Computer only boots completely on 2nd attempt.

Hey everyone!

So my PC is working fine in all areas except this.
Whenever I go to turn on my PC, I push the power button, and it appears to boot until it hits the post screen, then abruptly shuts off.
On the second power attempt, it boots fully to the windows screen and I have no more issues with it.
But every time I shut the thing off, I have to power it on twice for it to work.
Thoughts?

New build, just put it all together. Here's the specs:
Motherboard: ASUS z170 deluxe
CPU: Intel 17-6700k
GPU: Geforce GT 200 (Soon to be GTX 1070)
PSU: Evga Supernova 650 G2
RAM: 2 X 8G Corsair Vengeance LPX DDR4
Boot Drive: Samsung 950 Pro m.2

I used to have this problem with my PC. It's likely a problem with some bios setting, likely related to an overclock, especially if you did an automatic overclock. If you are overclocking try setting things back to stock speed. Clear your bios to make sure there are no lingering settings. You may also want to try updating your bios if there is a new version out. It took a bios update on my EVGA z170 stinger to fix things for me.
