Thats very odd after what you said in your first post, look near the vga/dvi port and look at the capacitors from a safe distance.
If they seem kind of white/brownish type color and has bad smell to it...
Your best off chucking the mobo into a recycling bin and getting it disposed of properly.
Check near his pci-e connectors for anything out of the ordinary and check south brige on the mobo and see if you see any sort of damages.
If it looks dead, don't risk that second good cpu in there by trying to make it functional again.
