If new VU didnt fix this problem - try checking windows updates for sound driver fix - solved my problem on nforce 2 mob
I don’t know if this is related but whenever i access my storage i instantly ctd i guess it could be the sound from storage is corrupt
man I had that storage CTD problem and support told me to update my sound a graphics drivers, which I did, even though it was obvious that it didnt have anything to do with the price of fish, and it turned out it was longu claws causing the problem!!! >_<
