HI everyone i am having a problem with call of duty. whenever i try to open it, either single player or multiplayer it goes straight to a black screen and stops responding. i was jus wondering if anyone could help me. just for the record i recently changed my graphics card to the older Radeon 9250 256mb to test it (i did not get any new drivers for this card). I then changed bak to the Radeon 9550 256mb would this switch have nething to do with the crashing?? other games such as World of Warcraft are working fine it seems to be just call of duty...help would be grately appreciated.

it might be your ram or how much memory you got....
im not really i got a weaker graphics card and ram and mine still works and world of warcraft dosent require high graphics to work
