run cmd.exe as a admin (windows key+x, then type A)
powercfg.exe /LASTWAKE

It should show what told the computer to wake up.

powercfg.exe /WAKETIMER will show OS timers that may be waking your system

you should also check your BIOS setting to make sure you don't have a setting to wake your machine at a particular time/date based on the real time clock. (RTC)

Anything in the Task Scheduler that could cause that?

for the task scheduler, start control panel, search for task scheduler
and look at the log and see if something is running or starting at a predefined time.
I have windows 10 installed and my task scheduler has a task scheduled to run every day at 4:15 pm. It is a User_feed_synchronization task (uploads info to Microsoft for the feedback program)

look for tasks that are running at the time the computer starts up, click the conditions tab and find one
that has "wake the computer to run this task" selected in the power option of the conditions tab for the task.

you can select enable all task history to get it to track and keep a log of what is running or has run.

I think my BIOS also has the option to tell the computer to turn itself on in the morning. I have it turned off in BIOS, I think it was in the power management but I have not looked for it in a long time so I don't remember. (for my system, I just hit the DEL key while booting to get to the settings)

Could be due to your network turning it on, try this:

1) Type into the start menu Network and Sharing Center and open the application.
2) In the top left corner, click Change Adapter Settings
3) Right click your network connection and click on Properties
4) Click Configure
5) Under the Power Management tab uncheck the box that says 'Allow this device to wake the computer'

Its unlikely but its worth a try.

you might also run cmd.exe as a admin (windows key+x, then type A)
powercfg.exe -devicequery wake_armed

my computer shows these devices can wake my machine:
HID Keyboard Device
Standard PS/2 Keyboard
HID-compliant mouse
Intel(R) Ethernet Server Adapter I350-T2

you could have another device or software like special solid state drive software like
Samsung Magician that could be waking your machine to do stuff like garbage collection for the Solid state drive.

if your Ethernet driver can wake the machine, you could even have another machine or device like a xbox that you turn on and it tells the computer to turn on. (unplug the network connection and see if the machine still wakes up)
