i tried to install the latest drivers. the installation was not successful so i thought it would be a good idea to uninstall the old drivers and reinstall the 15.7.1. drivers again. Actually it was a real bad idea, because my grahpics since then remains undetected.
i already tried to un- and reinstall the drivers several times. every time i tried to install the drivers the installation took only way too short time and the installation protocol was impossible to read (only consisting of signs).
i also tried to uninstall the drivers by using 'ddu' but after reinstallung (old and new) drivers still the graphics card could not be detected. autodetectutiliy, everst and amd gaming evolved also fail to detect my card.
i have really no idea how to solve this problem at this point, so that i'm kindly asking for your help.
