Ok its a good thing you have got a desktop,

There are several options,

-Send it back into the manufacturer and ask them to fix it.

-Buy a new motherboard off E-bay or some other shop or the manufacture.

-Can you bend the pins back yourself? (DON'T SCREW IT UP MORE CAUSE THATS BAD!)

-Are you sure both the processor/s and the motherboard are broken and not just one or the other?
