Last night I tried a clean installation from 17.9.1 to 17.10.1 AMD drivers through the amd settings menu . After the first automated reboot everything worked except the display . After 30 mins of a black screen I restarted my computer manually and now it turns on for 5 seconds and then turns off again . It keeps repeating the cycle by itself . Has anyone had the same problem before ? My guess is that the uninstallation process of the clean install deleted even the most basic graphics drivers and I get no display at all .
