I would make sure you are installing the right driver for the audio card you have, and reinstall it.

Sounds like you need to stick with Vista. Believe me, Windows 7 is just a tab bit better, but you'll have problems with it.

Is there a way to run a Dynex DX-UC104 with vista.

Sounds like you need to make sure your chipset drivers are up to date and all service packs are installed.
Ther is no reason it will not work in vista as it works in windows 7 64bit.So visit your motherboard site to get bios updates and driver updates, then update all through windows update and try to reinstall.
Windows should install a driver for vista.

this is a link for non vista
