Hi, after updating to windows 10 from w7, my ati mobility radeon hd 5000 series stopped working because of an error code 43. The 4200 series works just fine. Updating the drivers doesn't solve the problem, but i can install them manually like in the attached file. However, the configuration is lost at reboot and i still have problems reproducing videos, so i don't know if doing that is making the system use that graphic card. Is there a fix to this? and there is a way to do what i did through only dos commands?
