Hello. I have problems with my graphic driver for my rx 550, 2gb version. I cannot install lastest driver version. I receive errors like "no amd graphic driver is installed", with last driver, my pc got blue screen. Now i use 18.5.2, and it works properly, but some games doesn t work with it (for example, fortnite) and games seems a little bit laggy. What can i do? Windows 10 pro.
