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.

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.

Hi again everyone! Long time no post. But here I am.

Right now, I'm using my laptop (Dell Inspiron 6400) in dual monitor setup. My monitor is the I-Inc iS220 (22inches) and is connected to my laptop via VGA. The display card is the mobility radeon x1400.

When I connect my monitor to the laptop and use dual display (extended desktop) I find that every once in a while, the screen blinks very briefly. This mostly happens on the 22" display, but sometimes happens on my laptop as well. If i disable my laptop display (manually, or by closing the lid) the blinking doesn't seem to happen. The blinking doesn't happen if I'm using only my laptop.

I'm just wondering if anyone has come across this before and if there's something I can do to fix it?

A:Display blinking intermittently

Dell Inspiron 6400 and ATI mobility radeon x1400 - Display blinking intermittently

Hi matchu,

I have the same configuration as you : a Dell Inspiron 6400 and ATI mobility radeon x1400.
When I connect an external monitor (a Dell 20" widescreen) to the VGA port, and activate extended desktop, I have the exact same symptoms as you : intermittently, the screen blinks very briefly on the external monitor or on the laptop screen. The problem does not appear when I use the laptop without an external monitor.

I have not found a solution so far.

My C720's screen brightness constantly changes from bright to dim to bright. This started all of a sudden 2 weeks ago. I have not dropped it or anything, and while I have not installed any app in months I still tried a powerwash anyways. It's more of a h/w issue though. Anyone has the same problem or suggestions? My machine is out-of-warranty and it's probably not worth it to send it for repairs (and in any case there is no information about how to get a quotation on Acer's support pages). Thanks!

?Blank display with blinking underscore?

Hi every one,

Since one week back I formatted my computer. i.e. i formatted C: drive in hard disk using XP cd. The format has completed and it also took automatic restart also, But the really problem started now after the restart of the computer it not at all showing anything not even continuing forward with initialization of Xp, it just showing blank diaplay with blinking underscore. "i.e. - " . i already formatted the C: drive for more then 10 times but the problem is same. And I tried to install the XP in G: Drive but again the problem is same. Only and only dam blinking underscore

Please help me in this problem by brothers and sis...

A:Blank display with blinking underscore

I would first check the system bios to make sure the hard drive is being detected. Next, check the system bios boot order to make sure the hard drive is the second device to boot from. If all of these are correct boot into recovery console using your windows disc to see if the OS actually appears on the partition. This may be the result of a failing hard drive. You can run a diagnostics test on it from a using a bootable disc. Check your the manufacturer's website of the hard drive to see if they offer a tool for their drives. If not, try SeaTools from Seagate.

Good day,

+First of all sorry for my english.+

I have issues with display on my tecra w50-a-114. *Display sometimes (ca in 5min. period) blink (brightness go on 100% and then back to the current settings).*

I dont know whats happened. I am not aware that I changed some settings. I check all power management settings, but every setting is in my opinion alright.
Have any of you Idea what's happened?

_Thank for all suggestions._

A:Tecra W50-A-114 - blinking display - brightness go up and down


I guess the display brightness level changes no matter if the notebook is connected to the AC adaptor or battery mode? Is this correct?

Usually the function keys FN + F7 and FN + F8 increases and decreases the computers brightness.
But I don?t think that theses function could be related to your issue.

To me it sounds a little bit like display panel hardware problem? but this is only my personal opinion?

Hi. I fix laptops for a living and a customer came to me recently with a G505 that does nothing. Switching it on, the display comes on, but that consists of a non-blinking cursor at the top left of the screen and nothing else. None of the function keys does anything. The cd drive clicks on start up, the indicator lights work fine and the hard drive works (it spins and is not damaged, I took it out and tested it) but there is no sign that anything is being read from it. The fan works, the CPU heats up but - nothing happens! It has Windows 8 installed and uses UEFI. This laptop was manufactured in 2014, it's hardly been used and is in perfect condition.  Has anyone ever seen this issue, I haven't managed to find anything anywhere about it. Any advice would be most welcome as I have run out of ideas! Thanks.

Remember that just because Fans run amd CD Drawers open and close doesn't mean the PSU is working properly. It could still not be providing the required power to run the motherboard. And the PSU is usually the least expensive and easiest fix as well.

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 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?

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?

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!

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?

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.

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!

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.

Hello,Everything was working correctly on my W530 until I installed NVIDIA driver update my external monitor (VGA or ID-port attached) blinks for a fraction of a second every 5 to 10 seconds - very annoying. - Windows 10 64-bit- Intel HD Graphics 4000- NVIDIA Quatro K2000M Does anyone know what might be causing it and/or how to fix this blinking? Thank you!

Had this same problem (blinking screen on external monitor; every 9-10 seconds) this moring on one of my W530's running Win 10. Wasted 2-3 hours doing all sorts of things with Windows updates (first choice as they often cause problems all on their own) and then restoring earlier configurations and who knows what else. Nothing worked. Saw your post and checked my NVIDIA driver. Lo, it was the one you cited. Rolled back the driver in the device manager (right click, properties, driver tab and rollback button). The machine has been running for about 4 hours now without so much as a hint of a flicker. Thanks for your post, hawk98. It held the clue to the solution. Wouldn't it be wonderful if MS, Lenovo and NVIDIA could coordinate these things better ... or even, at all?

Bought a brand new Lenovo y50-70 3 days ago, first thing I did is upgrading to windows 10 (the update message popped straight away), after the upgrade I manually updated nvidia drivers to the latest 355.82. Since then I have this message pop up randomly, sometimes every minute, sometimes every hour and 1 time I tried connecting the laptop to a tv and it kept popping in an endless loop and I had to restart. Also and even more upsetting for me is the problems with the screen, what's upsetting is that I'm not sure if it's software issue or hardware, basically my screen is blinking at random (like half a second black screen and back to normal), mostly when I'm surfing I noticed and less (or even none) when I'm gaming. Also (tho more rarely) I have horizontal colored tearing lines, but the blinking is much more common. So what should I do with this laptop? How can I fix this?

A:Y50-70 screen blinking and "display driver stopped...

Hi, as for the "driver stopped working" thing, try to install older version of the driver, maybe this one isn't stable. or just clean install your version again. As for the screen flashing, I think I have the same problem as you do. I'm almost sure it isn't software related, because it happens both using Intel HD graphics or Nvidia graphics. There are also those lines in here, they are more visible while being on white or black pages. Sometimes I feel like the screen couldn't refresh itself fast enough, and the image is slightly displaced, and after a very short amount of time, like you said - half a second or even less, it goes back to normal. Also, the worst thing that is happening to me(~10 times since I bought the laptop, which is maybe 1,5 months ago), not sure if it happened for you, is this: - feels like all the bad things happening to my screen packed in one gift. To fix this, I need to restart pc. I am not sure what we can do to fix this. I would like to send it back to Lenovo for repair or replacement, but as you said, it happens at random times and I have a feeling that they would just say that everything is fine. From what I have read here, it is probably LCD cable fault, or something is wrong with power supply.

I have a Stream laptop that isn't working properly.  When it turns on, the power button lights up and stays lit but nothing is displayed on the screen.  There is a light next to the power jack on the computer which is blinking rapidly after turn on.  I found this site on the HP support page which outlines a few ways to try and troubleshoot the problem.  Based on this page, it's either the AC Adapter or the battery.  The AC Adapter I have does not have any light on it so it's hard to know which of the two parts is faulty.  I used a voltmeter to test the AC Adapter's output and it is outputting the correct voltage.  These leads me to believe that it's an issue with the battery, but I was just curious if there's any way to be certain before I go purchase a new one when it might be something else at fault.  Any advice would be appreciated.

I'm working as a student assistant at my university. The computer that I use at the desk there is a Dell GX 280. When I start the computer, the monitor works fine until I reach the login screen with the "Press Ctrl+Alt+Dlt" box, at which point the monitor goes black for a second, then returns, then goes black and so on. The monitor power button remains green throughout the hissy fit. This can last anywhere between five and ten minutes, regardless of if I log on or not.

Considering that the computer belongs to the university, I can't take it apart and look around inside. Despite this, if the problem most likely involves hardware, I can notify someone to (hopefully) replace it. What do you all think?

A:LCD monitor screen blinking on and off

Hello @shan678, I understand that your HP w15e LCD Monitor keeps blinking off and off and you are seeking assistance in getting it fixed. I am providing you with some steps you can try below: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 itIf the above steps did not resolve your issue you can try the monitor on a computer or other device to see if the issue persists. If it does I think it would be best if you contact HP Technical Support for repair options.Thank you for posting on the HP Forums. Have a great day!

I know there have been posts on this subject before but none similar to mine.
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.
The computer consists of MS-7246 (Intel 975X Platinum) MB
Saphire X1600 Pro 512Mb graphics card PCI-E
Two Serial HD
Several printers and 2 DVD drives and one USB DVD drive, two external USB HD

I think I shall have to get a new graphics card but some of the new ones seem extremely power hungry so a new power supply looks inevitable unless anyone can suggest a decent graphics card that is greener. I do not use the PC for games but do use CAD & graphics programmes that are probably fairly demanding.
There is of course the possibility that someone may know the cause of the problem and suggest a solution that doean't require any hardware mods. Although I have tried rolling back the drivers and got rid of the AT... Read more

Hello all, my current irritation is "blinking".We get freeze,blink,reopen, with partly messed up page, quite often, especially doing emails and adaware scans, but also apparently randomly. We have up to date Norton anti virus, Ad-aware,Spybot and Spyware blaster. Could this be some well hidden spy prog taking "snapshots",or am I being paranoid? I also installed the latest Nvidia driver for the monitor but it made no difference either way. This is a system that did have lots of junk on it (teenagers!!)-but Im trying to take good care of it in the last few months. Another idea is maybe the monitor is on its last legs? (about 21 months old, lots of use)--any ideas? love and peace.

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.

This is normal for some systems, depending on the hardware and drivers. When the display comes back on, is it dimmed with the UAC dialogue box present? If so, then this is known as the Secure Desktop. This is not the desktop itself, rather it is an image of the desktop which contains no clickable content, save for the UAC dialogue box.

A:Green Light On Monitor Keeps Blinking

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

I'm helping a friend fix their computer monitor and I'm a little stumped!

They've got a Samsung SyncMaster 930B monitor with constantly blinking green light and no images displaying, just a black screen. Pushing the power button on the monitor does nothing, not even turn it off. Unplugging and replugging it also does nothing to the blinking light. The screen will not turn on, not even during reboot. 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.

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.

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...

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.

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.

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?

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?

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

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.

A:Monitor blank, power led blinking green

So on a cold start up - if you just press the start button - monitor won't display anything. But, if you hold in the start button, you are able to get a display?

I just want to make sure I am understanding correctly.

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

Motherboard:ECS P4M800-M7
2x512 RAM DDR
Ati Radeon 3450
Pentium 4 2.66Ghz

I really don't think this is a software doesn't mke any sense.Oh and the RAMS are tested with memtest.

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.

Any hope of returning this to sanity?

Im new here so sorry if this is the wrong place to post this.

Here is my problem:

I have just recently purchased a new Philips HDTV (32") and I have connected my pc to it via hdmi. I use a dvi-hdmi converter via the DVI port on my graphics card (NVIDIA XFX GeForce GTX 260).

The screen blinks and changes to black for a second usally displaying no signal or unsupported format in the top right hand side of the screen. Then it switches back to normal. The blinking happens randomly but never takes longer than a few minutes to happen.

I have all the latest Nvidia drivers installed.

One more thing I had a 32 inch tv before this one and it worked ok. It had issues with the text being blurry and it ended up blowing .

But any help would be really appreciated!

Thanks in advance!

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 have attached two separate images, screen shot of my device manager and display properties and a screen shot of the same image on my mothers PC. (which is also a Dell Inspiron 6400)

On my PC, In my device manager I can not view the display adapters (there must be something installed and I do not have visiblilty?? correct??)

Also, on my display properties I do not even have the option for Multiple monitor support. (these are the same PC's)

Hello folks,

I seem to be having multiple problems all at the same time (all of which may or may not be related) but let me start from the beginning.

This all started when I tried to connect my Inspiron 1720 laptop to our television. For some reason my laptop froze, the image on both my computer and TV had white lines across it, and so I turned off my system since it was locked up.

I restarted and began having display problems - first windows were not opening in the desktop area. They would open in the system tray, but were "unreachable" by the mouse. I played with display settings and got the screen to fit...but now seem to have 2 primary problems:


Whenever I play games, view pictures, or Windows Media Player, I see strange "plaid boxes." However, the desktop is fine and everything else appears to work fine. I contacted NVIDIA and I have installed different driver versions, as well as the OEM (Dell's) driver's - all did not work - I still saw the distorted images when playing games, viewing pictures, and videos.

I have also completed System Restore's to points prior to when I was having the problem - unfortunately that did not work.

Here are screenshots of what I am seeing:

The first set of pictures that you put up look like classics examples of bad video RAM. In a desktop PC I would tell you to swap out the video card with a differnt one to verify that is the issue since in a few cases bad drivers can cause the issue but it's highly unlikely. Professional service by a local non big box computer shop is your best bet at this point.

Hi I made a thread yesterday regarding a minor PC problem I had while trying to install windows XP on my uncles PC the problem was solved thankfully.

I now have an even bigger problem of my own with my PC.
I turned my PC on in the evening and the monitor screen was blank and displayed a blinking orange light, the fan does come on. I doubled checked the wires to see if any were loose but everything is inserted correctly.

What’s weird is the PC that I was installing windows on yesterday was doing the same thing but once you turn it off and turn it back on it would be fine and load windows.
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.

Once I finished installing windows on my uncles PC I turned my PC on and watched highlights of a soccer game so it actually was working last night. But I have no clue as to what has happened?
Can someone please help me?

Tonight I was playing a good old game. I minimized to my desktop while the game was running and pulled open Windows calculator, did some calculator stuff, but then the computer goes into a blue error screen and then restarts. A few moments later, the display on my monitor suddenly turns off as if it were put to sleep. And even if I turn it off cold and restart the computer, nothing appears on the display at all, not even a BIOS logo screen. So weird.

I have a Benq FP7IE+ monitor that has suddenly stopped working. Here's the breakdown:

-when you turn the monitor on when hooked to a computer it will sometimes show the display for a brief moment (ie. showed HP booting screen at startup) and than stops displaying, but the blue light stays on the unit as if it is receiving a display. Other times it will display nothing at all, but the blue light stays on.

-with the blue light on if you attempt to press any of the menu buttons on the monitor itself again nothing is displayed.

-I don't believe that it's a refresh rate or driver issue even though I reinstalled the driver and hooked the monitor to PC running in safe mode and still no display (even though the blue light stays on).

-not the VGA cable, tried another, same result.

-hooked monitor to PC with the identical monitor working on it, same result, no display.

-if you unplug the power cord from the monitor and then plug back in and power back on it will always show the "Benq - Energy Star Qualified Monitor" screen as bright as ever, but then nothing is display even though blue light stays on.

-tried monitor on 3 different computers, no display on any of them.

Any idea what might be causing this? I apologize for being so long winded, but I wanted to include as many details as possible.

I recently got a monitor from one of my friends saying that it was broken. Its a Dell 19in LCD. I have my main monitor a 22in Samsung wide screen So i just plugged it into the second DVI slot on my graphics Card. When i went into the display config i set up dual monitors just to see if it was working. The dell monitor would blink up then quit on me.

When i was messing with the Display settings I made the Dell. Not my Samsung the Default Monitor. I unpluged the broken Dell and restarted. Now my computer regognizes the Samsung as the second monitor and it just shuts it off and recognizes nothing as the main.

I managed to get it into safe mode and it recognized the samsung but every time i try go back to Normal Start the screen is blank.

How can i get it to recognize the Samsung as my main?

Hi - I have recently acquired a new work computer with 1 widescreen Dell monitor (Dell E228WFPc 1680 x 1050, Monitor A) and my older 4:3 monitor (E178FPc 1024 x 768, Monitor B). The graphics card is a NVIDIA GeForce GT 620. I cannot get them both working at the same time on an extended display.

One is plugged into (excuse my slightly less-than-technical language here!) the 'main' monitor port and one has a VGA-DVI adapter.

When either monitor A or B is plugged into the main port without the other plugged in, they work fine.

When monitor A, the widescreen, is plugged into the main port and B is plugged in via the adapter, A works perfectly and the PC detects monitor B (if I set it to extend displays, programs open in that screen but I cannot see anything - the screen is completely black).

When B is plugged into the main port and A is on the adapter, B boots up normally until the point where I would usually see my Windows log in, when it goes black and I can only see and move the cursor.

I thought it would be a case of adjusting the screen res down so that they weren't so drastically different - in fact I'm still sure that would help but I can't get the smaller monitor B to let me do so and it doesn't seem to make a difference when widescreen monitor A is plugged into the main port with B in the other?

That is usually normal. Try dragging a window over to the other monitor and see if it works.

I ordered and today received a new Gateway DX4831 07 Window 7 Desktop Computer and a new FHX2300 23 inch Gateway Monitor. I connected the monitor and computer in accordance (I used the HDMI cable connection between the computer and the monitor) with the included documentation double checked the connections and then turned on the monitor first and then powered up the computer. The monitor displays Gateway for a second or two and then after about 10 seconds it quickly displays no signal before going completely black. Upon turning on the computer, it beeps once and then after about a minute I hear a whirring sound as if the hard drive is turning. After that, the computer is very quiet (as I have read in reviews that it should be), but the monitor remains black no matter how long I leave the computer on. This is the second Gateway DX4831 07 I have ordered/received in the last two weeks. The first one did the same thing and I sent it back and reordered the same model hoping the second one would work. I really want to keep this computer rather than send it back a second time since it is full of features for the price. Gateways support is virtually nonexistent so this is not a reasonable option. All I can do is return it for a full refund within 30 days of purchase. Can you tell what the problem is likely to be and how I can solve it so that I can keep this computer.
