@Boinkxp: technically speaking I don't remember the model # of the motherboard, and I'd rather not disassemble it at this point. But if nothing else works, I will do that as a last resort, thanks.
@Tiger-Heli: It's Windows XP. Also, I'm not sure what you meant by "- INPUT-USER INTERFACE-UI CANCEL"...
@RandyT: Thanks for the response. I found GhostKey and will try that this evening when I get him and let you know.
Thanks for the help so far.
