You could attempt to uninstall the driver for the keyboard from device manager and then reboot. From there it should re-install. If that doesn't work, maybe take a look at the manufacturer's website to see if they have a driver for the keyboard for XP. If worse comes to worse, you could try remapping the keyboard.
