After many months of black screens, system instability, crashes, blue screens and reboots.
The system has become stable again with 20.5.1+ Win 2004+ WINDOWS QUICK START DISABLED + Freesync off + all Radeon options off.
As I said 1000 times, it was not because of the power supply or any of my hardware.
I suppose that with the next driver the problems will return? I hope not...
The fan curve is default, and ALL AMD SERVICES DEACTIVATED WITH CCLEANER.
I hope it helps someone
EDIT: It seemed that this was the good one ... Well no, the problem has returned .... At AMD they are geniuses and they have invented biodegradable AMD drivers. Processing the RMA. I hope they pay me back and I can buy an NVIDIA. I will never buy anything from these scammers again.
