we ordered all of the parts a few days ago on newegg, specs: GTX 650 ti 2gb, 8gb ram (2 x 4gb Team Dark Series), i5 processor 3.1 ghz lga 1155, ECS p67H2-A2, Seasonic 750 watt power supply, cooler master elite case,

I assembled it and when I tried turning it on the fans spin for about a minute and it doesn't post, I figured we plug a monitor in because maybe it jumps right to bios - no display, I tried both sticks of ram individually, I unplugged everything except the heatsink, mobo, and case fan, still same result, I'm getting crazy because at first I thought it was the 12v connector that I forgot, but it isn't, any ideas what it could be? just hoping we didn't get some DOA parts.

I feel as though it's a hardware issue, I followed all of the instructions and did the same thing I did when I built my rig and my friend's rig, I think it's either power supply or RAM, idk about power supply, bc the heat sink and case fans both spin for a solid second before stopping, I feel as though it's the RAM
