I downloaded something then it was messing up my CP. Everything was slow and then I decided to restart my computer (erasing stuff completely and restarting windows 8) thinking it would restore everything. It started doing it's thing then my little sister accidentally closed it. I put HP automatic repair. Then I closed my laptop to eat. Opened it and says, "Preparing Automatic Repair." Went black then it's says "Diagnosing your PC" then it went black, and it kept doing this on and on about 2 hours now and I'm getting frustrated. What should I do?
