Quote:Had this problem, in my case it's a bit different, I got a 2nd card, and it probably was used for crypto currencies mining. It turn out the bios of the card is modified, so AMD's driver no longer work with it, all I have to do is flash the original bios came from the manufacturer. You guys can find guides online on how to flash GPU bios, for AMD you need ATI flash which can be found here: Download AMD/ATI ATIFlash | TechPowerUp and the original bios of your card can be found on here VGA Bios Collection | TechPowerUp , remember you need the exact one for your card configuration, include series (ARMOR, OC, ROG, etc...), card manufacturer, GPU, memory capacity, memory manufacturer. You can search on google if can't find it on the website linked above. Good luck.
