Ok so last night I decided I wanted to clean my laptop so I decided to just reset everything back to factory settings. So I did this http://www.youtube.com/watch?v=h1vDZrWmHg0 but when it got done and started to restart the computer will look like it turning on and then will go to a command prompt screen and it says loading startup or something like that and then it will go blank and begin to restart the process again. So if anyone could help me out and tell me what to do it would be greatly appreciated.
