Crackling Sound Problems

Whenever I see bushes or grass or trees in any game, I get a crackling sound from my speakers. Just wondering how to stop this sound. I think it's the video card but I'm not sure.
I use a GeForce 4 MX 440

Would you happen to have an onboard sound chip? Crackling is common if your CPU is trying to do too many things at once, and with onboard sound, the problem is significantly worse.

yea i guess i do have an onboard sound chip. hmm

You might try lowering some of the graphics; it'll put a lesser strain on yours system.

yup, I used to turn off the sound on GW and listen to my MP3s on my computer while playing.....computer spazzed with the music sound soo i had to turn it off. Try putting less strain on the system
