Hi, I just upgraded my CPU from 1700X to 3600 using a B450 board.
However, when I tried to play games, it always went black screen like boof, no sound nothing, just black screen every 10 mins of playing.
I tried:
- uninstalling the graphics drivers with DDU and install the latest radeon drivers
- (same as above) installed older drivers
- increase fans speed up to 90% on 65C at wattman
none of this works 
HOWEVER, watching youtube, browsing facebook, idling, etc (not gaming) is perfectly fine.
I tested it with Unity Bedroom demo and the GPU has 79C max temp. I also tried with 90% fan speed and... still black screen!
I'm using DP output and Freesync enabled.
Everything was perfectly fine when I'm using 1700X!!!! This is just wow.
