Bought new gigabyte z97x gaming 3 mobo because my old Intel board not working any more so I bought this board for my 4770k and gpu I'm using is gtx 960 it's working the problem is once I shutdown it won't boot next time I need to remove and insert ram to get boot and I have old ram which is 2gb it works fine no problem but when I use 8gb it won't boot on next time I need to reinsert so I thought it was that ram I bought new corsair vengeance 8gb but that also gave same result please help guys is this mobo issue or my psu??? I'm using zebronics 600 platinum.. Thanks
