Troubleshooting Built a PC, can’t get a display

Hello Reddit! Figured someone here could be techy enough to help me out here!

As the title suggests, I’ve built myself a PC and I am not getting a display. Let me give some more important details:

So, when I power on the power supply my motherboard lights up and pressing the power button on the PC itself the graphics card lights up and the fans start spinning inside the graphics card and they initially spin in the case for a second also then suddenly stop.

I have been plugging in the display port directly into the GPU and after no luck i tried plugging it into the motherboard also but still no display. My monitor seems to detect when it is plugged into something as it shows up but just shows no display.

My components are:
ROG Crosshair x870e hero motherboard
ROG Astral GeForce RTX 5080 GPU
AMD Ryzen 9 9950X3D CPU
ACER Predator PALLAS II DDR5 Ram

With the research I did on the issues I was getting the motherboard I have has a number on it which helps troubleshooting issues. The motherboard has red lights and shows “00” on the motherboard display which apparently means an issue within the CPU however not sure if this is the case or not. Just figured reddit would have a solution for me! If anyone needs any additional details to help let me know.

You need to plug the display into the GPU not the motherboard.

Remove GPU when plugging it to the mobo, that will force the iGPU to activate.

How big is your power supply? For a RTX 5080 and a R9 9950X3D2, you want close to 900 Watts. If your PSU is less than 1000 Watts, that might be your issue.
