Computer crashed and now my displayport monitor isnt detected

[svdp12345]

So I was play mirrors edge, when my entire computer crashed out of nowhere (gtx 1080...). Now when I boot up my computer, it only detects my HDMI monitor, but not my displayport one. Please help

Try disconnecting the monitor from power for a minute.

disconnect the hdmi cable from videocard & see the displayport works.
