Motherboard replaced, keyboard issues

Hey all,
I have a standard Lenovo Thninkpad T61P, i recently had my motherboard replaced on the advice of my school's tech group. I am now having issues with the keybinds in certain programs. Mostly games, but a few others as well. (ie when i use w to move forward it is reading the input as an incrementing digit, each time i press w it things i am moving up the number line, from 1 to 2 to 3, and so on)
I have reinstalled the programs, and tried new ones that i have not had before and the problem continues.
Is this something that replacing the mother board would have caused or is this likely another issue. Any help that can be given would be great, thanks.
Mike

What was the problem before the motherboard was replaced, did it have anything to do with the keyboard?

If there is more than one key that is playing up you need to check the cable connection from your keyboard to the motherboard.

Outside of game use what problems are you having with the keyboard?

Check that you have the keyboard set for the correct language.
