Hello so I have the Gigabyte RX 580 4GB (GV-RX580GAMING-4GD-MI) bought from Ebay, it had no signal once so ever, so i plugged in one of my old cards and got signal that way. The first boot it was around 98 C, so i quickly shut down the system and restarted it, after that it started running properly (40-50 C). I attempted to run a game on the card and it instantly crashed, turns out it crashes under any type of load. Fans work fine, thermal padding and thermal paste is fresh. Card is in perfect-visual condition. What is the problem, and or is it possible to fix this? I'm trying to start gaming but i can't find any card for a reasonable price, so I'm willing to do whatever i can think of to try and fix this card.
did you have a graphic card before this one on this OS? in this case, did you clean old drivers (with DDU) before installing new device?
is it the correct BIOS version? As a rx from ebay could have been tweaked for mining
