Hi, i was watching movie yesterday and all of sudden system crashed. tried to reboot it but was not getting display. So i disconnected my graphic card (r9 270) and used inbuilt video card and my old graphic card as well, it worked out well on those and i got display.. worried about my present card r9 amd 270..has it become faulty..when i plug it in all fans are working including cards but no display... i have reinstalled its drivers as well but no success
