Nearly all the high end 3d games freezes.

[harmaaharri222]

Hello. I have a problem with nearly every high end 3d game. The game freezes at some point (after 5 minutes, sometimes after an hour) in a way that screen goes colorful and stuck. My sound gets looped and only restart button helps. Sometimes it also restarts itself kinda automatically without getting really stuck. I have met this problem at least with Half-Life2, Mass Effect1, Anno 1404, Civilization 4 (RARELY), Borderlands, Farcry22, Crysis, Crysis Warhead. My build is following:

OP: Windows XP Home with Service Pack 3
Mother Board: ASUS P5B (BIOS version 08.00.12)
Processor: Intel Core 2 Duo E8500 @ 3.16GHz (2CPUs)
RAM: 3008MB (2x512 Buffalo 333Mhz, 2x1024 Kingston 333Mhz)
Graphics: XFX GeForce GTX 260 Black Edition (driver 6.14.0011.9621)
PSU: Corsair 750W TX

I ran MemTest86+ V4.00 earlier today and it didnt find any problems with my DDR chips. Then i upgraded my Antec 500W power to 750W Corsair which didnt help the problem either. Temperature with the CPU is about 43-46C and MB 30-33C. I have checked them alt+tabbed while playing something and they never much bigger than that.

Please if anybody have a clue what might be the problem, i would appreciate very much.

Thanks for your time reading this.

What are you seeing for temps on the GPU?
Is the card new or has it been running ok and this just started?
Have you tried blowing out the Video card heat sink with a can of compressed air

I just played Half-Life2 episode1 for 10 minutes until it crashed. Meanwhile i observed the temperature of GPU which was at 74C in the moment of system crash. I've read people playing with this same GPU with temp like 80C until it crashes.

74c is good.
What version driver are you running?
