Keyboard No Worky

I don't know what happened but my keyboard stopped working.  For a brief moment when the computer is starting, I see a message that I have no keyboard.  I used a spare and restarted but that too doesn't get detected.  Help me /comp/.  :(

usb keyboards don't have bizarre limits on what keys you can press and when. They have their uses. For normal typing they're kind of stupid but if you're gaming it's good to have USB
