I recently bought a Gigabyte H8M1-S2PV mobo and a evga 600b PSU. I installed everything and as soon as I turn my PSU on, the mobo runs on its own. No led lights on my fpanel and the button doesn't respond. Also I noticed that the mobo sparked around the 24 pin connector. Also it won't boot.

Other specs:
intel I3-4170
Nvidia 750ti
2x4 8gb corsair vengence

Please help!
