Weird problem with monitor or graphics card or drivers. Help me determine which.

post #1 of 3
Thread Starter 
On my old PC I noticed yesterday that there was no image on the screen when I tried to wake it up (monitor put to sleep, but not system).
Rebooted and still no image.
Tried with another monitor and showed image fine.
At this point I was thinking there was something wrong with the monitor, so I plugged it into my new PC and it worked.
Plugged it back into the old PC and it was working again.. just assumed there was a loose connection somehow even though they all seemed fine.

Today, same problem.. no image. So I try plugging it into the other PC again and this time it doesn't detect it.
Plugged it back into the old PC with another DVI cable and still no luck.
Plugged it in with a DVI to VGA adapter (graphics card only has 2 DVI ports) and it works.
At this point I assume it is the monitor's DVI port.
I try uninstalling the NVIDIA drivers and it works on DVI.
Clean drivers in safe mode, reinstall NVIDIA drivers again and it seems to work fine on DVI again.
Computer goes to sleep, I try and wake it and I am back at step one.

Plug the monitor into the new PC and this time it detects it.

After the new PC detected it, I plugged it back into the old PC and now it works again... grrr. Tried disabling monitor sleep, but would like to be able to fix it properly.

I accidentally unplugged the monitor while it was on, and now it won't get a signal again.



I am really confused and at my wits end.. some things make me think its a faulty monitor, but then other things make me think it is a driver issue.

Maybe someone here can see this problem more clearly than me.. I am tempted to just go out and grab a new monitor, but it will suck if the same thing happens! Any suggestions as to what might be the cause?

My best guess: the fluorescent tube in your monitor is closing in to the end of its life.

Thanks for your response, but if this was the case why is it only the DVI input that is affected, while the VGA works fine?
