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.
