I just got a new motherboard, cpu, ram and m.2. Everything turns on, I get a green light on the motherboard, all fans are spinning, but the only thing that comes up on the display is random colored lines. It won't go into bios which I need to do to install windows 11.

I tried starting by connecting my display through the mother board. This does work, but obviously I still need to get the gpu working. GPU was working fine on my previous computer just yesterday.

Update: After running for a few minutes fully setup by using the motherboard display port, the NVIDIA logo showed up on the bottom right. I tried plugging into the graphics card again and it has now started working. No clue why it is working now, I changed nothing.
