About two months ago I had first noticed a problem with my RX 580 when I downloaded PUBG and accidentally turned up a setting which overloaded my GPU causing it to black screen me. After I had solved that problem there was instances where every couple of days while playing Escape from Tarkov ( I could run this game perfectly fine before the PUBG mishap) my monitor would black screen and I would need to take several hours before it even ran again (I didn't know at the time but it was due to the fact that my GPU would simply turn itself off) and when it did run again, every game I opened would run at less than 1 fps ( I counted) sometimes even taking up to a minute to render 1 frame. My solution to this issue was to unplug the PCI-E cable that connects it to the Power Supply and reconnect it, simple as that, and it worked. Up until yesterday while I was playing GTA V. It black screened as normal but this time I realized that my GPU had entirely stopped working. So I figured this was the same as the rest of the times and unplugged the PCI-E cable and plugged it back in. Well ever since then, my GPU has not turned back on. I've tried putting the GPU in the secondary motherboard slot, to no avail. I've looked in my drivers to see if I've missed any new ones, tried different PCI-E cables, considered the fact that it might be a PSU issue and checked my output compared to my need and it is quite adequate. My specs are AMD Ryzen 5 3600 CPU, 32 Gb of Corsair Vengeance RAM, AMD RX 580, EVGA 650 W PSU, B550-F GAMING ROG STRIX motherboard.
