Update I left Afterburner uninstalled and tried to update to 19.1.1 from 18.10.1 and have had no issues so far........
Im glad you got that fixed.
I am getting the same bsod. I dont use afterburner, just wattman.
I encounter the crash whenever I try any custom wattman settings while being connected to 2 4k 60hz displays and 1 1440p 144hz display.
If i disconnect 1 or even just lower the resolution of 1 of the 4k ones, i can customize wattman settings at will.
Interesting. When I first encountered the issue I disconnected my 4k tv ,which is my 2nd display along with a 1440p Acer XF270HU as my main, and still has the machine lock up immediately after login. From the little research I did this specific BSOD has plagued AMD GPUs for quite some time. I know that Windows really does not like running multiple displays at different resolutions. Some day maybe MS will get it right. Apple has had apps scale nicely on 4k for a few years now.
