I have a problem with my AMD hardware. During gaming, the system shuts down. I checked all the forums on this topic but nothing helped me. I still can not play because at the load the system simply turns off.
Often at startup I have a message that the card is not supported by UEFI and automatically in the BIOS turns on CSM compatibility.

Hello, i had the same problem, try turning off Resizable bar in bios, if its not helping, try to manually overclock your card in the amd Software, lowe4 down the voltage a little bit, set the gpu limit to +15% and set a max gpu clock speed.
Deactivating rBar fixed my issue
Please see this thread to start with: SAM - how it is enabled
The important thing is to have an updated BIOS, CSM disabled, UEFI enabled and an updated chipset driver for SAM to be fully functional and You need at least the following:
CPU: AMD Ryzen 5000 series or AMD Ryzen 3000 series (excluding Ryzen 5 3400G and Ryzen 3 3200G)
Motherboard: AMD 500 series.
Graphic card from RX600 series .
If not then turn it off in BIOS settings.
