I am playing cod 4 online in BDGS server and some foreign server. So, heres the thing the game crashes for no apparent reason, no blue screen, no nothin. It just pauses with a rrrrrrrzzzzz sound and I have to do a hard restart.

I tried the solution of putting a mic in and also trying stereo mix on. The problem seemed to be gone only to be back agian now. It happened before in the Malaysian server while I was playing. The ping is very low so I played on that server. I thought it was the servers problem. but now in BDGS server the game is crashing.
So, can U pros of cod give me any sort of suggestion please. I am wnjoying cod too much to quit now for this silly reason!
