Question My pc won't detect my GPU and the fans on my GPU wiggle back and forth but don't do a full rotation. Is my GPU broken or my motherboard?

I recently bought a new motherboard, ram, case, and aio. When I installed the GPU into the new parts, it booted up, but my pc didn't detect my GPU, and my fans would wiggle back and forth every 40 seconds and would never do a full rotation., which was odd because it was previously working fine. I tried downloading drivers from both Nvidia and from device manager, but every time I tried it was not compatible, and device manager was saying that my GPU wasn't plugged in when it was. Is this a problem with my motherboard or my GPU, or could this be an issue with the cables from my psu to GPU. If it is an issue with the GPU, what could have caused it to break since it was working fine before?
