after installing VIA KN400/KM400 16.01.18 (Windows 98/ME) Ive had a black screen after login on my home-built PC... fine, Ill just roll it back. except teh Roll Back Driver button is greyed out, and when i uninstalled it Windows put a driver back on its own... i keep getting this:

USB Audio Device Properties
Device status:
This device cannot start. (Code 10)
{Operation Failed}
The requested operation was unsuccessful.
ive heard of DDU, but people say its dangerous and other ppl say its the only correct way :/ i just want to go back to the drvier that worked yesterday. whats the right sequence?
