Display driver crashes

[dunczr]

I have just installed my COD today, however when i choose a mission and then click 'fly' it then loads. Once it has loaded the display driver crashes and it then displays my desktop background however i can hear the gameplay for example when i hit the space button i can hear the cannon of the aircraft firing but cannot get the visual element of the game to play ! Any ideas ? is it my graphics card ?- GeForce 8600GT ?

Many Thanks,

Duncan
