Bootcamp WIndows Keyboard and Touchpad not working

I turned on my laptop and realized neither my touchpad nor keyboard was working. using a external mouse and keyboard I found that even under device manager its not recognizing my mouse. it is however recognizing my keyboard. However the only thing that works on my keyboard is the power button. I need to fix this ASAP for school. I've been using bootcamp for a year and this has never happened.
