I just got a Chaintech AV-512 sound card. When I try and install the drivers on the CD, rundll32 starts using 95+ CPU cycles and my mouse freezes. When I try and install the latest CMI8738 ones off the web site, my CPU load stays normal but the mouse still freezes. In both cases, the driver installation finishes copying files but gets stuck on the "waiting for audio driver to become available" step. Do I need to uninstall my nVidia drivers for my onboard AC'97 sound to install these drivers? Or is the problem something else? Thanks.
