Yesterday I put together my computer parts I bought myself for christmas and it doesn't turn on. I went through the standard check list at least 10 times and I have everything plugged in correctly. I even tested the power supply and that is not the problem. Then I went and returned the motherboard and got a brand new one and the computer still won't do anything. I tried starting it without the video card and with only 1 stick of RAM also. I have a motherboard speaker and it doesn't beep or anything. I am stuck and don't know what to do.
-intel core ivy bridge i5 3.4ghz
-16gb patriot sniper RAM 1600mhz
-240gb Intel 330 series SSD
-Msi H77MA-G43 motherboard
-Zalman z11 Mid tower
-Apevia 700w power supply
-Sapphire radeon HD 6870 1GB
-Cooler master hyper 212 CPU fan
I've checked everything, reinstalled the mobo, even got a new mobo and a new power supply. Still no lights come on or anything. I'm completely lost because I helped my friend built one a few months ago and we had no problems.
