Hello. When I updated my windows (7 to 10), I didn't had drivers for my videocard and screen was very bad. When I rebooted my PC, I saw black screen, my laptop screen is off, but windows was working and I rebooted my PC with help ALT + F4. When It was rebooted , I saw normal screen and videocard drivers was installed. Driver version is 15.201.1151.1008. But when I want change brightness, screen becomes black again. And when I reboot Windows, I see black screen, but when I change brightness with fn+f6, It becomes normal. Beta version 15.201.1151.1010 already have this problem. What to do? I do not know when at other actions might see a black screen and how I can fix it.
