Android

I downloaded this app, and it messed my whole droid up. Everything seems to be working except for the screen, it is black. Tried the whole hard and soft reset, problem is, i cant see my screen. There has to be a way to plug this phone into a computer, wipe it clean, and reinstall factory software the way that it was bought. Can't find anything on google about it, but I know there has to be a way. Help is very much appreciated, I can't even have phone sex with my girl anymore. Thanks in advance.
