Computer shows black screen.

 When I turn on my computer my monitor is completely black and after a minute it turns off. I tired to plug it in with both and HDMI-cable and a DP-cable and it won't display anything. I did found out a trick by accident. If I pull out the PCI-cables out of my GPU, plug in my HDMI-cable into the port on my motherboard. I then turn on the computer until the login menu pops up. Then I turn it off, plug in the PCI-cables again into the GPU, and then I plug the HDMI into my GPU again and it will turn on normally. After that I can plug in my Displayport-cable again with out the screen becming black again and the card is running fine. This is of course a not so optimal solution to the problem so I wonder what the problem is? I've used different drives but it hasn't done anything different.

Try taking out the GPU starting the pc with the iGPU and then turning it off and putting the GPU back in again
