Well it shuts down consistently when the temp reaches around 105 C.
Would a weak power supply cause it to get that hot?  And isn't 68 C at
essentially idle a pretty high temperature?

Also, I think it is an Antec 450 or 500 W 80+ type power supply that I
paid a decent amount for.  So I assume the power supply.

But thanks for the suggestion.  I will maybe test a different supply
to see if that solves it if the thermal paste doesn't.
