Windows XP Mouse & Keyboard freezing

After attempting to research this problem, I have found many other people with the same issue, but no answers yet.

Anyways XP has been working fine, then one day when I restarted the mouse and keyboard wouldn't work at the startup screen (no hardware or software changes were made prior to me starting it up so I'm not sure what caused the problem). Safe mode, repairing, and restoring all have the same issues. I have 2 other operating systems installed (Vista and CentOS) as well as a couple live disks, and the mouse and keyboard work fine with them. I checked the registry and no unusual programs are starting up, and I also deleted the logitech drivers for my mouse and keyboard hoping that windows would use its default drivers during startup, but this didn't help. I need to find a way to repair this issue since I have some irreplaceable programs installed.

Also the mouse is PS2 and the keyboard is USB.
