I just bought a Gigabyte GA-Z97P-D3 (online manual here), and it's not receiving power at all. I check the PSU works fine by shorting the 20/24 pins, so that is not a problem, and I have tried removing my graphics card, CPU and RAM, all to no avail.
Is there anything else I can try/do, or an I screwed?
