I was online this a.m. and all of a sudden a window came up on the desktop saying, "restarting". I checked my updates file and nothing had been updated by windows. Where do I look to find out what was going on. Like what was updated that required a restart? Thanks.
 


Solution
Are these complete loss of power restarts? Temperature issues very rarely cause reboots, usually suffer thermal throttling long before a shut down.

Usually this type of issue is PSU related. I have no idea about the quality of PSU. Please check the health of your PSU.
You can look in the System log and filter for User32 events to see what restarted your system.
 


I went to system in settings - filtered as suggested. Did a search on system log. Where do I go to get the system log. Duh me again.
 


I looked in maintenance for reliability settings - it did say Dell update which I guess would require a restart. I did not receive a notification from Dell that they were updating something. Just a restart. I guess I'll go with that. Thanks for the help.
 


Went to event viewer but a bit over my head. I see the Dell digital download entry. I highlighted that and filtered for user 32 events but again, not sure what I'm seeing. Is this something that I should worry about? Thanks.
 


Screenshots would probably be useful to responders. Can you provide some?

I managed to get this snip - perhaps it will tell why.

so: Event Source, user32? I'm not sure about navigating thru all these windows that come up. I'll try again.
 


You can also open a powershell prompt and copy and paste this. Should give you any less common shutdown (or non-user initiated ) shutdowns.

Get-EventLog -LogName System -Source User32 -newest 100 | ? { $_.Message -notlike "*explorer.exe*" -and $_.Message -notlike "*winlogon.exe*" }
 


Try the new cross-platform PowerShell Installing PowerShell - PowerShell

PS C:\Users\PV> Get-EventLog -LogName System -Source User32 -newest 100 | ? { $_.Message -notlike "*explorer.exe*" -and $_.Message -notlike "*winlogon.exe*" }

This is what came up. No mention of 12/22 when the event took place. I copied paste into power shell and copied paste for here.
 


I'll try doing it according to the diagram. Again where do I find "system logs" -- I went into the "manage" file but don't see logs mentioned. While I don't see any problem with the pc, this does have me concerned. No one has indicated a problem from this symptom. It does show a Dell update so I keep thinking that is it. Thanks.
 


Just found what diagram shows: looks like a shutdown was initiated but gives no clue as to why. As you can read in annotation. Thanks again.

Look up the error code in the photo. Those codes usually provide at least some information.

Looks to be something that a lot of users experience. I don't see it as a problem - just an inconvenience especially if you are in the middle of something crucial. Thanks for all help.
