Hello, I have just recently build a computer and I'm having some problems with it. It would freeze when I leave the computer alone and that's it. It's fine when I'm using it. I will sometimes leave music on, but then suddenly hear it stop when I leave it alone. Can someone help me? Everything in my computer is brandnew except for the two Harddrives and Cd and dvd rom. At first I thought it was the screen saver, but it still froze. I think my monitor has a hibernation mode, but I don't know how to turn that off. Specs. Windows XP Service Pack 2.
