its been doing this more frequently and is starting to get irritating. I'll try to load WoW, and about every 1/3 times my screen will blank out, followed by my music burping/skipping and i get the No Signal Input message on my monitor. now its started doing this with NFS:Undercover, KotOR, and even when it sits at idle. and it'll do this in-game too. i think its my video card, but i hope not, because i only bought this setup in july!

The first thing i would do is uninstall the drivers for the vid card and install the latest.

Check the heat and make sure its not overheating.

i just installed the latest drivers yesterday to see if it would fix the problem. and i dont think the pc is overheating, its at about 88*F right now, and usually doesnt get over 95*

Might want to check and make sure the fan is spinning,
and the heatsink, and card are seated properly.

Had the same problem a while back. No signal from the monitor about 10mins after boot.
Turns out the GPU had roasted the fan, it was all frooze up.
So I replaced the fan, and that fixed it.

i dont know what i did, i just unscrewed my side panel and unplugged a fan, but it seems to have stopped. we'll see if it worked.

I had to turn the fan speed up on my 8800GT, because with it it locked in at 20%, it would sometimes start bugging up, and switching between fullscreen and windows very slowly after a few minutes.

You can download riva tuner.

All you did was unplug a fan and it fixed it? It would be hilarious if that fan was the straw that "broke the camels back" on your PSU. Were you by any chance piggybacking on your GPU's power plug?

Just throwing some random thoughts out there.

nope. and the fan was plugged into the mobo. i havent done any serious gaming since, but it seems to have stopped crashing for now.

i had a fan that had a short on it, it would cause machines to have dickey fits no matter what machine it was or what psu it was on
