So things were fine for a week or two. Now the comp just froze, and when I rebooted after the bios screen (asks if I want bios settings or start up device, and goes into windows without input), I get a white screen. So I turn the power off or on five times, and each time I get a black screen after the same point. So it's getting an image from the computer, but not what it should. I'm going crazy, what should I do?
