Recently i had upgraded my system from Windows Vista to Windows 7. After upgrading to Windows 7, i'm not able to play games on my system. Now the problem is that when i try to play the game the sound is slightly messed up. It has a weird crackling or static sound. It is very annoying. I think its some kind of Command and Conquer 3 problem that i had been facing on my pc? It only happens while playing games on my pc. So, can any one tell me that how to resolve Command and Conquer 3 problem on Windows 7? Any one has any idea about it? Kindly help me out to resolve the above problem. Thanks.
