I have a machine that is running XP Pro. The keyboard and mouse does not work at the login screen. I have switched the keyboard and mouse out with working ones so I know it is not these devices. I can get into the bios of the motherboard with the keyboard. I doubt that this machine has had its virus or spyware updated while it was in use. I was told that it just quit working while they were surfing the internet. No recovery disk was created for this machine either. Can someone help me out?
