keyboard error

my brother unplugged his keyboard while his computer was running and now when it starts up either windows doesnt load (gives "no keyboard or keyboard error") or if it does load, the keyboard AND the mouse don't seem to work.  i have seen some things about shorts and everything on here but both the keyboard and mouse appear to have power (light up) when they are connected but they don't actually work.  to make matters worse he tried this on his other machine as well (the keyboard.. was trying to swap them apparently) and the other machine gives the same error (keyboard not found), loads windows fine, but the mouse works.

are both the mobos fried and worthless? it is a possibility he says that one of the keyboards (which had been plugged into both machines) isn't working properly, so that could be it as well.  Anyway if it is the keyboard controller and not the port, is it possible to have that fixed or is it better to just go get a new mobo.

thanks in advance and sorry for the multiple / confusing questions.

or have you tried this, shutdown the system, and then disconnect both mouse and keyboard
start the system and let it to boot as far it can, and then shutdown it from power button
now hook back both keyboard and mouse and start the system

yeah i took a usb keyboard from one of my other computers and tried it on his and it booted up fine, but the mouse still doesnt work, and the mouse doesnt even light up now. i tried plugging the mouse into the USB port (he was using an adapter) and when i do that the mouse lights up (its a microsoft optical) but it the cursor still doesnt move.

since it did the same on both computers, i think the keyboard is frying the board.
You CAN maybe get around this, by using usb kbd and mouse, or vice versa; it is not guaranteed however, depending on what is bad on the mobo : the input circuits only, or more, so test it if possible

looks like the keyboard was bad, also like the mouse was damaged too may want to test with another usb mouse to make sure. and if you dont feel like replacing the motherboards for the bad ps2 ports, just use usb mice and keyboards
