help!! after installing Intel Arc Graphics Windows DCH Driver 31.0.101.5074 Ive had random driver crashes on my streaming PC... fine, Ill just roll it back... except the 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 ppl say its dangerous and other ppl say its the only correct way. i just wanna go back to the driver that worked yesterday. Whats the right sequence??
