Question Only monitor working at a time

So, I woke up this morning and only one of my monitors was displaying.
My other monitor was saying displayport not working, etc
I reseated my graphics card, RAM, tried different cables.
Nothing.
Then I turned my computer back on and noticed that my bios was actually popping up fine on the monitor that was supposedly undetectable.
So, I unplugged the HDMI and just left my display monitor running and it popped up just fine on Windows.
I plugged my HDMI cable back in for my other monitor and then the display port monitor turned off and was no longer detectable again.
So it's only allowing one monitor to work at a time.
Any ideas?
