I have a computer running Windows NT 4.0 SP6 that is giving me some problems. I've had the same keyboard and mouse on the computer for several months and everything has been working fine. This morning when I turned it on, neither the keyboard or the mouse were working at all. I rebooted the computer and was able to navigate the bios using the keyboard, but when I booted into NT, it stopped working once again. I took the keyboard and mouse off the computer and tried them on another computer and they are working properly. I have made no software/hardware changes to this machine since I've had it. Can anyone help me with this? The computer is totally useless without the keyboard. I can't even do CTRL+ALT+Delete!
