HELP! Montior keeps losing signal bad monitor? Or bad video card?

post #1 of 4
Thread Starter 
I've been troubleshooting this problem for a while now and I cant seem to pin point the problem. My monitor just randomly shuts off, says power save mode and goes blank but everything else on my computer stays running.The only thing i can do is turn the computer off and on to get it to come back. Its so random, it happens while gaming, or watching a movie, it was even doing it sometimes after I restarted right before the windows login screen. It also happened after the bios screen and while windows was loading it would just hang. I'm trying to write this post asap before it does it again tongue.gif. Sometimes my computer will be on for awhile and it wont happen. And then the next time I turn it on it will happen within 5 minutes.

Things Ive done so far:

All settings are back to default, bios etc. Updated bios.
All drivers are up to date. Reinstalled video drivers. Tried old drivers too.
Replaced psu, video card pci cables with new ones. My monitor power cable was coming apart a little at the end. So I thought that was the reason but bought a new one and my problem still happens.
Air sprayed out everything no dust.
Tried a different monitor and still the signal cut out again.

Ran memtest95 on my ram couple of passes with no errors.
Stress tested my video card for overheating issues. No problems. So the video card isn't over heating. Either is the processor.

Not sure what else to do, any help is much appreciated.

Thanks.

Sounds like you've tried everything, except a different monitor!

Then it's pretty clear.... card can be bad and still not overheat, try different one.
