor at fault. But I was a bit concerned that it lost signal and wouldn't load the desktop.

There is only one account on the computer so it normally loads straight to the desktop. For some unknown reason, the other LCD screen (a normal resolution one - it runs on 1280x1024) that is normally used on the computer looses signal once the load up sequence gets past the XP loadup bar and the green light on the front switches to yellow. It's like there's no connection or something - its just the same as pulling the cable out of your graphics card - the screen goes blank.

Everything else works fine. I tried restarting with the sound on, and you can hear the little jingle as the desktop loads. With a bit of guesswork with the mouse, the computer obviously works perfectly fine otherwise as you can hear the HD worki... Read more

Hi All,

During final installation of windows the monitor kept losing signal. If I unplugged LCD from graphics card, and plugged in an old CRT, the picture was there.

After a minute I could unplug the CRT and put the LCD back on and it would work.

This happens when changing user, booting up (at Window?s login page) and often when installing software.

The graphics card was fine in XP, this has only happened since installing Win7, which was yesterday..

I have turned off any sleep and power saving settings in Windows. I have the latest Nvidia drivers for my GTX275.

Grateful for any help,

For at least a week now I've been having stability issues with my internet connection. It seems that every day, at least six or seven times a day, I'll lose my internet connection (ie: The "Cable" light on my modem goes out and I can't access the internet.) I've found that if I remove the AC adapter plug from the back of the modem, wait a few seconds and then put it back in, the modem will re-sync up and I get my connection back. I've also noticed that if I leave the computer for maybe two hours at the most, I'll come back and have lost my internet connection. I've tred searching the Cox FAQ databases to no avail. Just thought I'd post here before I start talking to Tech Support. Could it be the modem? The coaxial wire? Or is it something on Cox's side of the fence?

A friend of mine helped me hook it up and it ran fine until about 2 weeks ago. My PC's run on windows 98 and windows millenium.

Now, the USB Netgear adapter keeps losing it's signal after several hours when the computer is idle. I tried putting the netgear device in my start-up thinking that would keep it on, but it hasn't mattered. I can get the signal back right away if I disconnect the adapter from the USB cable. But then after a few hours, it loses the signal again. Nothing has changed with the computers except I had to replace a USB keyboard with an old style one for the wireless hooked up computer. Also, and I'm not sure this matters, as I have only one USB port on the PC, I had to buy a 4 to 1 USB adaptor when I bought a USB printer, but I have had that for a year now.

Can you help me?

I use the laptops bulitin NIC to reach the Internet, and then i added a usb wifi adapter to reach my security cameras.

Unfortunately after a few days the Connection to the Internet through the built in NIC is lost.

I have noticed a Solution that if I use a Proxy in the Webbrowser that , the Laptops NIC connection to the Internet returns.

Both Networks run fine.

So I need to ask how i can enter a Proxy from my own personal router to the Webrowser.

If i use the VPN Proxy, the internet slows down too much so i need to enter a Proxy that would be directly to my own router. Therefore no speed limits.

I guess i could create a reserved Ip for my laptop in my router settings and then enter that as my local proxy. But I would prefer a static ip and i dont want to have to enter that each time in the webbrowser network connection.

About a week ago my laptop started acting strange. I noticed when I brought my computer to my room (which is where i usually use my computer) it said that there were connections available where the signal bar is. Which is odd because it usually just auto connects. So i clicked on the signal bar and connected to my internet, but it lost the connection shortly after so I clicked connect again and it said windows was unable to connect to the router. Then shortly after that it said no connections were available. So i brought the computer to the computer to the family room ,where the router is, to check the router. It was nothing wrong with the router so I looked back at the computer and it was automatically connected to the internet with a five bar connection, but when i left the family room with the computer it immediately lost the signal. So i decided i should just stay in the family room. The next day the same problem occured and i went back to the family room to use the computer but i noticed the connection wasnt usually at five bars like it usually is wen im that close to the router but it was 4 bars or 3. The next day i went over my fathers house for the weekend, and when im over there i pretty much always have a five bar connection even though im not in the same room as the router because im 1 floor directly above the router.

Hi, I am having a very very annoying issue with my computer. I had recently re-installed microsoft windows, and this puts the total to about...7-8 times, in hopes that it was something I had done that made my computer act this way.

The problem is that during someform or another, and this is also assuming the computer starts up in the first place, at a random time the screen will lose video input, my PNY GeForce 9600 GT will go to high-rev, my Disk Drives will begin revving up, and I cant do anything. This forces me to hold down the power button, something I dread doing, and hoping it will fix itself....It is not a dirty computer as I spent two days with a can of air cleaning it.

This either happens during bootup, where the monitor doesnt even bother receiving input, or during normal usage, or more importantly, playing battlefield 2, the only game I had bothered to install completely.

This problem has happened before, namely with games like tabula rasa and battlefield 2, but usually very infrequently. However, I had recieved a 23" ACER LCD Widescreen monitor, and it is using the white digital video cord that it came with....the one that has the horizontal bar in the connection area. It has happened more often with it.

One problem I am concerned with is my power supply. I know the 9600 GT takes up a bit more power than normal, and my power supply unit didnt completely match the recommendation. I had been using a 19" standard dell monitor that didnt take ... Read more

During a recent storm, lightning struck very close to my house and we lost power immediately after the lightning strike. Once power was restored, my HP Pavilion a6000 would not re-start. The computer and all the peripherals were protected (I thought) by two surge protectors.

On closer inspection, I found that the green LED on the power supply was blinking. I disconnected all the connections coming from the power supply, and when I did, the green light went from blinking to steady on. I re-connected the leads one by one, and the light stayed on until I connected the 20 pin connection to the motherboard. As soon as I connected the 20 pin lead to the motherboard, the solid green LED went back to flashing.

I assume from the diagnostics that something on the motherboard was fried by the lightning? I know how to replace a power supply, but have never dealt with motherboard issues, so not sure how to proceed. The computer is only 6 months old and I would like to save it, but don't know what I might be looking as far as expense and time involved to repair.

Hi friends, I'm using Dell Studio 1558 and recently bought an original battery online and I dont know the authenticity of that battery. Also before changing the battery, I had a hard disk crash and changed a new hard disk.
Now at times, I'm getting amber and white light flashing. Its getting corrected if I restart the system.
Can anyone let me know the meaning of this flashing amber and white lighting?

A:Amber and White light blinking. What is the meaning of that signal?

" recently bought an original battery online and I dont know the authenticity of that battery "

It's a possibility the flashing amber/white light means battery is low and isn't being charge. I like to suggest you check the status of the battery and AC adapter in the BIOS.
1. Power off computer, and then make sure AC adapter is connected to computer well
2. Power on computer, quickly start tapping the F2 key continuously, you should be in the BIOS screen.

Under the main screen, look for the AC adapter type. If the adapter says None or Unknown then it's an issue with the adapter. Suggest you replace AC adapter.
Under the Advanced screen, look for Battery Health, it should say "This Battery Is Performing Normally". If there's any other message, it could mean that the battery is faulty and needs replacement.

Note: If you indeed need replacement, please get a new genuine Dell battery that comparable with your system.

I'm not very knowledgeable when it comes to computer, ah, specs (or finding information about the one I have)... so I don't have much for you to go on.

Computer is a Dell, with Windows XP Home Edition. Monitor is LCD.

A few days ago (around Wednesday morning) my monitor began to click on and off. The screen would flash black and the light, next to the on/off button, would flash from green (on) to yellow/orange (off). At first it wasn't that bad. When I switched pages on the internet, scrolled, or highlighted something on the page it would flash.
It steadily got worse, going from internet pages to flashing on and off right when I turned the computer on, all through the loading and welcome screens.
I thought maybe it was just the monitor, so I switched it out and hooked up my old hp pavilion mx70 monitor.

That monitor worked perfectly fine with my old tower, but when hooked up to my new one it... Erm, got 'static-y'. It looked like an old TV that had a VHS tape in the player, being re-wound. I know that sounds odd, but it was like spikes from the side of the screen surging inwards. I thought it was because the monitor was so much older than the tower. Soon the static got steadily worse, and I used it for about a day before it got to be too much.

I switched to Safe Mode with Networking on the hp monitor, to see what would happen, and it was fine! No static. Today, I switched back to my LCD monitor and put that into Safe Mode with Networking and no b... Read more

A:Solved: Monitor or Tower problem? Monitor is blinking on and off.

Video card is busted. When in safe mode, the video card's drivers are not loaded, so the card does not function at "full blast". It will not cause trouble because of that.
Dell model would help finding a replacement, but it can well be assumed that there's a PCI-E 16x slot for add-on graphics. This would be a cheap replacement in that case:

This is all an assumption on the most propable cause. The problem could also be your power supply or motherboard, but those are pretty unlikely.

If you could try the monitor on another PC, that would confirm the monitor is faulty. In any case if the monitor is bad and considering its age, it would be best to just replace it. It would not be worth fixing.

I was getting the odd "Page fault in non-paged area" BSOD about once a month. I also had another issue where the computer would hang on startups after the windows splash to a black screen with only my mouse cursor. This would cause me to hard reset. Due to Occam's razor I attributed both the BSODs and the inability for my computer to load on every other startup to the same error.

I googled this issue and noticed it was related to messed up ram. This prompted me to run memtest86 last week. Memtest86 returned dozens of errors after going through 4 passes. Because of this I RMA'd the RAM.

Today I installed the new RAM. I have not seen a "page fault in non paged area" bsod as of yet, but they usually took time to show up (>1 week of computer usage).

I have 2 problems with my computer, both of which require me to hold the power button down for 5 seconds to hard reboot (and I wait 30 seconds before turning it back on because I heard that was good somewhere...). My computer either:

A) randomly loses signal to the monitor, resulting in the monitor going to sleep while my computer is still on. When this happens, audio from iTunes continues to play normally, but I cannot pause it or control the volume which I can usually do from my keyboard. This leads me to believe that I have absolutely no control over my computer when my computer loses signal with the monitor. This can happen at any time... when I'm playing a videogame, browsing the internet, or when the computer is locked and I'm not using it at all.

B) randomly freezes. This locks up the computer completely and I am unable to move my mouse or control anything. I don't know if audio continues to play because this hasn't occurred while I've been listening to something on iTun... Read more

Hello everyone,
This is my first time posting here, so I ask that you please bear with me :) I am a freelance computer tech who works on people's PCs in my spare time. I am working on a customer's PC now; they are an older couple who mainly uses the system for little tasks, no major gaming or media or anything (which is funny once you see some of the specs on their system), and though I have some ideas what may be wrong with it, I am unable to pinpoint anything specific, and so I turn to the experts :)

First off, some specs on their system:
It's an HP Media Center PC case, but components have been changed in it from what they've told me. It has an ECS Nettle3 Mobo with an AMD Phenom X4 9500 CPU (running 2.2GHz). The GPU is an ASUS brand nVidia 8500GT. It has 3GB RAM (2x1GB + 2x512MB). The PSU is a LiteOn PS-5301-08HA.

The reason they wanted me to look at it is because they reported that the screen would, seemingly at random, go blank, with a "No Signal" message. The CPU still seemed to be running, but nothing on screen. They said this also occasionally happened as soon as they tried to start up the PC, and would never even see the system post. But again, they said it sounded like the PC was running, but no image. I have the PC at my shop now, and I have been unable to duplicate this issue; I have run Prime95 and MSI Kombuster just to stress test the CPU and GPU, but so far everything seems to be fine.

Hi & new year on you all! 2010 huh!!

Not quite sure where this one sticks - so I picked the 'general forum'.


1. Computer, at start up, sometimes can't find my monitor. Only way is to start the computer with the monitor switched off; then turn the monitor on at a certain time during the booting process (when I here a motherboard-beep). Occasionally the connection will be broken anyway (and I'll have to mess with the 'reset/-start button). I generally get to the motherboard page and BIOS settings. But sometimes not even that and then the only solution is to leave everything off for a while (minimum a couple of minuts ? but not exactly sure).

2. Computer lose monitor when it to goes into sleep mode. This only happens if I leave it inactive for a long enough time. I can usually retrieve it if the display's gone out only for a short while, as usual - by pressing keyboard or moving mouse.

My hope is to find a solution that doesn't involve buying a new monitor.

A:LCD Monitor loses contact with computer

Go figure, I have this problem all the time when starting the computer after it has been off all night.
Basically, when cold, pushing the power button causes the many system fans to start running, and I can see the little blinking lights of the CD-ROM and CD-DVD Drives as they cycle, but no video...and no sound, no wonderful Windows 7.

What I do to get the computer working is Push the power button (cold start), WAIT about 35 seconds, then re-start by pushing the main power button until the computer/Fans shut off, then quickly push it again to restart. Upon Restart via this method, the computer then BEEPS merrily, the video kicks in, shows the bios setup screen then everything proceeds to windows startup as normal.
Never been able to figure this out. Plenty of power from my PSU (see specs). Just have learned to deal with this minor irritation.

I figure it must be a video card problem (or possibly a signal problem), but it has always worked upon restart, so I gave up worying about it.

I know this is not a solution to your problem but I thought I would share that "others" are having similar problems. (even if they are not exactly the same problems)

Ever since I bought this computer there's been problems with the monitor display. Sound seems to work all well - only the monitor goes "clicking" - switching between nothing (black) and the Fujitsu/Siemens logo with a clicking sound. Sometimes it's enough turning the monitor off for a couple of minutes, sometimes not. This analogue monitor is a couple of years old but works fine periodically.

Weather I connect it to the onboard or separate card graphics makes no difference.
The problem has never occurred while windows 7 is up and active. It either happens at start up (sometimes then it will not even display BIOS) - or as the computer has been "asleep" for a while. So now I've set the power saving mode in windows to 'never'. This improved the situation but far from solved it (the different BIOS modes S1 and S3 had no impact at all by the way).

Could it be power related? PS only 300W.

One thing not mentioned in my monitor specs is response time: 4ms gtg

Appreciate any help and inputs I can get!


A:Monitor loses contact with computer.

It is very common for a repetitive "clicking" noise to be "Power Related". This goes for Computers, Monitors, even Vehicles.

Either the Power Cord from your Monitor to the outlet may be close to shorting out, or something internally (in your monitor) may be loose/frayed.

If you trust yourself with "Hardware" related components, I'd recommend peeking inside of your monitor tracing your power cord TO it's source on the board inside of your monitor. Check for any loose cables or anything that looks possibly "burned" or torched.

(Insurance : If your monitor is seriously as bad as it seems, any damage that may occur when "popping the hood" so to speak, can't be that much more damaging.)

Report back with changes, and possibly a couple pictures.

I have a HP Pavilion a6110n PC. It has NVIDIA GeForce 6150SE nForce 430 and the HP w17e monitor. The monitor has a native display of 1440 x 900.

A few days ago I upgraded Vista with the Service Pack 1. I have always had my PC set to go into "Sleep" mode, which most of the time it doesn't do. This is even true with SP 1. At some point after the SP1 upgrade, I noticed my resolution would change settings, without me doing it.

Today, I noticed my PC had in fact gone into sleep mode, and when I woke it up, etc. once again, my 1440 x 900 resolution was gone. When this first happened a few days ago, I read something about Vista not being able to recognize a "native" resolution, and to correct the problem, it recommended to update the Nvidia drivers, etc. I did this, which corrected the problem, but for some reason, the 1440 x 900 is not kept at times, which I am now thinking is tied into whether or not the PC goes into sleep mode.

Each time I lose the 1440 x 900, I have to uninstall the new Nvidia drivers, and reinstall again, before Vista will display the 1440 x 900.

Any ideas as to what is causing this, and what, if anything can be done to keep it from continuing? In the meantime, I have my PC now set to not go into sleep mode, to see if that does help.

I have just got this new Acer Aspire 8930 Laptop about 2 days ago and setting it up was not much of a hustle. I have managed to connect it to the internet and with my primitive Thomson Speedtouch 536 managed to get my laptop connected via the router to the my main PC, so I could share files easily between the 2.

The problem is that just a few hours ago the laptop started to lose connection a few minutes after I turn it on and I am not able to reestablish it unless I restart the laptop. The laptop connects fine when i start up and I can surf the internet perfectly but after a minute or so the connection is lost and the connection status (Im using vista btw) shows the yellow Limited Connectivity, pointing at the router as the problem. The strange thing is that even when I pull the UDP plug off the laptop, it still shows Limited Connectivity, unlike the red Conenction Lost or something that it should show. But the internet works perfectly for this computer, which uses the same router, but not by UDP (the Speedtouch doesn't have 2 UDP slots)

The Laptop has had it's internet working properly, don't know why it is just turning off moments after start up all of a sudden. I don't even know what triggered it come to think of it. All I did was install Silent Hunter III and installed uTorrent to download the Greywolves mod for it. Anyone might know what I could do to fix this frustrating problem? Suggestions appropriated.

I've a Packard Bell PC, just 2 years old, running Vista Home Premium with all updates installed. I also have Norton Internet Security 2011 installed and kept up to date. From time to time my PC will not start - it gets stuck at the initial (black) Microsoft Corporation screen. To get out of this I restart which throws me into Startup Repair. This proceeds OK. However once it has finished I notice that my NIS is "at risk". I do liveupdate and notice that there's over 90MB of update to apply. It would appear that Startup Repair nullifies/obliterates previous NIS updates and it is as if I have to re-update from scratch (which, to be fair doesn't take long).
Is this normal ? or do I have a setting missing ?
Please advise me

Sorry for the long text, I'm trying to send as much information i have.

Hello forums!
A few years ago i built a new gaming pc because i wanted to be able to play high quality games. But since day 1 i've had nothing but problems. Whenever i play one of my high quality games such as "Assassins Creed, Tomb Raider, Battlefield 3 or Primal Carnage" the monitor goes completely blank showing a "no signal to monitor" sign after gaming for between 5 minutes to up to 2-3 hours. The monitor sometimes also shows different color stripes either for examples: orange, pink or grey. The sound of my friends on skype usually keeps going for about 20 seconds before going silent, the sound of the game shuts off instantly or goes in a loop or starts with a loud buzzing sound. The fans and the LED's on my pc are still going but i can't control anything on the pc making me have to force restart my pc on the power button.
I've been on this forum before talking to this guy who is helping me but he's been quite busy lately so i need some extra help.
I've updated all drivers to latest, i never overheat, the GPU does not go over 51C when gaming and CPU never goes over 51C either.
I've upgraded my 650W powersupply to a 850W power supply and is one of the highest rated best performance power supplies you can find.
I tried to RMA my graphics card but they found nothing wrong with it and sent it back.

Hello again - it's been a long time. I'm working on my Laptop now...


HP dv9330ca laptop running Vista 64-bit. NVidea GE Force 7600 video and Conexant audio. 2GB RAM.

I hooked-up the HDMI cable from the lappy to the TV (Toshiba 32DT2U or 32C110U, not sure) and had no sound through the TV, so I...
Set the sound on the lappy to digital ouput (SPDIF) in Control Panel - still no sound.
Updated video drivers (after google and HP website suggestion)- we have sound (isn't this odd??).
Updated audio drivers - sound is gone (what the...??).
Rollback audio driver - still no sound -.-
Re-install video drivers - we have sound.
Reboot - we still have sound!!
Power down Toshiba display and power back on (left the lappy on and streaming audio and video) - no more sound
Re-install video drivers - still no sound

I have rebooted after all the mentioned steps above. I am making sure that the sound is set to digital in Control Panel but it isn't helping anymore, nor is the re-install of the video drivers. I am thinking that the rollback of the audio driver suggests that I should not try re-installing the newer one, as it seemed previously to cause a conflict.

As always, your suggestions are appreciated.

Thanks in advance!

A:HDMI LOSES sound at monitor power off

** UPDATE...

I did install the newer audio driver and got sound to work. I even re-booted and still had sound. However, when I powered down the system and came back a couple days later, I had no sound again!. Re-installed the audio driver - still no sound.

Any help would be appreciated.

Running Intel Core2 Quad, 8 Megs Ram with GeForce 9800X video card and SyncMaster 245t monitor. System is 18 months old and has run without a hitch until now.
Now computer boots up normally and runs for about 5 minutes then screen goes black and power button starts flashing indicating the monitor has lost sync with the card. Hard drive continues spinning but will not respond to any key entries. Only way to correct is switch the power off and reboot. When rebooting to safe mode screen problem doesn't seem to happen. When screen is working graphics are superb. Only thing which changed which I can think of is I get regular Windows auto updates.
Have tried the following:
1. Swopped screens - same problem with alternate screen.
2. Removed, cleaned and replaced card
3. Replaced cable between card and screen
4. Installed latest Nvidia driver
5. Restored Windows to a previous config
6. Re-installed Vista Home Premium
7. Tried installing Vista 7 but screen blacks out before installation can finish
8. Installed new hard drive and re-installed Vista on the clean drive - no problems until Windows updates then same problem occurs. Has anyone experienced similar problem?
Any suggestions on what next to try?

I hope the title was enough to tell you where I'm at. I have an Acer Aspire One Netbook running XP. I have and LG monitor hooked up and as such is the primary and only monitor I'm using. I am not using the screen of the Acer at all, it's black and blank.

I have set the screen resolution at Desktop>Properties>Settings multiple times, as also I have using the OEM's control applet on the taskbar.

Each time I reboot or restart it loses it's resolution setting and boots up too large. I have to scale it back. I have used APPLY and OK every time it was necessary but it doesn't stick.

If you have another recommendation for a setting elsewhere that would be great, or if you have a registry edit that would give me the ability to set it in the registry.

Oh, a side note here, it seems to boot up okay but then in a second or two goes to the too large resolution. I have asked and asked in many forums. Gets plenty of views but never an answer. I know I had this fixed once several years ago when I had this same configuration, but now I cannot find how I did it. You can bet this time it goes down on a little folder I call PC HELPS where I store resolves to all issues. I'm surprised I didn't do this several years ago, I would not be here and many other forums asking for help that doesn't seem to come.

Thanks for whatever you might know. Jack ":-D

Okay I've been having this problem for about 3 days now. It started when I was on the internet then suddenly my screen became scrambled then the monitor went black and turned to sleep mode. I knew the computer was still working at I could hear music still playing. So I restart and the XP start up screen shows but then the monitor went to sleep mode again. I could still hear the windows start up music though. So I go into Safe mode run Spybot and Adaware remove what it finds then reboot. The screen works everything seems fine just to be safe I install new drivers for my video card, a few hours later it starts doing the same thing. The screen becomes all scrambled and the feed switches back and forth, I have to reboot to make it usable. I come on it this morning and it's still doing it, it's seemingly working fine right now but it will probably come back. Any help?

Hi guys.

I've done all the possible troubleshooting I possible can on this at the level of Office.

I can only think it's something to do with Windows/registry.


User launches Word and gets the User Information screen that runs on first launch (like a Windows RunOnce setting would, only this info is stored in Word under Tools-Options, User Information tab). The information is pre-defined, so she hits OK.

There is no listing under the MRU list. It won't save anything.

All of these settings are stored in the reg under:

I then found that when she originally ran detect and repair, she got an error. The error is described at Q299774, but their fix does not help and, in fact, she still gets the error. (This after completely uninstalling and reinstalling from the hard drive.)

What we've tried.

We renamed
We have renamed the Word reg key to OldWord.
We have completely trashed the Office folder and reinstalled Office.

We tried what's recommended under:

Our question at this point is this, I suppose:

Do we have any recourse besides a reinstall of Windows?

And, if a reinstall, is it worth it to just reinstall without reformatting?

A:Windows XP: Word loses MRU and other settings on each startup

It would definitely be worth trying a reinstall if there a lot of valuable data that would be lost. But has a "System Restore" been tried, if there is a known date when the problem wasn't occuring?

I have NVIDIA GeForce GTX 660 graphic card and BenQ GL2450 monitor. Recently my monitor started going into sleep mode (I thing it says "No signal detect") exactly 15 min after not using the mouse or keyboards. When I click on mouse after that, I get message "DVI: input" (or something like that) and I get signal again.

I checked Change plan settings and sleep mode is disabled. I also reinstalled all my NVIDIA drivers. I noticed in Device manage that I have Generic Pnp Monitor and I actually don't know what is it.

I changed BitComet settings not to start up at starting up Windows.
It is unchecked to start in Msconfig.
It is not in the Startup folder in Start Menu.
Why it is still starting up when starting Windows?

A:Bitcomet is not in msconfig startup and startup but still starts up!

Looks like there is an entry in the registry that has been left after you re-set the settings in the program

Autoruns for Windows

Download and run autoruns and check the items on the startup tab for an entry pointing to bitcomet, you can then uncheck the item to check and then right click and delete the item when you are happy you have all items

Autoruns is a very powerful program and you should only use it to adjust startup of items you are familiar with and are not system critical

I've changed my motherboard into Asus P5GD1-VM. The connections were affixed by the technician. When I came home, I opened the computer and it worked fine. After occurring some problems, I undo all connections then reconnect it again. But when I finally open the computer, the system boots up, all powers and fans worked. After several minutes, like fifteen, the whole computer shut down also the power supply and the fans. Thank you very much in advanced!

I installed a trial version of AnyDVD on my computer directly prior to restarting. Upon restart, my computer powered on (Antec900 case), but my USB razor lycosa keyboard and Microsoft sidewinder mouse, as well as my monitor, didn't turn on. One of the two DVD drives would open/close, the other wouldn't.

I don't have the ability to test each individual component, since I don't have another Platform to place them in.

Any other thoughts/suggestions?
