WARNING." href="http://forums.nvidia.com/index.php?showtopic=5576">nvmcp.sys.. I thought that this problem was solved, but Calvin just got this with SimCity 4 (not exactly a state of the art game) on his Athlon 64 3200+ on a Chaintech nForce3 board. Basic solution is to either. There is a new (August 23 dated) nVidia Sound driver their "download":
- Get a Creative Labs Audigy. These are better debugged than the onboard audio on an nForce3 board. It costs more, but ultimately less trouble.
- Disable the sound acceleration that the nvmcp.sys provides by running Dxdiag and turning "Sound and Hardware Acceleration to no Acceleration.
- Simtropolis.com amongst other Simcity 4 sites notes that nvmcp.sys causes a BSOD, the recommendation is to remove nVidia driverseverything, delete nvmcp.sys from the entire system, install Directx 9.0c and reinstall (that is, clean install everything).
