Black screen after installing nvidia drivers

[Vastery]

Im switching from rx 560 to an gtx 1060 and before removing my old gpu I uninstalled the drivers with ddu, after putting my new gpu in I vent straight to nvidias web site to download new drivers. Half way through the installation I heard the plug and unplug windows sound, after that my screen was black(like I disconnected the hdmi cable), waited 15 more minutes and restarted my pc and everything was black but the pc was booting. Tried installing my old gpu in which worked, uninstalled the drivers again, replaced my old gpu with a new one, installed the drivers again and the same happened.
Update: I managed to install the drivers in a Safe mode but when I boot up the computer normally it just black screens again (disconnects hdmi)

Try flashing a new BIOS on the card,if that doesn't help then the card is probably defective.

How do I do that, I dont wanna risk everything since I can still return the card and get my money back, the guy that sold me the card said what drivers he was using and even that didnt help me.

Flashing BIOS is risky,so just return the card.
