So i bought a slightly used RX 480, the card worked at first no problem. But after playing some games, my PC started crashing/restarting multiple times. Now windows won't boot anymore, only when the drivers are uninstalled it boots. So now i have the card disabled in device manager to be able to boot successfully. Luckily the card has still warranty and the guy who sold me the card is helping me so far. It seems really strange that it broke just like that, is RMA the only option or is there any way i can fix this problem myself? Upon googling around, it seems to be a common issue with Radeon cards even on brand new ones! Though RMA'ing, they might give me the RX 580 version they have in stock, cause this card isn't available anymore.
