Gigabyte GA-Z170X-Gaming 5

[MarcinB1990]

I have boot failure when my computer is turned off for a few hours (4 or more). If I turn off my PC and then turn on again within 1 hour everything works great, system is stable. Problem appears always after a couple of hours.
I've replaced my PSU, battery on motherboard and test my processor and memory. I've updated also BIOS to the newest version (F3).
Could anyone help me to resolve my problem?

Thanks for your reply
My configuration is:
Gigabyte GA-Z170X-Gaming 5 EU rev. 1.0 Bios version F3
Processor Intel i5 6600K revision R0
Memory G.Skill Ripjaws V 3200Mhz 2x4GB
SSD Samsung Pro 840
2x WD Red 1TB
GPU Asus Strix 980
Windows 10

All I did is change multiplier to 40x and enable XMP in memory section.

try slowing memory down to 3200 or enable xmp1 and see how it works. I have the same mb, cpu and ram  running at ddram 4 3200. no problems.

I did not OC my memory, I've just enabled XMP and set CPU multiplier to 40x.
What BIOS version do you have?

[autotech]

F3 which is the latest you can get for our board.

Did you OC your processor? If yes, what are your settings? Did you changed voltage and multiplier or maybe only a multiplier?
