On a more serious note (despite my last post, which I deleted), if you had it plugged in while all of this happened, you're probably fucked.

The same thing happened with my Mac a few years ago. There was a thunderstorm happening outside, our house got struck, power went out, corrupted the whole fucking computer to the point where it wouldn't even turn on. The only thing you can really do at this point is get a new computer.
