Given your experience this may be telling you to suck eggs but just in
case:

1; IMHO if the mobo won't even try to boot an attached, formatted drive
with a proven working operating system on it, then the mobo is broken
and should be returned. Ditto if the PROM cannot be reliably accessed.

2: You could try putting things in different slots (or even just
resetting them in their current slots if you haven't already

3: Could this be some kind of Windows/TPM crap?

4: Do you have a working Windows bootable disk to try with?

5: Is the RAM definitely compatible with the MOBO?

6: Is the power supply definitely big enough?

And that's all I have :-) Good luck!

Regards, K.
