More and more it sounds like a hardware issue. Hmm, every time X is running, and you say you had one video card fried - how did it fry? Also, is this machine on a good quality surge protector? Have you had a thunderstorm, or power outages recently?

The vendor told me that the particular video card model (I forget which) had some flaw. In any case the fan stopped running, and it heated up. I usually use the machine remotely but I was at the console at that moment. The monitor started flickering and then went gray.
The vendor sent a replacement, but I had thrown an old ATI in before it arrived. When the crashes occurred now, I finally put in the replacement. Same behavior.
The surge protector is good. I live in NYC and the biggest environmental hazard is the cleaning lady, who has in the past tripped the surge protector switch.
I fear you're right about the hardware. But as far as I can tell everything else works fine. I went overboard in buying two quad processors -- so I could live with one if that's the problem.
