2) Make sure Microsoft defender is on
3) The BIOS: Version/Date American Megatrends Inc. P1.40, 9/15/2014
(There were 9 missed upgrades)
Upgrade the BIOS to the most recent non-beta BIOS
1.4 > 2.8
ASRock > Z97 Extreme6
Just as an aside, there is a scheduled Windows Update Task to wake the computer. I have it disabled.

Thank you all for the very helpful replies and information. I learned a lot throughout this process. There are clearly a lot of very knowledgeable and helpful people on this forum.
I am tentatively going to mark this issue as solved but I want to give it a couple of more days. My PC has not started on its own and it is not shutting down vs going into sleep mode. I disabled Windows Fast Start which seems to have been the culprit.
Again, thank you all. Hopefully I am not speaking too soon.
I think that the computer IS shut ed down and IS waking up by its own.
- Fast start is a mix of hibernation and fresh start. When it boot it recovers from last section so it will "continue" a previous section. That is why you see many hours on powercfg -lastwake result.
- When it's really shut ed down, any settings on the OS has no effects. The only "alive" hardware is PS (pin 9 - 5VSB -stand by +5V), MB and memory and only BIOS can trigger the PS (pin 16 - PS_ON (soft On/Off)).
To wake up by it's own, it must be a BIOS command:
- Wake On Lan (WOL). To wake by LAN you must send a specific string. Less likely.
- Auto wake on specific time. I would say this may be the one.
On BIOS, under ACPI Configuration you have many settings that can allow the computer to wake up by its own.
As already mentioned, DO a BIOS reset so it returns to its defaults. The MB has a small switch to do it (pag 30 on the manual)

Glad to hear you may have found the problem. I stopped using Fast Start a long time ago when I found out it was causing problems on my computers. One of the first things I do on a new computer is turn off Hibernate . I also make sure it's still off after any Windows updates. If you want to turn off Hibernate, in a elevated command prompt run "powercfg -h off" without the quotes.
No, It is shut ed down.

How Fast Startup Works
Fast Startup combines elements of a cold shutdown and the hibernate feature. When you shut down your computer with Fast Startup enabled, Windows closes all applications and logs off all users, just as in a normal cold shutdown. At this point, Windows is in a state very similar to when it’s freshly booted up: No users have logged in and started programs, but the Windows kernel is loaded and the system session is running. Windows then alerts device drivers that support it to prepare for hibernation, saves the current system state to the hibernation file, and turns off the computer.
When you start the computer again, Windows does not have to reload the kernel, drivers, and system state individually. Instead, it just refreshes your RAM with the loaded image from the hibernation file and delivers you to the login screen. This technique can shave considerable time off your start up.

Fast Startup requires the hiberfil.sys, But you can use hibernation without Fast Startup. Fast Startup with Hibernation is Hybrid Sleep..... kernel in mem with a trickle of power, and the mem image on disk in hiberfil.sys. But hibernation alone is the hibefil.sys on disk, with nothing in mem. Total power off. Power on will load the contents of hiberfi.sys, so it's only a little slower than Fast Startup. With an SSD, both are superfluous. With an HDD spinner, they can have an advantage, with all the caveats that go with it. It's not a perfect scenario. If there is any queezy code when you use Fast Startup, it will still be there when you start. That's why a real cold shutdown/startup is the cleanest with the least chance of error.
