Hi!
I recently built a PC. It's not my first time building one but this time I'm running into an issue that I can't seem to solve. When I turn on the pc, all the fans spin and light up, but the monitor remains black with no display (the monitor doesn't even turn on). There is a red LED on the bottom of my motherboard that says VGA.
Specs:
Aorus B450 Pro wifi
RX 580
Ryzen 5 3600XT
16gb Corsair Vengeance 3200mhz

What I've tried:

I have tested it with two GPUs and both of them still had the red VGA LED. I called microcenter and they said that my motherboard BIOS should already have been updated because the box is labeled "AMD Ryzen 3000 Desktop Ready".

Another thing I've done is move the graphics cards to different pcie slots. One more thing I did was take out the graphics card completely and plugged the HDMI into the motherboard( still red VGA LED indicator ). Thank you in advance for the help!
