The "thermal event" pre-POST message points almost exclusively to either CPU
or CPU socket/mb failure.

In most instances I've seen, it was simply due to CPU overheating due to a
failed chassis fan, etc.

sc400 or 400sc? i only know of a sc420, sc430 and sc1420 so i assume you are
talking about a 400sc. if so read on...
the poweredge 400sc has a garnered a reputation for random reboots and blue
screen of death due to leaky capacitors near the processor socket. look on
your motherboard to see if any of the capacitors are leaking or bulging at
the top and then talk to dell about getting it replaced. here is a thread
from dell's forums about it... search google for many more...

Chris -

Isn't the 400SC the PE version of the Dimension 8300? (Intel 875 with
different plastics and a couple other minor mods)?

I'd not known those to have cap problems on the board, but perhaps as a
'server' that might be different....

that is right. perhaps they just happened to use some inferior capacitors
on a batch of the pe motherboards. it doesn't seem to have happened to all
of them, but too many of them for dell to ignore. there have been reports
of out of warranty replacements offered by dell to customers with failed
boards. here is another forum site that has a relevant thread on the
subject... great resource for other poweredge related questions/answers...
