is it possible that you "auto-updated" to SP2 maybe?
I have been having problems with my computer over the last week. My computer has gotten progressively slower over the last week and continues to get worse. It takes forever for the computer to do anything. Also, when the computer boots up at this point, it displays the Microsoft logo and just says XP, it no longer says XP PRO, and there are no longer any copyrights listed. Could this be a virus? Has anyone else run into this problem? Any help would be greatly appreciated.
