Problem with games

[olikomerc]

After a 10-15 minutes of playing some game, my computer suddenly restarts. I disabled "automaticlly restart", there isn't errors in "Event Viewer", there isn't BSOD. Computer is not overcloked, everyting in BIOS is set to "auto". I tested with Prime95 about 20 hours, and after 8 hours there was an error in "Worker thread #2 -> FATAL ERROR: Rounding was 0.4873046875, expected less than 0.4 ", but the Worker thread #1 didnt had any errors. I tested on a clean WinXP-SP2, without drivers or programs. Also I tried to install all the newest drivers and its same thing.
The MB, CPU, VGA temperatures are OK, i'm monitoring them with everest.

Configuration is:
MB: ASUS P5K
CPU: E6750
RAM: A-DATA 2x1GB DDR2 800
HDD: WD 320GB SATA2 16MB
VGA: PALIT 8800GT 512MB DDR3

Please if anyone can help me ???

I have almost no experience with Prime95, so I am just guessing in all honesty.

That said, it sounds like it is referring to your CPU. Try testing your RAM with Memtest86. If your RAM checks out okay, perhaps try another CPU in your PC if possible.

Yes, I forgot to wirte in my previous post that I've tested RAM with MemTest86 about 10 hours and there was not any error. And I think maybe the problem is CPU or MB.

Any way you can try another CPU in your machine?
