Windows XP. Keyboard does not work. I attach a different PS2 Keyboard. Still fails. I attach a new USB keyboard; it fails too. At boot there are no messages from the BIOS about a keyboard problem.
Device Manager shows these devices as being installed with no yellow marks (if you do not know what I mean, you should not be responding here).
So the OS recognizes both kinds of keyboards and the drivers are there.
I beleive this means that Windows is corrupt and I should do a repair install (assuming I can get thru that without the keyboard working OR setup.exe loads its own keyboard drivers).
If you have any other ideas (example motherboard problem??) please reply. Reply means what to do to fix the problem. Regarding mobo problems I am dubious that BOTH the usb interface and the PS2 interface on the mobo are bad but I am willing to consider all ideas.
