Windows 10 PC wakes up randomly in the night

So for the past 2 months or so, my PC has been randomly waking up in the night/ when I'm not around - I have searched the internet for a fix and seemingly tried everything but nothing has worked. The strange thing as that Event Viewer tells me the times this has happened have in at completely random dates and times. For example, the latest time this has happened, Event Viewer says I put my PC to sleep at 23:27:07 on the 21st of the second - which sounds about right - but the wake time is 05:55:39 on the 1st of the forth, (if you didn't see the date I posted this) months into the future!

Anyone know a fix? 

Thanks.

If the Wake Source says “Power Button,” that indicates that the power button on the PC was pressed to wake it up—an action you most likely took yourself.
If the Wake Source says something like “Device–HID-Compliant Mouse (or Keyboard),” that indicates the PC is configured for key presses and mouse movements to wake it.
If the Wake Source lists your network adapter, that indicates your PC is configured so that incoming network activity can wake it up—something that’s useful if you like having your PC go to sleep but still need it available to other network devices at times.
If the Wake Source says “Timer,” it means that a scheduled task woke the computer. The source information usually includes some indication about the task that woke the PC. For example, in the previous screenshot, I can tell that my PC was woken up in order to do a scheduled restart after an update.
You may also see something like “Wake Source: Unknown,” which is a bit more cryptic but at least it tells when the PC was awoken.
