Windows 10: My Windows 11 PC restarts itself after i leave it unattended

My Windows 11 PC restarts by itself when i left it alone.For example : to eat, or do something for more than 30 minWhen i come back it just restarts by itself even though my windows update is up to date. And there is no pending update available, I've tried turning off the fast startup yet it still doesn't work

Windows 10 crashing when left unattended.

the issue is isolated to unattended side of things you need to back trace your steps to check to see what unattended was receiving or doing while it was disconnecting that cause it to crash.

Problems occur if Windows is receiving update or was caught in cycle and could not unbind itself and or if the internet service connection was interrupted which leave you the end user facing system crash.

 

Windows 11 desktop wakes unattended

My Windows 11 desktop PC wakes from sleep/hibernation unattended about 30 min. after sleep/hibernation.

When I run "powercfg -lastwake" it indicates power button.



Before I replace the power switch and or the power supply is there anything else to look at to resolve this?

 

PC will not restart

I would like to have you run a Clean Boot.

How to perform a Clean Boot.

Warning: Disabling items in Services or Startup may leave your antivirus disabled until the process is ended. For this reason I would suggest that you perform this process off line.

Press the

keys to open Run, then type msconfig in the search box. This will open System Configuration.

If you are prompted for an administrator password or for confirmation, you should enter the password or provide confirmation.

(1) Click/tap on the General tab.

(2) Click/tap on the Selective startup option.

(3) Remove the check mark in the Load startup items check box.





4. Click on the Services tab.

5. Place a check mark in the Hide all Microsoft services check box, this will remove the Microsoft Services from the list but will still be running.

6. Click Disable all, this will remove all of the check marks in the Services list.





7. Click on Apply then OK





Click on Restart in the window that opens.

When the computer is restarted it will boot normally.

If the problem does not continue after the restart please do the following.

8. Divide the number of these startup services and programs by two and you place checks in the first half of these, then restart the computer.

9. If the problem doesn't return in those services and programs remove the checks and place checks in the remaining services and programs and restart the computer.

10. When you find which half the service or program is in go on to the next step.

11. The half which has the service causing this problem remove half of the checks as you did previously to see which half has this service. Do the same for the programs. Restart the computer.

12. If it isn't in the first half of these services and programs, do the same with the last half of the services and programs.

13. Once you have narrowed it down to the last three or four services and programs remove the checks one at a time till you find the service or program at fault.

Once you have found the service or program post it in your topic. Do not take any action until I suggest the next step.
