Logic board replacement = no more working keyboard and trackpad in Boot Camp?

I just had my logic board replaced due to the classic NVIDIA failure that has been happening on my version of the Pro. I try to boot into boot camp but my keyboard, mouse, and trackpad all do not work. All my start-up programs load up just fine and the internet works too, just not my keyboard, trackpad, or mouse. Any thoughts as to what I should do? Everything works fine on the Apple side, just not on the XP side of the machine.

Here are my specs...
