Problem with monitor blinking

Q: Problem with monitor blinking

My monitor will blink randomly, and usually come right back on, but sometimes it will be off for 10 secs or more.


umm... not sure about the motherboard, I'm not at home. But it has PCIe, DDR3, Socket 775
550W PSU (came with the case, not sure what exactly...)
Intel Q6600 Quad Core
Corsair 6GB DDR3 RAM
NVIDIA GeForce 9800GTX hooked up via HDMI to a 32" HDTV.

Now, the only thing that has changed is the mobo and ram. I haven't updated the BIOS on the mobo yet, but I suspect that may be the issue. I have the latest drivers and updates for vista.

Anyone had problems with a blinking screen before? I've been told it may be that the video card is overheating... that's not it, because this happens under no load at all.

I've also heard it could be the PSU, but I had no problems like this for 4 months before I replaced the MOBO and RAM.

I appreciate any help.

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.

I need some help. I have acomputer monitor that is roughly 10 years old. THe monitor last night decided to suddenly turn off and the power button started blinking. I unplugged the power to the monitor and let it sit overnight. This morning I went and plugged the power back into the monitor and pressed the power button on it. When I pressed the power button the button started blinking again. I have never had a monitor die like this and I would like to know why it died and if it can be fixed. Some more info is that i had only been on the computer for less than 2 hours. I have not spilled anything on the computer, the vent is completely uncovered, and the computer is in good working conditions according to the mannual. I need to know asap please. The tower still works perfectly fine it is only the monitor.

A:Monitor is black and the power button on the monitor is blinking

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.

Iím working on a friends Dell XPS 410.
Iíve installed a new HDD and performed a fresh install of the OEM Vista.
During bootup, or when the computer is trying to do something .. Like recognize a connected external ..
The monitor flashes off several times, for about a second .. The on duration is variable.
Iím using one of my monitors .. Not his, So this eliminates a monitor problem.

This is one of the same problems as was in his old HDD and System.

Any ideas what may be causing the monitor flashing ??

I have a Princeton LCD monitor, model VL1918, that's about 3 1/2 years old. It has started blinking at me even when it's not connected to the computer. In such condition there's a window that appears saying " NO SIGNAL". which flashes for a count of two, then disappears for a count of nine, then on again for two and off for nine.

Is this curable and at what cost?

Thanks for your thoughts.

Ive been having a problem with my monitor blinking / flashing a black screen every 5 min. It always happens when i change screens for example: load a full screen game, refresh the screen, etc... Everytime i start up my CPU the screen blinks. Then i have to turn off the monitor, wait like 10-15 seconds, then turn it back on for it to work. When it does come back on, the graphics are all messed up. Could this be my monitor? Or does it have something to do with my graphic card? Any help would be appreciated. If possible a solution =) Thanks

A:Monitor Blinking

Screen flicker is normal when you change screen resolutions or settings (which more than likely happens when you play a full screen game). However the "messed up" graphics are not normal.

To test this we will isolate the variables. Here your variables are the graphics card and the monitor. You can: 1) attach the monitor to a known working computer. If the screen still acts funny, you know the monitor is at fault. If not, then it is probably your CPU's graphics card. Or you can 2) attach a known working monitor to the problematic CPU. If that screen acts funny, then you know it is your graphics card at fault, or at the very least not the original monitor. If that secondary monitor does not show any symptoms, then your original monitor is probably causing your problems.

Good luck!

If your laptop is still under warranty I suggest contacting the manufacturers, as it could be a hardware issue. If it isn't, try updating the graphics drivers first.

I have a viewsonic monitor that when i plug it in and turn it on, keeps blinking on and off. The way i used to be able to fix it was turning it of and back on manually until it came on, but now it does it automatically and never turns on. It seems like there is a bad capacitor because it turns on, and you can see the screen for like half a second, then the backlight turns off, then the whole screen turns off and this repeats. So i took it apart and noticed that on the power supply board several capacitors were bulging at the top, so i ordered replacements from mouser and soldered them in. Unfortunately it still blinks. I think if i found the same model monitor that had a cracked screen but working electronics, i could swap them out because the screen seems to still be fine. any ideas on other things i could try?

I just bought an hp pavilion desktop 510-p020. I hooked it up to my hp w1907 monitor which is about 7-8 years old. Everything was working fine until I left the system idle. When I returned to the computer the monitor was dark. I hit one of the keys to awaken the computer. Instead the monitor just kept blinking on and off. I tried restarting the computer with the same result. The system itself is starting up so I don't think the modem is the problem. When I click the power button on the display, it turns on for a second then turns off. In the meantime the system startup is progressing. I have tried changing the power cord, checking all the connections, and plugging the display directly into the wall, all with the same result. Anyone have a clue as to what's going on?

I don't know the brand of my computer... I don't think it even has one. It was built for me by my husband Who is in another country for about four months (so it is now up to his uneducated wife to fix any computer problems that may occur)

My problem started when I tried to hook my scanner up to my computer. (my scanner was not USB) Anyway after I got it hooked up and I turned my computer back on the monitor just blinked at me. Absolutely nothing else happened. No power in the tower. Nothing. So I unhooked my scanner and started it back up... and it still did the same thing.

I have checked all my cable connections and even reinstalled the card to my monitor. And I am now all out of ideas. So if I can't figure this out then I will either have to hire someone to come down and look at it (which I cannot possibly afford) or wait four months for my husband to come home.

I am very open to suggestions. Please someone help me.

I have an LG CRT monitor 2 years old. Since the past 15 days, my monitor has developed a problem. The monitor begins to blink continuously on and off each time switch on the PC. The rate of blinking dies down gradually , and finally the monitor shows the display. It is taking nearly 10 minutes for the monitor to stop blinking and show the display.

And, the monitor behaves properly if I do a system restart immediately. But, the computer again blinks continuously if I switch it on after a gap of 2-3 hours.

Please help me out to get out of this trouble. Is there any damage to components inside the CRT? or is it just the power cord trouble?

Yup, it sounds like the high voltage rectifier and it's not worth fixing. Time to go LCD.

I have a HP w2408h monitor that has had blinking on and off problems ever since I began using it with my Surfact Pro 3.  I ran across some 2114 posts on this forum where I found the following solution . . . Step 1. Unplug the power cord from the back of the monitor and the wallStep 2. Hold the power button down for at least one minuteStep 3. Plug the power cord back into the monitor and then into the wall outlet (not a power bar or surge protector)Step 4. Press the Menu button on the monitorStep 5. Navigate to the Factory Reset option and select it I followed those steps and , so far, my monitor no longer blinks (but its had periods like this before so time will tell) My question is about step three.  Why can't I use a power bar or surge protector?  Why does it have to be plugged directly into the wall?

I am currently on a Dell dimension 2400 PC, with windows XP home edition service pack 2 that my mom got in 2003, but the monitor has started blinkling, what happens is the screen will suddenly go black & then start blinking, with a faint light in the bottom corner, I can see the screen contents between blinks. This occurs when; I have been away from the computer a while, upon start up & sometimes when I am in the middle of something. so far what I have done is jiggle/wiggle the cord that plugs into the back of the monitor, & it usually brings the monitor back but it it is taking more jiggling the cord than ever to get the screen back. The computer seems to be ok, watched the diagnostic lights at the back of the computer upon start up, all green no red. but the monitor is very irritating. Is it the cord? before I started up today, I tried unplugging the cord that plugs into the monitor & then re plugged it back in, then started up the computer, all was well for a while, there was no blinking at start up, but then after I was away from the computer for about 10 minutes, moved the mouse & it started blinking again. The monitor is a 15 inch LCD, should I get a new cord for it? will I be able to find a new cord for this monitor? it came with the PC in 2003. Do I need to get a new monitor? is the computer dying?

i recently installed a brand new system in my car that consists of a Micro ATX Mobo - AMD Athlon2 - 8 gb DDR2 1066 - dc-dc power supply -windows 7 and a computer monitor. the computer runs perfectly but the monitor i am using will go black for a second or two at random intervals. the dc-dc power supply has a 20 pin and a 4 pin for the mobo, power sata for the hard drive and another flat 4 pin that i am not using. since the lcd i am using needs 12 volts i connected it to the 12v and ground from that flat 4 pin off the ps. this setup was fine when i set it up on a normal psu from my other computer.. is it possible that the dc-dc psu cant handle the load from the lcd? also i did set this up temporarily in my car to see if it would work and it did. although at that time it was not in its native resolution. the native resolution of my monitor is 640x480 at 60hz. windows 7 for some reason will only allow me 59hz no matter how i try to change it. does anyone have some idea as to what the blinking is caused by?

Brief description:

Upon log-in, my monitor begins to blink irregularly. After several minutes of occasional blinking, the screen will simply go black. Strangely, this blink-to-end-all blinks leaves the monitor in *sleep* mode - I can tell because its power-button light is now orange.

What I've done: Switched the monitor, to ensure that this isn't a monitor problem (it isn't - it happened with both monitors). No new software has been downloaded recently. Do I *need* to call geeksquad or something, or is there a way to determine what is causing this? I'm guessing video card but I know so little about hardware that I've got no reason to support that.

Any suggestions on further diagnosing the issue, let me know. I'm a bit busy at the moment, but in an hour or so I will try playing audio to determine if it will continue after the screen goes off / into sleep mode.

Thanks for the help!

Having recently purchased a Samsung 2693HM monitor and using DVI input, when the resolution is wound up to 1920 x 1200 every now and then the monitor screen will go blank for a second, timing is quite random. I know it is not the monitor or cable as have experienced the problem with another (two) monitors only not nearly so severly as they would not display the same resolution. I have now wound the resolution down and the problem has ceased. Interestingly it doesn't happen when using an analog connection but at high resolution that is terrible.

Although everything points to the graphics card is it possible that the 350W power supply may be a cause? The system is fairly well loaded.

if you are getting no output onto monitors there are only two troubleshooting sources left:

1. you have a bad/loose cable

2. your video card is messed up.

Since you have isolated the monitor as not being a problem, the error is either in your cable or video card.

swap out with another video card to see if that is the problem

It will bootup and remain on for about a minute then the monitor will go black and the off on light will blink and make sort of a clicking noise about once per second continuously. I tried a new vga cord no change? What is the problem could it be compatibility or just an internal fuse of somesort? Works the same way on both boxes, go figure?

Possibly your video card? If you have a video card in that computer try swapping it out with your other system and test it in there, and vice versa (if you have a card in your other computer put it in the one that isn't working and see if it works). If you get the same error when you insert that card into the other computer then that would be a good hint. Or if you have onboard video, well......try putting in a card from another computer and see what happens.

The hard drive fan seems to be running and computer seems to be processing during reboot. I even tried hooking the monitor up to a laptop to see if it would work, with no results.

The computer itself is a three year old HP Pavillion a1340n with Windows XP Media Center Edition 2005. It has Norton Antivirus. Unfortunately, I cannot get in to see if there is anything else wrong with it without lugging another monitor over from somewhere else and trying to hook it up.

A:Help! Blinking Green Light on Monitor

If, as you indicate, you've tried it on a known working system and it still doesn't work then the most likely culprit is the monitor itself. If you can find a reasonably priced repairer then get them to fix it. It usually works out a lot cheaper, tho', to buy a new one.

External monitor shows an odd behavior:
When no apps are present, it works perfectly fineOpera, VLC and some others seem to run fineHowever, screen blacks out sometimes, as if it was changing resolution. This happens on certain occasions, for example when I press CTRL (!) in Powerpoint (if PP runs on that screen), or stochastically (keeps on doing this in Visual Studio)

I am running Windows 8.1 on MacBook pro 13" (2010 mid, 320m graphics). I have an external Asus VW202 monitor attached via 3rd party mini DP to VGA adapter. Main screen works fine. Graphics drivers are updated. No issues occurred on Mac OS X. It also seems that only max resolution (1680x1050) is affected. Any others do not cause trouble.

I have a Toshiba Satellite Laptop P105-S6187 Windows Vista Home Premium.
My brother has the exact same one, and when he goes to log into any site using a password, He gets this 1/4 inch strip ( red, blinking) around the outside edge of the screen.
Now, Here is the story.... While His ex wife and her TEEN age kids were living with him, They had some program put on the Laptop, and his home computer, that records every keystroke. (Trying to monitor the kids.) Well things got bad and She and the kids have moved back east.
He had caught her snooping through emails, bank accounts.... Well you get the idea.
I have looked every where I can think of to figure out what might be causing this flashing red ring, to no success. I have never noticed it happening on my Lap top.
He is afraid that Someone??? Has gotten into his computer and is monitoring his stuff.
Could this be some kind of system warning?

so I just did an OS format on my Aspire 4930..
I formatted Vista to XP because of obvious reasons.

but, after I installed all my drivers proper,
everytime at startup, my monitor would blink once to black,
but only about one second, even less..

it would not blink again for the rest of the session though.
but, when I uninstalled the VGA Intel driver to see if it had any effect,
the monitor didn't blink. it seems that the driver is the problem, yeah?

but I tried installing two versions and they're just the same.
what I want to ask is:

1) will it have any long-term effect?
2) is the monitor adjusting to anything; refresh rate, etc?
3) can I repair this?

thanks very much in advance..

This evening I decided to reboot my personal computer, which uses Vista. Up until this point it had worked fine, including earlier today. Every time I attempt to reboot it, it starts by bringing up its normal white screen about being a gigabyte motherboard. It then never shows any of the data involved with the reboot - instead, it goes straight to a completely black screen, and stays on it indefinitely. There is a blinking green light on the monitor. As the light blinks, there is a faint "clicking" or "flickering" sound.

I have attempted multiple computer restarts, adjusting the monitor cords. None of it has had any effect. There is no error message, at least not that I've had the ability to see. As I cannot see anything happening on the screen, I do not know if this is purely a graphics problem or if there is also a problem with the computer.

Thanks in advance for any advice...

We have new Optiplex 7040. This model has two displayports and one HDMI. VGA Monitors are connected to one of the displayports and to the HDMI using the approved adaptors.
After two months of use the monitor attached to the HDMI began to blank every so often for a few seconds then come back on again. Whatever the user is doing it blanks and appears, sometimes every ten seconds or so.
I've eliminated the monitors by swapping them, so the source is the HDMI connector or the HDMI to VGA adapter. I've put the latest Graphics drivers in place. The system has shown no more problems with the monitors connected to the two displayport adapters.
So I have two questions:1. Are there any known issues that could cause theses symptoms on the 7040?2. Are these the symptoms of HDMI to VGA adapter failure?

From last few days my PC has developed a display problem. (which I believe it to be related to win xp rather than monitor)On switching on start button the monitor remains blank only. The power on indicator turns green and continuously blinking @ 3 secs. As usually I do when any problem encountered with my pc, searched for a solution in the net and found a discussion at one place one with similar symptom. It says to switch off the mains and keep the PC start button depress for few secs and then to go for normal start. I find that It works ok, but the problem is not solved for ever. Next time when I go for normal start same problem appears.

If any body has a better solution pl suggest. my PC is HP with LCD monitor, graphics on board. OS is XP Sp3.

I'm not sure if this is a new problem or not as side of monitor was not visible before - I just moved the pc to a new location so now I can see it. Anyway, it is a blinking light that sits right above the on/off button. I am not sure what the icon that accompanies the blinking light. it  is in the same location. The icon looks like a "can" - maybe it is something related to disk drive.Thanks for any thoughts.

ritkit03,The blinking light that looks like a "can"is the hardrive activity light.A hard drive activity light is a small LED light that illuminates whenever the hard drive or other built-in storage is being read from or written to.Knowing when your computer's hard drive is being accessed is helpful so you can avoid pulling the battery or unplugging the computer while the operating system is still accessing files on the drive, a mistake that can cause corruption of important files.A hard drive activity light is sometimes referred to as an HDD LED, a hard drive light,or a hard drive activity indicator.

A:blinking monitor after installing nvidia driver

Hi r3n311,

Welcome to Vista Forums!

Assuming you are using the correct drivers for the card and your version of Windows, I'm extremely tempted to suggest if the old NVidia drivers worked fine, just revert to them: Restore a driver to its previous version even if it is generally recommended to use the most updated drivers available.

Why are you updating the drivers? Because you do so periodically and noticed new ones were available or because you were having some other problem (if so, what)? Where did you get the new drivers - directly from the NVidea website or elsewhere (if so, where exactly - the website URL if you have it)? If you got them from Microsoft Update, then definitely revert to the prior version.

If you insist on using the new drivers and they are appropriate and obtained from a reputable source (the NVidea site or the computer manufacturer website are the only two you should consider), then download them again to make sure you didn't get a corrupted file and install them again (and triple-check to make sure they are appropriate for the card and your version of Windows). Then go to Start / Control Panel / Device Manager and verify that the drivers are properly installed with no errors and show they are working properly.

Try to play with the settings in Control Panel / Personalization - changing themes, color/appearance settings, DPI settings, resolutions and anything else that can be configured to see if that helps. If not, check with the computer manu... Read more

Allright i've got a really odd problem.
Months ago i made this thread:

Now the problem has been solved and the computer worked fine...until now.
My old RAM broke so i changed with 2x512.
RAM worked fine 1 month but now if i shut down the computer or restart it the PC simply won't start. (no beep sound) The Monitor will act like the computer isn't on
If i let the PC off for 5 minutes it will magically start again only to reboot minutes later and then not booting again.
I don't think this is a RAM related problem as it worked fine and even with the old ram i got some problems (freezes,restarts) Oh and sometimes the computer will freeze forcing me to restart.

This problem occured today.Yesterday i got a random restart so i figured it was something wrong but i didn't payed much attention.

I guess the restarts are BSOD so i unchecked the automatic restart.

EDIT:Yep it is an BSOD...caused by driver sptd.sys (Daemon tools? I don't have it installed though...only Alcohol) as showed by BlueScreenView

I have all the latest Nvidia drivers installed.

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:

Windows XP Media Center Edition SP3

Have a 1702FP Dell monitor (17" flat panel, has both DVI and VGA connectors) that went slightly mad.

If it's plugged in, the power light is blinking orange (twice rapidly, then a pause off, then twice rapidly, then a pause, repeate), and the selection lights (DVI vs VGA) are blinking (#1 on, #2 flashes twice briefly, #1 on, etc-I don't know which is VGA and which is DVI.). The screen is blank.

Pushing buttons has no effect--can't turn it on or off let alone any of the other settings. It doesn't matter if the computer is on, if the monitor is plugged in to a computer (tried both home built PC and Mac), or if the video cables are attached to the monitor. It acts the same, as long as power is connected.

But my one is not even doing that, there is nothing wrong with the monitor has I have brought it recently and I also checked the PC using my brother’s monitor and the same thing happens.

I have a brand new Latitude E7470 that I'm trying to connect to a 4k monitor thorough an E-port plus II docking station. Unfortunately the image keeps blanking out on the monitor, at a variable rate between once a second and once every few seconds. I've tried both a displayport cable and a DVI-to-HDMI cable for the connection, and the result was the same. Changing the resolution did not help either.
I am running the latest BIOS and latest Intel graphics driver from the dell support page (both about a week old). (By the way, the BIOS update messes up the OS installation - buyer beware.)
I've tried many other combinations to trouble-shoot the issue:
1. Different laptops (E64xx), same E-port, same monitor -> works fine
2. Same E7470, different E-port (old USB 2.0), same monitor -> monitor blinks
3. Same E7470, same E-port, different brand 4k monitor, different DP cable -> monitor blinks
4. Same E7470, same E-port, monitor switched to DP 1.1 -> monitor stays black
5. Direct connection between the E7470 and the monitor via HDMI -> works (but only at 30 Hz due to HDMI limitation)
So the conclusion is that the combination of E7470 + E-port + 4k monitor doesn't work, regardless of the exact monitor or exact E-port. That leaves the E7470 as the only logical culprit.
Is this problem a design limitation of the E7470, a known driver issue or a faulty notebook?
Thanks in advance!

A:Latitude E7470 produces flashing/blinking image on 4k monitor connected to docking station

I am also having a similar problem with my 7470. Newest bios and drivers are installed. Happens on both the laptop's screen and using an external monitor through a docking station.
Seems to start after the monitor has been turned off due to PC activity. Can fix it with a restart OR by changing the resolution and changing it back. Both highly annoying options. Switching from external to laptop screen does not fix it, it will continue.
my external screen is using a DVI connection from the dock to the monitor which is also DVI so I am not using some kind of adapter. Removing the connection from my KVM does not resolve the issue either.

With a brand new computer, I would find it infuriating, not just annoying. Is the monitor new too?

First, make sure all the cable connections for the monitor are tight to the graphics card and on the back of the monitor. If tight, then swap monitors. If no spare monitor, most modern TVs support computer input. It is best if you can use the same video interface (HDMI, DisplayPort, DVI, etc.).

If the problem happens on the spare monitor, you know the problem is in the computer. If the spare monitor works fine then the problem is most likely the original monitor.

I note you have "MSI GeForce GTX 980 Ti Gaming 6GB" listed twice above. Are you running with 2 cards?

I have searched, searched and SEARCHED AGAIN for solutions (for years, also had it on old XP machines), and no matter what people say it could be in literally thouasands of threads/replies I've found over the years no one HAS CURED IT OR FOUND OUT WHAT IT IS. Some people call it the 'heartbeat'. I call it a c***.

HELP, this is now driving me slightly crazy!!!!! SOMEONE somewhere MUST KNOW!!!


Even when you are not actively doing anything, the hard drive will remain active, because of background programs and OS activity. As far as I know, there is no way to totally make the hard drive inactive, without disabling it, or shutting down the computer. I'm assuming that the activitity light is the one indicating activity on the hard drive where the OS resides.

If you feel that the amount of activity is abnormal, then check it with Process Monitor:

If that doesn't explain it, then start checking with security scanners for malware, trojans, etc.

Text in a text editor or sometimes a small window like a dialog box, install box etc. will regularly blink. It's not really a screen redraw where it disappears and reappears, just a blink or a refresh.

I've updated the video driver, reinstalled/repaired XP etc etc and can't track down this problem. Could anyone help with this?

OK so here is the deal. THis computer was booting fine and loading in windows. THe problem it had was it was too slow with all the spyware and i decided to give it a format. Windows 98 is the operating system.
The pc is a pentium 3 and was working fine until i cleared the cmos. Now after it loads teh ram, finds primary and secondarary devices instead of going to the next step the screen gets stuck on a black screen with a blinking "_" at the top. From then on the keybaord doesn't work anymore, cause i try rebooting usingt he control alt del, but in vain. Also the f8 key doesn't work.
What i tried is i removed the hdd and tried to boot from it on another pc, and it worked fine, I also had another cpu and i exchnaged it with the one on this pc to see if the cpu was the problem and still the same problem. I kinda know the prob is with the settings in the bios but i don't know what i should set. I would normally keep a copy of the setting but this time i didn't. So what i did was set the date and and the rest of the settings i loaded the defaults. But still i get a blank screen with a _ at the top. Normally i would set the cpu speed and the voltage. The prob is i tried all the cpu speed but it made no differnce ,a and i have't found the option for the voltage. Any suggestions? cause i'm basically just lost!

Hi, i'm suffering from a problem, my computer's screen used to work properly and now suddenly stopped working properly, it's blinking with lots of squares, cubics, here's a picture of what it looks like, any ideas? I've tried restoring the system 24 hours back, didn't help.

A:Screen problem, cubes,blinking.

How long ago did the problem start, and do you know of anything that may have changed, in between then?

My first recommendation would be to ensure that your video cable is securely connected. Also, try wiggling the cables, and notice if the squares change or go away.

Dear Bleepingcomputer Forumites:

I have had this problem off and on for 3 months: my cursor on my PC (a 2006 Dell Inspiron 710m) frequently has an incessantly blinking hourglass attached to it. At the time this first happened, the problem seemed to appear out of nowhere; I hadn't made any strange changes or downloads that might have explained it. I am running Windows XP Professional. I've run an updated version of Trend Micro PC-cillin and it says that my computer is clear of viruses. I downloaded the Microsoft Autoplay Repair Wizard, but when I run the "repair" wizard it tells me that it can't fix the problem. Any suggestions would be very much appreciated!

Thanks in advance, landy223.

A:Blinking Hourglass Cursor Problem

Hi and Welcome to BC,The blinking hourglass (replacing your cursor) usually means that Windows is waiting for a program or process running in the background to finish doing whatever it is doing.A couple of questions come to mind:How long does this condition last? Is it a few seconds or several minutes?Do you know what processes are running at the time this occurs?Is your computer running slower than it used to?Is your hard drive almost full?Do you have more than one Anti-Virus or Firewall running at the same time?You may have found a hijacker that is along for the ride that your Anti-Virus, Anti-Spyware programs are just not finding. Not all of them find all things, all of the time. Certain versions do a much more complete job than others. There are morespecialized products that find only specific types of malware. Trend Micro is a good program but it isn't the only one out there.

Hello Guys,
I am pretty new in this Forum .
I have an Asus X50Z Notebook with a strange Problem.
When it is turned on ( via Power Cable or Battery) , the power light and other lights do come on but NO Display on the LCD:
The FAN does not SPIN most times (it does spin ,sometimes when left for about 5 minutes ....and stops again, with no Display on the LCD )
I have tried Basic Troubleshooting .....removed the battery and held the power Button for 30-60 Seconds and and turned it ON with the Charger and also with Battery inserted but problem persists.
I would like to know if this is a GPU related problem or something else .

Your advisory feedback shall be appreciated.

I wish Everyone a Splendid Easter !!!

Best regards

Yesterday I noticed in my Outlook the title bar and whatever message was highlighted was blinking. I thought it was limited to Outlook so I started researching and found nothing.

I had just put on 10 Windows Updates, so today I used system restore to roll back to before the updates. I still had the problem.

I opened Word, to see if it would happen, and it does. When I am in My Documents it blinks, but Internet Explorer, Firefox, Trillian, and MySpace IM do not.

I've run full AV scan (I use AVG) with no virii found.

Various error messages have appeared on my HP Deskjet All-in-One printer F4180 and now after installing a new black cartridge and clicking Align various lights are blinking i.e. paper type lights, print cartridge lights, power light and resume light. HP Support advice for blinking lights is that the cause is Fatal. As it's out of warranty I cannot phone, email or get a webchat with them so am a bit stuck. Is it likely or certain that the printer cannot be economically repaired as this message indicates?
Any suggestions or help would be much appreciated.

I have read a couple of articles about the same problem. Mine is a little different situation. Everytime the amber light is blinking on the power button, I pull all cords like monitor, speaker, and etc out of the wall outlet except the power supplier. It works everytime. As soon as the cords are out, the amber light become a green right.

This why I am confusing to find a problem. Do you think it is a M/B problem or Power supply problem?

If PSU made the problem, I would like to replace the whole case as normal tower style. I look up a couple of cases on ebay but the back side of the case, in which all connectors like monitor,USB, and printer on M/B are, does not match with an original M/B shape.
Anyone has an experience with replacing a case?

RFH = Request for Help

Hi Everybody,

A friend asked for help with her machine and I haven't been able to figure out how to resolve the problem. I'm hoping somebody here could help.

Apparently there was a strange problem, that caused her to go through vista installation again. Instead of choosing a repair they chose a new install so they have a Windows.old directory now. So their data is safe, and I backed it up.

The big problem now is that after the Dell BIOS screen, it just goes to a blinking cursor in the upper left and I can go no further. F8 doesn't do anything.

I can get into the system if I boot Linux and I can see that the enviornment is a fresh vista install when it comes to programs and layout.

I downloaded and ran the repair disk. The tests look fine, but I never went for the long tests. I ran pretty much every option with bootrec. Strangely bootrec only sees the Windows.old directory as the valid install.

I think the problem might be that one thing points to Windows.old\Windows and something else is pointing to \Windows.

Any idea on what I could do to fix this (being able to boot into windows with a Linux CD), save reinstalling Vista on a clean harddrive?

I have a tablet which I love to use for Photoshop work.. It works great except that some one at Windows decided that it would be a good idea to have animated cursors. A ripple effect occurs everytime I click and animated circle show up everytime I right click or hold down the cursor.

Working with artwork these effects are incredibly ANNOYING, esp since I am clicking all the time and these effects ubstruct my view! Not to mention they are completely useless. I think I know when I am right clicking or clicking and don't see why I need this annimation to tell me that.

Does anyone know where I can turn these effects off? I looked in the control panel under Pen and touch but I couldn't find anything.

I do not think these effects should be standard in the Windows Seven Release. Perhaps they can be truned on as an accesibility feature for those who want it.



A:Wacom Tablet- Blinking Cursor Problem

I don't think it's accessible via the Pen and Touch options, or even in the WACOM pad's own interface
- try in the Control Panel under Mouse..

one of the options under "Pointers" is to "Allow Windows themes to change mouse pointers"
- it's done by un-ticking that box near the bottom..

- see if this makes any difference..

Hello everyone; Because of this problem, I had a notebook changed with the exact same one, for I'd had this problem since the first time I'd turned on the device, and I never solved the issue on that notebook, though I tried many advised solutions on these forums, youtube etc. However, this notebook have come with the same problem. At first time, it seemed like it occurred less than it did on the previous device, and I thought that maybe those solutions would work this time. But it has become more frequent when I have started to run some other applications. I have tried those solutions again; - I have disabled the battery saving modes on Intel Graphics,- I have disabled the adaptive brightness on power management settings,- I have done the BIOS update,- I have done the driver update (done it before but now I also have the problem of updating the driver since the latest update of Windows 10, I can never install a driver update now)- I have disabled the Windows Error Reporting Service and Problem Reports and Solutions Control Panel Support on System Configuration. Despite all these, the blinking never stopped!!! I have been absolutely mad after all these issues. I don't want to make another change of device. There has to be an absolute solution. Please give me a prompt reply. Thank you in advance. *Edited upon wrong usage of vocabulary, sorry..

I have a boot problem where I get a blinking cursor after the BIOS loads. Its a Dell 4500s desktop. I have tried the following:

1) Repair option with Windows XP Professional CD
2) Intalled new instance of the OS (on the same partition "C")
3) Ran Dell hardware diagnostic test on the hard drive - No Errors reported !!

I am thinking there is some kind of a bood sector problem. Need some help (instructions and/or tool(s) to fix the problem.

End objective desired:

a) Repart original installation of the OS (have lots of apps and settings to loose)
b) Copy "documents and settings" folder at least from the current installation on C Drive.

Please advise/help.

I recently dualbooted Linux Mint and Windows 7 on my laptop. Yesterday I removed the Linux partition without thinking, and forgetting about the GRUB bootloader. I'm at a stump now. When I try and turn on my computer, the Toshiba logo appears, then the screen goes blank with a blinking cursor. I searched the internet all of today and most of yesterday, all that did was tell me to do the bootsect /nt670 /fixmbr and all it's variations.

Thing I've tried:
-Repairing it using install DVD
-Bootsect/Bootrec (used any option that would help, none did)
-Reinstalled Mint (GRUB loader reappeared, was able to boot Windows 7 loader, but when I did it went back into the blank screen)
-Reinstalled Windows 7 (didn't help)

Another problem is, when I click on repair, it shows with 3 different Windows 7 installs, Windows 7, Windows 7, and Windows 7 Home Premium. All say they are located on my primary partition, C:\.

So, is my computer a big paperweight now? Or should I reinstall Linux, boot into it, format my entire system, and reinstall Windows fresh? I have all my important data backed up on an external HD. Thanks
PS I'm running a memory test on my laptop now, I'll post results later if needed.

I searched the manual but there is no mention of what this flashing light means. Could it be an exhaust or shorted out battery?

As of today my XPS 13 started to behave in a very strange way.It only boots and works when it's plugged in to a charger, and it doesn't seem to charge the batter at all while it's plugged it, which is stuck at ~48%. When I plug it out, it power off immediately and I have to plug it back in to be able to boot up. Additionally to that, the light indicator below the touchpad is bliking rapidly with an amber light (~3-4 blinks per second).

Dell Dimension 8200 blinking cursor problem.After windows update 3-10-10 (the last item in the eventviewer) the system rebooted and stopped at the blinking cursor just after the Dell bios splash screen.Since this is a classic "can't find the hard drive" blink. I checked the bios. Drive detected ok.( I installed this drive (320gb ide) in July of 09 and rebuilt it with a fresh install and backups)So the first move logically is to boot from xp cd and open the repair console.So. chkdsk /r twice. Still blinking cursor. fixboot. Still blinking cursorfixmbr. Still blinking cursorrepair install. Still blinking cursor(repair install did not reboot at the "starting windows" point, and apparently hung the repair install)Further research time: then. So the original google search that indicated that bios versions for this model (according to Dell support forums circa 2006) starting at A5, fully supported large drives in the bios.(current bios is A9)That apparently was not correct. Either that or marketing was answering support questions on the Dell forum. It supports large drives as long as the boot partition is less then 137gb. There is a small chance that either service packs or hotfixes could have conflicted with and invalidated some firmware/bios patch from the lowest bidder at Dell back in 2006.

My XPS 13 started to act out pretty strange today. It seems like it doesn't not use battery at all, thus I can only boot it up when it's plugged to the charger. The battery indicator shows that it's NOT charging the battery, and it's stuck at 48%. When I disconnect it from the charger while it's running, it turns off immediately, and the only way to boot it up is to plug it back again. Additionally, the light indicator below the touchpad is blinking rapidly (~3-4 blinks per second) with amber light, both when I'm in OS as well as already on Dell splash screen during boot.
Any ideas on what might be going on ? I have bios 1.3.3 which I updated around April.
