Ok, im getting that error code at windows boot up. The box says windows starting up, then the computer restarts and goes through the same cycle. I have went to numerous microsoft support site with no avail. This occured directly after installing a SP2 for XP Pro. Do I need to format and re-install, or is there another workaround? The only thing running at startup is Yahoo Messenger and Panda antivirus 2006. Any help would be awesome. Thanks in advance.
