I have installed everything into my new case and nothing works, then I move my motherboard, GPU, RAM, CPU and PSU into my old case and connect the power button from my new case and it works.
But if I move the motherboard and everything else into my new case and connect all of the wires exactly the same way as before in my new case, it won't work!
Everything is the same from the new case to the old one.
Any help please?
Thanks,
Steve
