Never mind. I think I have it figured out. Thanks to anyone who might have helped me.
I am having a terrible time trying to log on to my computer. It was working fine on Thursday, but now I can't log on. When I log on my user account it acts like it is going to my account and then it reboots itself. (it does this on all 4 of the accounts) How can I get even to a start menu or something? I can't get in it at all. By the way, it is a Sony Vaio PCV-RS300 series with Windows XP, Norton 2004. I've even tried the ol' f8 trick to go to safe mode, but mine doesn't list safe mode. It list SM-TOSHIBA DVD-ROM SD-5002,...1st FLOPPY DRIVE,... and PM-WDC WD1200BB-22DAAO. Helpppppppp.
