Hi, same problem here with the same board, however this board ran fine for 2 years, the problem occured after swapping it out to a different case. Tried everything I could think of, even reflashed the BIOS.. no luck. Even with no hardware in it just processor and ram it won't go beyond a BIOS post... never gets to look for an OS.

I also solved the problem by upgrading to a P55 board since I can't wait for the RMA and I also liked the idea of a 1156 machine for the bedroom where this one was going.
