This is exactly what happened to my dual 1.25ghz MDD when the processor card fried. Your motherboard is probably still good, but I'd be willing to bet that if you remove the heat sink and processor card, either one or both of your processors will be a little charred. (Or not. Processor failures don't necessarily have to be that catastrophic).
