Testing CPU & Mainboard

I have a few non-functioning mobo/cpu pairs. Question is which
component of each pair (mobo-cpu) is defective? I assume a mobo will
not function without a cpu, hence can I assume a POST diags card is no
good without a known good CPU? If so this reduces us to swapping CPUs
& mobos until a good pair produce a POST/BIOS screen:

1) If I fit a known good CPU in a suspect mobo will the CPU definitely
or possible be damaged?
2) If I fit a suspect CPU into a known good mobo will the same risk be
run?

Anything's possible. Particularly if the mobo juices the cpu with too
much voltage.

Got any manuals for the mobo's? If a cpu is "supported", I'd guess
the probability of damage to the cpu is very close to zero, all
other things being equal.

Sometimes cpu's in the same family and voltage range are released
after the manual's print date. These are generally OK if you know
what they are.

You mean 'will it burn the mobo up?' or somesuch? I think not.

You didn't buy 14 or 23 such devices inna box for around
"a dollar-two-ninety-eight" didja? :-)
