As JMK so eloquently stated:

Have you tried to do a repair installation of Windows XP?

JMK

No I haven't, but I will now.

Note: It locked up a few minutes ago. When I tried a ctrl-alt-delete
reboot, it popped up a box saying "ctfmon.exe was not responding - end
now?", then "explorer.exe was not responding - end now?" I ended them both
and it rebooted.

Thank you,
