    Black screen Windows 7 before log in with AMD Radeon HD7800


      Good afternoon


      I've update Windows 7 to the latest version in order to migrate to Windows 10 so as graphic card drivers to 15.7.1 version but now I've a problem. Everytime I try to turn on the PC one black screen appears and nothing happens (this is before log in screen)


      I was looking through internet and forum for possible solutions but none of them works. I listed below what I've tried.


      - I've tried with old drivers and black screen persist

      - I've tried with Windows + P but black screen persist

      - I've tried with another screen but black screen persist

      - I've tried to connect with Teamwiever but computer doesn't start

      - All tests were made with and without catalyst program

      - I've tried to format and install again everything but the problem persist


      I only get to start when I delete drivers from AMD and work with VGA from Windows but this is not a solution because I can't play or do something
