hardware problem PC dying before BIOS

[Slipparino]

Sooo long story short, my pc died while I'm playing a game. After trial and error we figure put its the gpu, so I replace the gpu with a 1060gtx and get a new motherboard. With both those installed; I turn it on and the computer, fans spin lights light up, and it immediately turns off. After trying many things I currently have the motherboard out with only the CPU, heat syn, and RAM installed; along with the 20 pin, cpu 8 pin, and the cord from the case for the power button plugged into the motherboard, only for the same thing to happen.

Specs

CPU - i7 6700
Heat synch - stock intel (with the annoying push pins)
Power supply - 650w sliver 
Motherboard - Z370 Aoruos gaming wifi gaming motherboard [LGA 1151] 

OS - windows 10 64 bit

 

=-= These parts are not plugged in =-=

GPU - GTX 1060 gigabyte

Fans - just 2 case fans

Hard drive - 1T 

 

Anything else you wise people need to know just ask me and Ill tell you what I can
