Hi all,

I have two identical Intel D845GLAD main boards, 2 CPUs, one stick of
working RAM and a reliable PSU. Neither board will post & no beep codes
whatsoever, board A at least switches on and off (Fans kick in), Board B
just sits there like a dead duck.

When CPU B is in Board A, the fans die after 10 seconds; with CPU A the
board sits on happily for hours. Checked thermal paste and chip seating. As
I have no access to a working Intel main board or CPU what can I ascertain
from the difference in behaviour of the processors?

Absolutely nothing is my favoured guess at the moment but glad to be
corrected...
