I have Radeon HD 6850 Video Card. I have trouble. I can`t run my PC. After starting my PC i see black screen. I try run in safe mode - all ok, but it`s not ok. I tryed to reinstall OS (Windows 10 x64). After OS is installed I try install Video Drivers, but in proccess my screen is blinking and become black and after when i start my PC i get black screen. Why it`s happend? I`m not playing in games, just watch videos. Before that, everything was fine.
