I have laptop HP ProBook 4545s with two ATI graphic. One is HD 7420G, another HD 7650M and use Windows 10.
And I have problem with bluescreen and "VIDEO DXGKRNL FATAL ERROR" message after Windows logo loading. I'm make clean installation of Windows, but it did not help. When I go in safe mode and disable 7650M, I can use my laptop. If install drivers, got black screen after 10 sec and laptop restart. After that I must go again in safe mode to disable 7650M.
