I just bought a second hand R9 380, it was very stable at first with windows update drivers. When update the drivers "16.11.2", black screen ocours in the login screen of windows 10 Flashed with the new Bios with ATiwinFlash, Same problem. Search for the latest Bios, found the G1 gaming Bios. AtiWinFlash. flashing... took more time than normal... Black Screen! Found that my Card is not G1 gaming one. Restart My PC, no POST, No signal. Bricked :C, tried to use atiflash in DOS in a friend PC with IGP, -i "adapter not found". Lost All hope.
