Echoing Jack's comment, I'm not sure this is a heat

go of the reset button prior to POST. If the machine is
starting cold a processor wouldn't overheat that fast but
I haven't yet read all of your thread.
I think there's also an opportunity here to do some sort
of remote debug with you if we can find anything that does
boot.
On quite a few occasions I've had machines that won't boot. Memory is
notorious for causing a black screen on boot, no beeps, no nothing.
My first PC (Cyrix 686) eventually cured itself after I'd reseated the
memory 3 or 4 times. This machine, I nicked its 2x8GB for another
machine and replaced it with 2x16GB - that took several reseats before
it eventually worked. I'm sure I've had others ...
Okay, if Jude is blind he wouldn't see if the problem is "nothing
happening", but on any machine that won't do anything that is the first
suspect...
The other thing is, if the mobo and processor aren't bought as a
"matched pair" you could get hit like I did with the first incarnation
of this machine - the mobo and cpu were allegedly compatible, but the
bios wasn't - I had to RMA the mobo, they upgraded the bios, and then
everything allegedly was hunky dory. I still haven't rebuilt that mobo
though ...
