Hey guys. I'm using a homebuilt machine, and today my computer restarted and now I can't boot to windows. It starts up and posts fine (so not mobo, right?). Sometimes it gets to the windows 7 login screen, and when I try to log in it blue screens quickly Other times it just cycles on boot up to the windows screen and then back to boot up. Then the other scenario is sometimes it boots to windows login, the screen resolution is set to 800x600, and I can't move the mouse or keyboard.
