[oclug] Repairs

I think the first thing to try is to make sure all power supply
connectors to the mobo are properly seated.  I have seen similar
behaviour if the 4-pin processor power is not plugged in or is loose.
This is a 4-pin square connector on the mobo from the power supply and
usually has 2 black and 2 yellow wires to it.  IF that is plugged in and
reseating doesn't help, try removing and reseating the bigger atx (22 or
24pin) power connecter to the mobo.

cheers!
