Hi I've just completed a new build but I can't get it to turn on. All lights and fans start for a few seconds then the the lights turn red it and everything shuts of for a second and restarts.

Specs are:
I7 8700k
Gigabyte Gaming 7 z370
Coolermaster 1000w PSU
GTX 1070
16gb vengeance ddr4 4266mhz
Coolermaster mastermind 240
Coolermaster c700p

Thanks in advance!

My son and I just build Z370 with 8700. We power on, everything seems running but monitor show no input signal. It turns out we did not push memory all the way in. We did not hear 2 clicks on first failure. When we take out memories and put in again, we hear 2 click for each module. System power up correctly this time.
 
The motherboard has some led numbers that should display as the motherboard is powering up.
Find the documentation on what the codes mean and you will get some idea on where in the process you are stuck.

It sounds like the motherboard is trying to find a ram setting that will work.
The ram should be starting at a low speed.
The 4266 speed is achieved via xmp settings.
And... it looks like the max supported speed is less at 4133.
You might check with the corsair site and see if your ram is compatible with your motherboard.

Hey I was being an idiot and missed cpu power LOL.

It's not powering in and loads the screen when plugged into the mobo video output but can't get it to load with GPU output...
