I'm working with a dell optiplex A machine w/ a PII and for some reason when it boots up I can't use the keyboard or mouse. I tried taking the battery off of the motherboard and restarting and then putting it back in and that didn't work. When it goes into the BIOS it says "keyboard error, press CTRL + ALT + ENTER TO ENTER SYSTEM SETUP" which I can't do because the keyboard doesn't work. I have the keyboard setup through PS/2 and tried both ports, didn't work. The mouse was setup through USB and that didn't work either when windows would boot up. I'm thinking the keyboard could be dead because I tried another keyboard via USB but that won't work with the BIOS.
I'm confused as to what to do now? any thoughts?
