You might also look in the BIOS and see if there is a keyboard selection for USB connection...if so and if you use the PS2 type connector....then disable the USB keyboard support.

Just make sure that your keyboard support is for what type of keyboard that you are using.

One other thing....the set up files for the keyboard is for the use of a standard US 101 key keyboard. if you are using something other than that it could cause you some issues..
