I don't know what my friend did to this computer. I'm trying to help him fix this problem. First of all, when I first turned in his computer it shows me you can start the computer on safe boot mode, network mode and those stuff right? So I started the computer off safe boot mode but when it loads to the windows screen it automatically restarts the computer. This is windows xp btw. So i reinstalled the computer, everything is done reformatting and stuff. But when i get to the windows part where it continues to install stuff into my computer. It still automatically restarts. (The part where windows installation screen starts)
