My friend bought a second hand motherboard, CPU and ram. MSI z97 Gaming 7, i7 4790 and 32gb Corsair RAM. He put it all together with new 750w PSU, new SSD, new case and my old GTX 760. The motherboard has 3 buttons a on, reset and OC button the on button lights up when the PSU is switched on but cant get the thing to boot, not even any sign of booting. The fans don't spin no more lights come on. I have taken out the GPU and also tried booting with only one stick of RAM and nothing. Can anyone help because I'm puzzled at why the on button on the motherboard lights up but even with minimum hardware it doesn't boot. Thanks in advace
