When i turn on my pc and bios loads i immediately get a black screen but pc still runs. It works only in safe mode or when i disable driver signature enforcement. I tried to run ddu, reinstall the drivers, pause windows updates, hide the driver updates with the windows update hide/show app, i tried to install drivers on the other disk and it runs good for about 30min to 1hour but then i get a black screen, when i restart the pc the same problem occurs. I don't know what to do. Please help!
