I have the same as the issue with my Ryzen 3600 on the Asus B350 Prime Plus. The CPU would literally throough your BSOD errors, except the Video one. I cornered the problem to the "CPU Ration Auto" setting. The CPU literally wants me to set 39.5 CPU ration or it will BSOD. The worst part, it will get stuck at 3949mhz on windows all cores and only Ryzen Master can set it back to normal auto-switching CPU speed of between 3.9 to 4199 MHz. is really frustrating as initially the bios I had before ABB run just fine. Dont know what I can do really as I cant afford a B450 now.
