Hello,

How to rollback bios on B450 Gaming K4 motherboard? I am experiencing intermittent freezes, CPU is Ryzen 5 1600. Ocassionaly, mostly in 2D, screen will freeze and go black and cold restart will be required to boot PC. It happens both on Windows and Linux. I have already tried different RAM sticks (Corsair and Kingston) and happens with both.
When I bought the board it came with 3.50 bios, after experiencing freezes I have updated to 3.90 thinking it could solve the issue but it didn't.
Now I would like to try rollbacking all the way to 1.80.
