My computer has been shutting off on its own. At first i though it was a virus, but in the middle of a scan the computer will shut off like someone pulled the plug. I looked up my problem and read an old thread that dealt with this same problem. It turned out something was wrong with their hard drive. Well, I downloaded Everest Ultimate Edition hoping it'll tell me what's wrong with the computer... I don't know how to the program. Does anyone know how to use the program and/or how else I could figure out what's wrong?
