Re: Server nightmare

Sooooooooo, I noticed today in my power supply manual that if the board is 
drawing too LITTLE power then the power supply will cut and lock. I plugged 
in a drive and everything spun up, but still no post....
This is progress though - at least I have power on the board which will 
allow me to use a post diag card to see how far along the mb is getting 
through startup before failure. Anyone have a pci post diag card they'd be 
interested in renting out for a night? Unfortunately this board is built 
with no startup beeps.
