I've been searching and searching for a reason for this but I haven't found one so I'm hoping maybe someone here might help. Here is the problem: While playing Bad Company 2 (Only happens during this game, haven't seen it anywhere else), my screen flickers then goes black for all 3D objects. The HUD in game is still there, and it only lasts for about 30 to 90 seconds, but it's hard to enjoy a game while this keeps happening. and it seems to go in and out as I move through the level and then it will stop. There seems to be no pattern to it. Any help is greatly appreciated!
