Windows 8.1 computer shuts down unexpectedly.

Hi Jodi,

First check the event viewer for additional information related to the issue and let us know about the same.

Event logs are special files that record significant events on your computer, such as when a user logs on to the computer or when a program encounters an error. Whenever these types of events occur, Windows records the event in an event log that you can read by using Event Viewer. Advanced users might find the details in event logs helpful when troubleshooting problems with Windows and other programs.

To do the same, please follow these steps:

a) Press the ‘Windows + R’ key on the keyboard.

b) Select Event Viewer.

c) New Event Viewerwindow will popup.

d) On the Left hand side you can see Windows Logs.

e) Click on the Windows Logs.

f) Under Windows Log click on the Application.

g) Now you will able to see the complete error message.

Copy the complete error message and paste it, so we check the complete error message.

Please refer to these steps:

Method 1:

I would suggest you to **** follow these steps to run System Maintenance troubleshooter.

a. PressWindows key + W and type troubleshooting.

b. SelectTroubleshooting.

c. SelectView all on the top left corner.

d. RunSystem Maintenance trouble shooter.

Method 2:

Make sure your PC is up to date

Make sure the latest updates are installed on your PC. For more info on installing updates for your PC, see Windows Update: Frequently asked questions.

Please post with the issue status.

Tried ALL your answers.  Nothing works.  PC is fine for a few days then we go through a day or two of unexpected shutdowns.  Can't even restart.  I press the button.  It may start, it may not.  It might shutdown at any point from that first boot screen to hours and hours later.  The Event Viewer gives NO CLUE as it's full of exactly the same error messages that every one else is getting.

SERIOUSLY MICROSOFT, what are the chances of so many people suddenly all developing the SAME FAULT all in the same period (since Windows 8.1)????????????????

There is a bug in your O/S somewhere.  Surely you can see that???????????????  I have tried all the troubleshooters, all the stuff you've stated, and a whole load more.  GOOGLE IT!!!  There are tons of users with the same issues in the last month!!!!  Guaranteed way to get us all trying LINUX.

Please look deeper into this issue, rather than fobbing us all off with the usual cut & pasted list of possible fixes.

Thanks.  And if you could give us a way to turn off that damn Task Scheduler on our own PC's then that would be nice, too.

UPDATE:  After writing that email I went through all the troubleshooters you suggest.  They were useless.  I did a sfc/scannow and it reported file integrity as 100% perfect.  I re-did the whole list.

THEN I tried something...  I went into the settings and changed the "page file" size from a Windows-managed size to a massive 7GB as a manual setting.  Suddenly the whole machine is quicker and I've yet to have a shutdown.  I will report back if it shutsdown, or if it doesn't.  But I'm wondering if the problem is related to poor management of virtual memory by Win'8.1...  That would explain random shutdowns and inability to store logs, etc, wouldn't it?  Like I say, it may shutdown any minute (I may have just got lucky) but please consider this...  If you have the fault and are reading this, please try it and see if it helps...  So far my PC is so much better!  Bad pagefile management, d'ya think????

Same problem here.  Windows randomly shutting down, etc.  I know PCs very well.  I'm no novice.  Tested everything... It's a Windows 8.1 mess-up.  My power options are set to "Don't let Microsoft think they own my machine therefore do nothing and leave ME to decide what to do with MY PC...  But it definitely seems something to do with the Power settings being messed-up...  Mine seems to think it's coming out of hibernation when that option is most definitely OFF.  But just like Skydrive can't be fully turned off (well, until you use a Group Policy to forbid it, that is), it seems the power settings have a mind of their own, too.  A bit like the task scheduler that has what MS want hard-boiled into it.  It's a disgrace really.  MS seems to think all our PCs belong to them!  Either way, if you could possibly fix something simple like this it would be nice (or make us buy Win 9 just to get something that works???)

Hi,

Page file is what helps keep your computer stable. Although you may think there is enough memory in your computer to handle all the programs it runs, Windows or programs that run on it can exceed that limit, which causes program errors and even system crashes. So increasing the page file might have resolved the issue.

Hi,

If you suspect it has something to do with the power settings, let’s run the power troubleshooter and check if that detects anything.

a) Press '**Windows + W’**key on the

keyboard.

b) In the search box, type ‘Troubleshooting’, and press Enter.

c) Click on ‘**System and Security’**and click on Power. Click on Next to run the troubleshooter.

d) Follow the onscreen instructions to run the troubleshooter.

Also it would be easier for us to understand if you summarize the issue once again.

Please provide us the event log of the time when the computer shuts down.

 In the Event viewer, expand "Windows Logs" > System and post us the logs.
