[Cas Beep Beep Im A Jeep]

Well, since the past few days, my cpu has been really high ( 70-100% ) non-stop. I really don't know what to do and this is pretty frustrating because i can't play css at all unless i'm ready to play and freeze every 2 seconds =/.
This is what it looks like : http://i49.tinypic.com/29xy8vo.jpg
So yeah, any help would be really helpful because i really wanna play css again :/.

oh and btw, i use windows 7

Edit : oh btw i'm using a laptop.
