Clearly you have more experience than me but you did say gone bad because
of overheating right? Most components I've had go bad did so for no
apparent reason. They just failed at some point. I've never seen a CPU do
that and even old socket 462 Athlon XP's shut down when over heated saving
themselves from frydom. I base that on the fact that the last one I worked
on (2800+) wouldn't run for more than a couple minutes in Windows because
it was showing 70C in the BIOS. After I cleaned the gunk off dude's
heatsink and applied new TIM. Problem solved and it ran as good as new. I
have an ancient PII 333 MHz Slot style CPU right now in my apartment that
runs as well as the day it was built in 1997. An old style horizontal HP
Vectra and I don't know why I even keep it around..

I've seen at least 5-6 CPU's go bad. Sometimes it's just the cache
memory and sometimes the processor. Old athlons would fry pretty quick
if the CPU fan goes bad often just within a few minutes. I've probably
built or repaired 500+ systems just as a hobbyist. I used to average 3-4
full systems a week back in the old days. Now that I don't have a lot of
time, I've probably done new boxes 3 this month.

Subject: Re: [H] Odd CPU issue
If you've had experience of several bad CPU's then you must be a system
builder with hundreds of builds under your belt. I'm just a hobbyist and
have only built 20 or so boxes over the years and I've never even heard
of anyone having a CPU go bad until you said it. Bad mobo's, PSU's,
hardrives, floppies, optical drives, video cards, RAM, fans etc. I've
seen it all with the single exception of the processor. CPU's are by far
the most reliable component of any PC, period. Intel and AMD deserve
great respect for that major accomplishment. Of course static
electricity can kill one pretty easily but that's not "going bad",
that's user error. Somewhere in this area in a land fill is my original
IBM PS/2 486 SX-25 and I'd bet anything that if it were buried
functional with no bent or broken pins it would still run if socketed in
a working box. I really believe that..

I've had experience of several bad CPU. Having said that, and in view
of the tests that the OP has done, BIOS settings are the first place to
check. The other is the CPU psu itself. I've seen bad capacitors
cause the psu to shut down on heavy load but supply power just fine to
a lighter load, ie a CPU that draws less power.
The other suggestion I would make is to check the BIOS beep codes to see
what the beep code means.
