Me and my dad were installing some lights in the garage, wiggld some wired and the breaker flipped for the downstairs. When we turn on his computer, everything looks fine, untill it gets to a specific screen http://i.stack.imgur.com/IDLox.jpg that isn't my picture, but exact same problem, different situation. After 30 seconds it goes black for half a send and goes back to this screen, and it just loops like this.
