Graphics card shutdown

[ExoMarshall]

So i was doing some casual PC work, watching a documentary and browsing the Steam store.
Suddenly the graphics stopped, as in: The card still gets power and and my monitor reacts to the display port being put in the DS slot in the card. but nothing gets shown. 
I am highly confused as to what is wrong with the card. 
Can anyone help? 
Card: Sapphire 390x nitro 8gb 
System: Ryzen setup

What all have you tried? I would reseat the board, pci-e power plugs, smell for burning (on the cables or board itself), replug the graphics cable to the monitor, restart the monitor or try a different one or a tv to see if any of them output.

I have tried different monitors and a tv, none react. I have an old card which i will see if works. How do i reset my MB?

no, he meant reseat. it means taking the card out and putting it back in. it helps if it's not making good contact with the pci-e slot.

Okay, so i managed to get it working. I flashed the motherboard and then it worked. However, i played some fallout 4 today and saw some flickering. Textures that would get stretched out to the extremes, and then the GPU stopped working again. Flashing doesnt work this time...Any suggestions?
