I got Msi z87 gd65, I5-4670k and corsair vengeance 2x4gb 1600mhz and It was working perfectly because I got it from my Friend and he was using it that day. I'm pretty sure I have plugged in everything correct , the fans were running the PC made a beep when I turned it on but then it looked like it was 'some thing like idle' didn't hear anything and no signal on monitor . My gpu was plugged in correctly hdmi cable and in the pci slot. Ram clipped in. When I put my mobo ram and cpu I was using before it worked without a problem
