I am having some random shutdowns with my system and I am having problems tracking it down. It has only happened while playing Combat Arms and it has happened three times now. I have run Prime 95 for 6 hours, ran memtest for 2 hours and now I am currently running the artifact scanner of ATI tool to test the video card. So far, nothing has shown even the slightest error. All of my temps are fine too, so thats not it. I never reinstalled Windows after changing systems and that is going to be my next step if it keeps happening. Any idea whats going on with my system?
