My home build PC windows 7 turns itself on during the night.

I have windows updates turned off for now.

dsperber... I do shut it off via the start button etc. And it is bringing itself back on.

Running out of ideas...

I have the same board you do (P8Z77-V Pro, custom build, latest BIOS 2104) and don't have your symptom. But then, I don't normally turn my machine off at all since it doubles as my HTPC and thus is on 24/7.

But you've certainly checked the BIOS to ensure that none of the WAKE options are enabled, right? They're all disabled, right? Specifically, "Power On by RTC" is disabled?

Consider putting the computer to sleep instead of turning it off...
...then use the info in this post to ask the computer what woke it up.

Yes sir completely disabled.

In your first post, you stated:
"disabled everything I could find, but it still turns itself on nightly"
Does this mean that you turned the computer off before leaving work?
Or do you just let the computer go to sleep after a period of inactivity?
If you let it go to sleep, then maybe the info below will help.
If you turn it off, I'm not sure if the commands below will report anything useful.

According to this website...
Powercfg Command-Line Options
...this command:

Code:

powercfg -lastwake

...might tell you:

Reports information about the event that woke the computer from the last sleep transition.

I realize that you have already look into wake on lan, but this command...

Code:

powercfg -devicequery wake_armed

...might still be worth running.

You might also look around in BIOS for settings that wake the computer. I have several computers at the office that are set to turn themselves on each night or after power has been restored. Some retail motherboards do not have BIOS settings that support such power on options.

Ran this one "powercfg -devicequery wake_armed" and got back( HID Keyboard Device HID-compliant mouse)
Will try more later.
