Posted this somewhere else never got a responce though so I don't know if it will work but I looked it up online and found this.
Well I think you can do this:
1] Open Control Panel and then Device Manager and select/highlight your present keyboard [HP in my case] in the list under "keyboards", of course.
2]Go into "Properties" and click on the "Drivers" tab then click on "Update Driver"
3]Click on "Browse my computer for driver Software" then click on "Let me pick from a list of drivers on my Computer"
4]Highlight the "PC/AT Enhanced PS/2 Keyboard (101/102-Key)" driver in the list and click "Next" to install.
5]Restart the computer
let us know haw it goes
