One of my friends has one of the most unstable systems known to man, and i was just wondering if you had any ideas about what might be wrong. It seems like a heat problem, but he has a FIC AZ11 mobo, so we can't get a temp reading. He is running a T-Bird 800, not overclocked, a Geforce 256 SDR, and SB Live. He has a slightly better than standard heatsink on the processor, and it still crashes , even with 2 80mm fans on the processor and the side off of the case. The heatsink gets hot, so its not a problem with a bad fit there. Problem might be that he only has a 250w ps. Any ideas?
