GPU wont run

Aug 25, 2018
My cousin bought himself parts to build a computer. I helped him assemble the parts and everything but when we launch the pc the gpu spins for few seconds and stops.

We launched the pc with internal graphics and downloaded drivers for the gpu, after it was done we restarted the pc and went into bios again.

I have disabled the internal graphics and chose initial display output as PCIe 1 slot where the card is. The problem is the pc boots and i have display image but the fans on the pc dont spin and the pc doesnt recognise the gpu.
