Low FPS?!

I Just woke up this morning, eat, wash up, etc.. then when i play cf and got into the game i was lagging bad. I got a normal ping 90-100, but my fps is 10-20. The only thing i change on the video setting is i think 1100x1400 wide screen and i use to have 30-40 fps. Am I the only one who is having this problem?
