My friends computer is giving him some trouble so he asked me to take a look at it. I recently got rid of a virus a month or so back, but now it's messing up again. I turn on the computer, then it just shuts down! It goes to the Microsoft windows xp colored loading screen then just shuts down. It automatically restarts itself and says windows was not properly shut down and tries again. I tried loading in safe mode as well, but the exact same thing happens. If anyone has any tricks or tips to help, it'd be much appreciated.
