I got this card two months ago and I have had three monitors on it and working until today. When I woke up one of my monitors, I have two connected via DVI and one with HDMI, was not detected. It works when I boot and shows the motherboard and windows startup screens but when I logg in it goes into standby and the GPU can't detect it. I have tried to switch the cables and plugg it into different outputs with no result. I am currently running Windows 7. It's one of the DVI monitors that doesn't work. I have tried to reinstall all the drivers and even reinstalled windows with no results. Would appriciate some help/advice.
