i bought a new system
i5 6600K
gigabyte z170-d3h
16 gb ram
samsung 850 256 gb
sapphire 380 2G
win 10 64bit
when i shut down the system and then press the power button the system boots, shows the windows loading screen and shuts down immediately.
the next time i press the power button to start the system it boots perfectly whiteout any problems

i have tried to switch fast boot on and off and the result is the same
it does not appear when restarting but only when turning the power on
any ideas?

Any warranty on it? If it's done this right out of the box, I would take it back where you got it from. That should be something they should cover.

Depending on a warranty or not, you going in there and messing with things might void that.
