It's not overclocked, but I'm running memtest86 now and I noticed its reporting the memory is running at 207mhz instead of 667? When its finished I'll take another look in the BIOS. Its been going for almost 45 minutes now without crashing so I'm doubting the memory is a problem.

Edit: Doh.. looks like 207mhz was the FSB, so yeah, it was overclocked. Took help from both of you for me to realize it. Hopefully that'll take care of it. I'll let LFS run for a while and we'll find out.

My computer will randomly lock up during game play in any 3d game, and only 3d games. Its been doing this since I built it a few months ago and its really getting on my nerves. I tried replacing the power supply without any luck. The computer is a Athlon X2 3400 (or 3800 or whatever), pci-e Radeon X800 with 1gb of 667mhz memory. I'm almost positive neither the CPU nor the video card are overheating, as immediately (seconds) after a lockup, neither heatsink is hot to the touch.

Unfortunately I don't have an extra video card or memory to swap out, which are my next two guesses. I suppose I could try removing the heatsinks and reapplying thermal paste, but I'm fairly certain they should be good already.

Does anyone have any other ideas or things I can try to fix this problem?
