Keyboard and mouse won't work

I booted up my computer this morning (basic E-Machine) and it was fine until I touched the mouse and got static electric shock. It didn't seem to affect the hard drive (?) because it had already automatically established an online connection and that was fine. But the mouse and the keyboard would not respond. I tried rebooting a few times but to no avail.

Is this fixable? Did the electrical charge do something awful to the computer itself?

Your help is much appreciated!
