So when the graphics card is installed into the system, there is no output from either the mobo or GCard. When it's not installed, the motherboard output works fine.

What could be causing this and how can I fix it?

My system is on a Maximus VIII Hero with an i7 6700k and the graphics card I'm trying to install is a gtx 1080. I'm using the HDMI output in both cases.
