Looks like my P35 died somehow. I had it on open air benching just last week and it was fine, and it has been off since then. Decided to put it into PC #2 in place of the DK X48, got everything connected, powered it on and...nothing. The POST code LEDs don't even light up. Cleared CMOS, disconnected everything, used a different CPU, blah blah. It's a goner. Time for an RMA I suppose.
