Monitor or Graphic Card?

  BubbleWorks 08:46 AM 10 Jun 11


My PC is giving me headaches! It is running WinXP.

I start my PC and I can see the boot screen on the monitor but as soon as the second page of the boot screen loads, my monitor goes black and starts making a "blip, blip, blip" noise and the little green light on it starts blinking. Sometimes the Windows Logo comes up after a while, but then the screen goes blank again.

My graphic card has 2 digital-out ports, my monitor has a digital-in and an analog-in port.

Things I have already tried:

Use port1 on the Graphic Card - not even the boot screen comes up on the monitor Using port2 on the Card: digital to digital - boot screen, then off digital to analog - as above, but occasionally windows logo

Stupidly, it did work after the 100th reboot yesterday, but my monitor then had a pop-up saying that resolution isn't optimal (was sitting in 1280/960), so I changed it to 1280/1024 and it went off again, now it wont load at all. Windows loads just fine, it is just my monitor that stays blank. It is not going into hibernation like it does, if it doesn't get a signal, that would be an orange light on the screen. It just has a blinking green light and keeps going "blip, blip, blip" - slight madness is creeping in....sorry. It's driving me nuts.

I haven't got a spare monitor or Graphics Card at home, so I am unable to play, would anyone be able to help and give me a guess of what it could be?

AS you get boot screen its not monitor or Graphics card that's the Problem, its other Hardware. Will it Go into BIOS and stay running? if it does its as I said above. Could be the Hard Drive is Damaged, ie Corrupt or bad sectors. Have you tried tapping F5 or F8 at startup to get to Safe Mode or Last Known Good configuration PS if you have another monitor try that on the PC

Wrong screen resolution settings in windows - Basic until windows boots this is why you can see the screen when first switched on.

Boot to safe mode - can you see the screen?

Set to 60hz 1024-768 these are pretty basic settings

reboot into windows and see if the monitor stays on.

This could also be a faulty card, or monitor. Have you installed the latest drivers for your card?

Try that first, they can be found at the manufactures web site. If that fails, you could open the PC and reseat the card in it's slot. When you mention beeping, is it coming from the PC or the monitor? Never heard a monitor beep, but the sounds could also indicate bad Ram.

A lot to look at, but if it will run in safe mode and stay running, then it's likely your problem is software related

Hi all

thanks for the help - I have since found that this is a common issue, the monitor (or to be more precise the capacitors) is broken.

here is a link explaining it:
