Try a common cure such as unplugging USB devices?
Why the repair install? There might be a clue there.
I am running XP Pro and in trying to do a repair, the computer seems to be stuck in the restart mode. Every time that I try to do a hard boot, it comes up with, "Windows is restarting". I am afraid to go any further as I don't want to lose everything that I have. Any help will be greatly appreciated. Thanks, Bill
