im losing this fight with my own computer. stuttering in every game since the Nvidia Graphics Driver update.

USB Audio Device Properties
Device status:
This device cannot start. (Code 10)
{Operation Failed}
The requested operation was unsuccessful.
i tried Device Manager rollback (greyed out), uninstall via Settings (it came back), and installing the older package over teh top (installer said a newer version exists)... how do i get a clean old version and keep it there? every attempt makes me more nervous that i am going to end up with no display driver at all, i would really appreciate a clear, boring, step-by-step order that people actually trust.
