Hello.
I am facing a weird problem and I don't think I am the only one who had face such problem.
Yesterday I've installed my two crossfire r9 290 oc tri x. Worked fine till today. Today, I left my PC open to download games and went to school. After returning pressing enter there were no signal. I switched the HDMI cable to the other GPU and it worked. I went to properties-device manager. The second GPU was not detected for some reason. I tried to switch places, none happend. Both of the GPUs works fine it's just the problem not getting detected and I am trying to solve it. Could you please help me?
