I recently had an alpha die in a similar manner.  Turns out it has 6
lines in the power connector that supply some voltage (+12V maybe?)
simply because it draws so much current that it needs all 6 lines.  Well
one of the wiggled a little loose, and the other 5 got so hot they
melted the connector and burned the motherboard.  Wasn't too hard to fix
-- scrape off the carbon scoring and re-seat the connector.

Anyway, check your power connector.  0V to the processor will make it
cold.  :)
