Try removing all the memory from the board, and then power it up. You should
get a beep code indicating no memory present. If it's still silent, then you either
have a defective mb, a bad CPU or a bad power supply. If it beeps, then all of the BIOS
settings,
including memory timings, will be set to their default values. Sometimes this is
the only way to reset an Intel mb after playing around with BIOS settings and
rendering the system unbootable.
I don't understand what you meant by "...swapped each CPU through D865glc
Mboard with same results for all." Do you mean that every CPU you have,
including the one from the non-working D865GBF, works in a different
D865GLC you also have on hand?
The last time this happened to me, it was a bad power supply that wasn't
completely dead, just a deficient 5V line (so the fans still worked).
