Motherboard failureFollow

So last night I tried to move a motherboard from one desktop into a new case, with a new power supply. Unfortunately, I think the power supply was bad, because shortly after hooking everything up properly the smell of ozone came out of the case and I unplugged it immediately. Now, even when I hook the motherboard up to the old PSU (with all of its old components, so I know the PSU is powerful enough), the power light on the motherboard comes on, but nothing will power up - there's no beeps, no lights, and no fans or drives spin up. Am I basically looking at a shot motherboard at this point, or is there some magic fix within reach (not likely)? Thanks.
