COD4 problem

[metroid]

I tried installing COD4 on my comp and when I tried to start multiplayer it just shows the logo screen on my desktop then it says the program encountered a error. I tried to go into safe mode for SP but then the screen appears then disappears normally but then the game never starts?

Updated my Nvidia GeForce graphic card drivers and reinstalled COD4 and same thing happens still.

Whats my issue?
My comp's easily ready to play the game it is built for gaming.
