I have a MacBook Pro 15inch Retina (mid 2015), by a research I might have a AMD R9 series 270X or 370X. I formatted the laptop and bought and installed windows 10 Pro and now I cannot install drivers for the card. It gives error "Error 173 - AMD Installer Cannot Continue Since AMD Graphics Hardware Was Not Found." I have opened the laptop and changed the thermal paste, very gently. Has my card died and how can I check if it is?
