Stock Stereo

My stock stereo randomly turns on when Im driving. It doesn't do anything, and the numbers are all zeros. It doesn't happen when I go over bumps or anything as if its a short, just whenever it wants to. I can't turn it on with the power button at all, and when it is on, none of the buttons are responsive. I have no power to my stock cd changer, either. I'm wondering if there's a wire somewhere with a fuse attached to it thats dead. I've checked all the fuses already, the ones I could find anyway; under the hood and under the dash.

Any suggestions?
