Did you try a complete power-off - including pulling the power cord out - and letting it sit for a minute or 2?
Even if the machine is turned off - but plugged into wall power - certain components are still energized, among them the PS/2 and USB ports - that's how power buttons on keyboards are able to work. The machine isn't truly *off* until you remove the power source. I've seen similar things happen with USB ports - for some reason the machine wouldn't detect any connect USB devices. Neither a Warm reboot nor a "cold" reboot made a difference. Turning it off and pulling the power cord solved the issue. Or at least until it decides to act up again ;) Jacob wrote: > *Okay… this has stumped me for two day.* > > *XP machine.
