Hey all, I'm building a computer for my friend, and I've run into a issue with the graphics card and display.

His motherboard, an ASUS z170 a, keeps giving me a red VGA light with or without the gpu (rx480) in. Either way, there seems to be no video output from the computer. The power supply is a EVGA supernova 650 P2, and I'm pretty sure power is not a issue.

Any ideas on what could be wrong?
