Id also think the motherboard could be a suspect but I just got it back from ASUS warranty center. The system took a hit in a powerstorm and blew a capicitor. It was still under warranty so they sent me a "new" (refurbished) board back. I suppose its entirely possible that this one is also bad though.. Ive just never had a "bad" processor so I don't know what to look for. It's safe to say that either the Motherboard or the processor is kaput right? In either case, Im going to go intel so ill be buying a new motherboard and processor.
