I know this is a rap forum, but does anyone have any idea on how to fix this?
I got Counterstrike Source and when I play it, it lags like a bitch. Not like HAFL Lag for me but when I play, it lags 24/7 not even a second with no lag. I move with my mouse to aim, and it takes like 3 seconds to go to the spot and it seems like im running in place.

Is it the graphics card or w/e?

When i play CS 1.6 its fine, but Source it like a bitch.
