PC freezes in games.

Lately my computer has been randomly freezing in games like STALKER and CoD4. It's getting on my nerves. I can play a game for hours and it will not happen and other times it occurs just seconds after it starts.

The CPU is 14+ hours Prime95 stable. I thought it was my GPU OC at first, but after putting it back down to stock I experienced a freeze. I've tried several different sets of drivers. I will mention that my 8800GTX never froze...

Is there a good GPU test I can run overnight to confirm it is the GPU?

atitool will let you know how stable your gpu is in short order.

that is the cpu intensive test you were running, right? do the problems continue if you put your 8800gtx back in (if you still have it) ? are you memtest stable?

I ran 3dmark 06 for 6 hours straight... no freezing.

When STALKER froze I noticed the HD load icon was up... is it possible for a HD to freeze a game?

I also wonder if its the crap SLi technology... when I was able to recover from a freeze it said the problem was with some nvidia file.
