After installing win10 x64 pro version 21H1 (windows updates are up-to-date) and drivers from MSI website, everything was working fine yesterday. I rebooted a few times and there were no flickering problem. This morning, I rebooted the system and the screen go awry. Downloaded radeon-software-adrenalin-2020-21.9.2-minimalsetup-210920_web from amd website and let it fresh install drivers but it did not fix the flickering problem. Flickers start and continue until I log on to windows. In bios screen flickers continuously. I unistall the radeon software and the flicker problem gone. Bios looks fine. First time encountering this problem. To use this cpu I need to install the drivers but after I install the flickering problem starts. How to solve this?
