Performace pro crashed my laptop

Last night I tried to run performance pro on my laptop. at one point it said it was going to restart my pc so it could finish fixing this and that. it got to "scanning and repairing drive c" 10% complete then it just sat there. after waiting about an hour and a half I decided it was ridiculous so I restarted it. it went back to scanning again, got to 10% complete then just sat there again. This time I shut it down took the battery out and tried it again, no luck. I'm so damn frustrated! My computer was working fine and in an effort to make it better I get this crap. Any help out there?
