Hi, I recently got a GTX 1080 and when I replaced my 1060 with it, it said [DISPLAY PORT] NO SIGNAL. When I turn on the pc the GPU fans start spinning so I am pretty sure it is getting power and everything. I tried turning off the monitor and pc, waiting 30 seconds, I tried an hdmi cable, I tried a different monitor. Nothing seems to work. I got the 1080 used but I met the guy at his house and he had it plugged into his PC so I saw that everything was working. My pc that I am trying to put it in was also used, but he said that he was using a 3060 in it before he got a new pc and put the 1060 back in for me. So I just kinda figured it would work for me...maybe that was a dumb move i dont know..

If anyone can help me with this that would be greatly appreciated!
