I've checked the bios, task scheduler, power settings. I can'y figure out why it is booting up every day at 3am. I can replicate by changing the clock to just befor 3am and then shutdown. I am lost.
Any idea's?
It has to be the auto boot is set in the BIOS. Go back over the BIOS again and look closely for this. It can be labeled differently in different BIOS (or UEFI BIOS) so I can't give you exact instructions.
I've looked three times, there is a USB wake support, but no other setting. My wife looked too. She does desktop support, and I do network support. So it's not like we don't know what we are doing. I even updated the version of bios from a09 to a15.
Thanks for the reply.
Hello Hd78glide,
You might also double check your wake source event viewer log using the tutorial below to see if it may ID what the culprit may be that is waking the computer.

Hope this helps, :)

It's more than likely a wind-up by Microsoft programming geeks!
When you install Windows all the services for running disk-defrag, system backup etc
- are set to run at 2 or 3am by default.
I would check those first!
If you are very very very sure it was shutdown..... so win7 isn't running at all, it must be an external source.
Because it happens always at 3am and because changing your bios-time can be used to trigger it again, it can't be a real external event such as wake-on-lan, wake-on-usb.
Something is monitoring your BIOS clock and powers pc on if it's at 3am.
Who can read the bios clock if no operating system is runnig???? Answer: The BIOS itself (if not powered off)
In Win 7 Power options
> "Power Plan" > "Advanced settings"
scroll down to "Sleep" > "Allow wake timers"
> Disable 'em
