HP Compaq Notebook CQ60-615DX CPU Upgrade

Hello is there a way to upgrade my cpu? I am using Intel Celeron 900 @ 2.20 Ghz 2.19 Ghz. The reason I wanna upgrade is becouse I want to get a little bit more FPS on World of warcraft at the moment the fps is 20 and video settings are on low.When I run WoW my CPU is working on 100%
Can you recommend me good CPU?
Can I also change my video card?
This is my system:
