screen turns black

[jonathanM]

hello,

 

A little while ago my screen went black after the motherboard boot logo, I tried a lot  of things to fix this problem like:

booting in safe mode and removing drivers, resetting bios, updating bios, updating chipset drivers, sending the GPU back to gigabyte (they found nothing, it worked fine for them), switched video card cable, used a second PSU to power GPU ( bought special adapter for dual PSU) , I tried different drivers from the Nvidia site and I tried using my old GPU (gtx 750 ti) and that video card booted as normal.

But it still doesn't work.

I have no idea what to do now I hope someone has an idea what it can be.

 

system:

ryzen 5 2600

8gb ddr4

gtx 1660

corsair vengeance 550m

MSI tomahawk b450

 

I hope someone can help me with this problem.
