I ran the free AVG boot disc virus scan on it, and it did not find anything. I also tried running some of the programs from Hiren's boot disc, but only a few worked - most give errors.
I'm at a loss on how to approach this, since of course, when it boots normally, I can't do anything without a mouse and keyboard.
I don't know if it's a virus, but I don't believe it's a hardware problem.
PS: the computer is not frozen. XP loads, and the email program opens and downloads email. It's just the USB ports or mouse and keyboard that don't work.
