HELP!! controls stopped working!

I'm sitting here typing a paper and my illuminated keyboard goes out when its set to be on all the time. I try adjusting it manually and it won't let me. My controls also stopped working on adjusting brightness. When I click increase volume, it brings up my dashboard.

I did not spill anything on my laptop. It just started happening out of nowhere. I also tried restating and its still not working.

 

every key works except the for the top row with the functions. I also can no longer open system preferences.

 

i restarted once again and am now allowed to access system preferences. If i hold fn and then hit a function, it will work (except for keyboard illumination, it just makes an error sound.) However if i dont hold fn, the forward and mute button darken the screen except for the window you are using, the lower volume button slides the window you have up off to the side, the raise volume button brings up the dashboard, and all the other top row buttons dont work.
