I am working on an HP laptop running XP pro that is driving me crazy. It boots up normally to the Login screen where it is asking you to use Crtl+Alt+del to log in. If you log in at that time then the computer continues to boot correctly. But, if you step away for a few minutes and leave the computer without logging in, the screen goes to black (but with backlight on) and no cursor and frozen. can not do anything. I tried system restore back before the problem started without any luck. it seems fine in safe mode. I scanned it for viruses. I changed power and screen saver settings to never. Please help before I through this out the window.
