All of AMD's previous drivers and this latest one have been rock solid for me. I'm trying to think back to the last time I had problems and I can't think of any. I think, the only issue I had was with MW5 Mercinaries when it was released and black bars in game with FPS drop. That was back in 2019 and I think was 19.12.2! I had more recently black screen issue and that was my PSU. AMD GPU drivers for the last 3 years for me have been great.
@SPBonzo you might want to start looking into other areas of your rig for problems. Especially if as you say, it has been fine for 2 years then you start to have issues.
