My new Gaming pc is having trouble, it doesnt open cod4 into the multiplayer screen, as it is crashing before it even gets there. Everytime i open up cod multiplayer it goes to run then it goes into a black screen and 10 seconds later it crashes and says look online for a solution, is this a firewall problem cause, firewall pops up sometimes when i try to open it and says allowe access and i do that, but it doesnt work, or is it a audio problem? i have tried everything except for the audio sound etc.

Is this a firewall problem? A firewall prompt pops up sometimes when I try to open it and says 'allow access' and I do that, but it doesn't work. Is it a audio problem? I have tried everything except for check my audio configuration, sound, etc.
