Rolling back?
I have had no new one since long!

I sticked to an older driver, the new ones all gave me problems and artifacts with some games. It does all games that I have, flawlessly. More I cannot demand.
Have not touched the graphics driver since long time!
Anyhow, which version is recommended today, I mean: is said to be stable and not known for having many problems? I am on 275.33 currently. The later range from 28x.xx to - 302.xx all caused artifacts when I tried three or four from that range. Latest version I see is 326.xx. But a Beta.
P.S. I have cleaned and removed dust just some weeks ago, just did it again the past hour. All wires disconnected and reconnected, case opened. I still hope that maybe a flock of dust was just shortcutting something, somehow. Had the same issue with a USB port some weeks ago, the whole system did not boot due to a shortcutted USB port. I thought I have a clean system usually. Clean it 2-3 times a year. Others let pass years, with no issues.
