I've occasionally had this issue for a few months but it's gotten worst in the last 5 weeks maybe. 2-3 minutes after I run a game, my cpu crashes while playing (most of the time, it's a full system reset). It's a hard problem to troubleshoot, I've tried many things. But it seems to crash at times when it's graphically intensive. I recently re-formatted my c drive, and the problem still occurs. Here are my specs: P4 1.8, 512 mb RAM, MSI Nvidia GF4 MX 440 (64mb ram, with latest drivers installed), Win XP pro (SP2). I think it's a comptability issue, as in an application causes a conflict while running games, it's hard to tell. I don't know much about BIOS, but i might have to tinker my settings. Any suggestions? Please be specific.
