hello my psu burnt out recently and after replacng it i noticed that i had no keyboard input. on checking device manager in keyboard it says unknown and windows tries to install 'unknown' keyboard but says cannot install.
I've tried uninstalling the keyboard from device manager disconnecting it and restarting it then plugging back in but no joy.
its a logitech keyboard which as i know uses microsofts drivers as i have never had to install it before but i did try usng a microsoft keyboard driver but with no joy.

i tried to repaired with xp disk but i haven't got a clue what to do there!

:thumbsup:

Your keyboard port probably shorted out, and is damaged. You may need to go buy a USB keyboard or replace the motherboard. When power supplies go haywire issues like this can happen.

Go buy a USB keyboard first and see if it works, if it doesn't then go buy a new motherboard.

it is a usb keyboard and i've tried it in differant usb ports and nothing . i've also tried the keyboard on another computer and it worked fine.
windows tries to install a usb reciever but i just get a yellow explanation mark next to it.
