So all of a sudden I come home to find that when I boot up my pc no display is showing. I then plug my HDMI cord into my motherboard instead of my graphics card and it works fine. I go into the BIOS and it isn't detecting my graphics card at all even though it had been working fine about 5 hours before. Any ideas?
Motherboard: Asus z170 pro gaming
GPU: Nvidia gtx 770

I did this already and I also tried the other port that my motherboard has still didn't work. Sorry should have said that.
