I have the next problem with a Ryzen 3 2200 G. I already installed Windows 10 Professional version 1903 and everything works ok. When my pc installed the last driver from AMD, it restarts the pc normaly and when windows stars it freezes and my PC starts to reboot. and also I updated my motherboard Bios to the last version. I bougth this Ryzen in september of the last year 2018.
Mother: Asus Rog Strix B350-F Gaming
CPU: Ryzen 3 2200 G
Ram: 8GB G Skill
Power: BitFenix 80 plus
I tried EVERYTHING, I updated the Bios to the last version, I reinstalled my windows, I used DDU to unistall the drivers, I tried with a old drivers version and I also tried with a old version of windows. *default radeon wattman settings have crashed and been restored* this message apeared later to install the drivers. The CPU temperature is normaly. I have never done overclock.
I hope soon help
