What can I say?  When I find something better than Cerberus (VA-CTCS),
I'll be glad to recommend it.

Meantime, in my experience it's been rather rare for hardware problems
to reside in GPUs _or_ CPUs -- and when that's the case, it becomes
rather obvious from the specific symptoms.

Anyway, I've been meaning to circle back to what Joseph said about past
cooling problems:

  The cpu fan has been in bad shape for some time... it's got some 
  cooling now, but I can easily imagine its lifespan was shortened 
  by overheating in the past.

This is astute, sir.  I would, in your shoes, take careful note of the
fact that heat damage to computing hardware has pernicious long-term
effects.  I would be very skeptical of the reliability of -any-
computing hardware that has undergone significant overheating episodes.

At bare minimum, any component of mine that went through a major
overheating episode would be classed as suspect from that point forward.
It would be unlucky for that unreliability to manifest as freeze-ups
rather than component failure, but that _does happen_.

Man, though, ten-year-old Opteron systems!  Those were awesome!  That's
exactly what my employer California Digital Corporation had as its
bread-and-butter around 2005:  dual-Opteron 2.2GHZ 1U rackmount servers,
in its case.  Those were fabulous for their day -- and also generated a
prodigious amount of waste heat from the CPUs:  In some cases where the
CPU fans seized up, I remember that the motherboard actually got

One way to simplify the diagnostic matrix, Joseph:  Look at a calendar.

the awesome experience of ringing out the old and ringing in the new
