Do a windows repair: Put your XP install cd in your cdrom and configure your bios to boot to CD rom. Hit any key to boot form cd and enter setup. when promted do the windows repair. You will need to reinstall all your hardware drivers but your desktop will remain intact. Rule #1. Never ever ever ever keep folders on the desktop without backing them up!!!! Never run your system with the OS in the same partition on a single hd puter and, as far as I am concerned, always build your system wiht two hd's and always ghost your system! (norton ghost).
