Heyo, so I recently got a used Sapphire r9 280x from ebay. I plugged it into my computer, where it worked but the bios was old, so I tried to update them. I went on to atiflash and found the most recent bios update and installed it. After the installation my computer no longer would display from the card, even though the fans were spinning. It looked to me that my computer completely didn't recognize that a gpu was even plugged in, and could only be launched in safe mode through the on board graphics. I know the computer isnt broken because I put my old gtx 760 back in and it is working completely fine again . But that r9 280x doesnt work at all anymore. Does anyone know whats wrong? I have looked everywhere, but nothing seems to work, is the card just broken?
