Windows 10: Sudden, uncalled-for restart

I'm new to Windows 10 (pro 64 bit), and I was just reading the newspaper on Google Chrome, with no other user apps running, when suddenly the whole screen went sky blue with white streaks in it, then went black with lots of disk activity, and eventually went into a long reboot, finally bringing me back to Google Chrome on the same page I was reading. I've been using XP for more than 10 years, and I've never seen anything like that. I wondered if it was an automatic Windows Update, so I looked at Update History and didn't find anything with today's date. If, instead of just reading the paper, I had been working on something that needed saving, would I have lost my work? Can anyone tell me what happened?

:)

 

Windows 10 does automatic uncalled for restart within 2 or 3 minutes after starting.

Here are options for managing how updates are installed:

Option 1:

Set your Internet connection as metered:

Option 2:

Use Active Hours and Restart options:

https://www.groovypost.com/howto/managing-windo...

Option 3:

Use Show/Hide Updates tool to block the update:

Is there an option or work around to block updates or hardware drivers that might cause problems?

Yes, Microsoft has released a KB update (KB3073930) that will let users block or hide Windows or driver updates.

You can download it at the following link:

https://support.microsoft.com/en-us/kb/3073930

Option 4:

Press Windows key + R

Type: services.msc

Hit Enter

Scroll down to Windows Update

Select it then right click it

Click Properties

Under the General tab, choose Startup type to DIsabled

Click Stop

Click Apply then OK

Option 5: upgrade to Windows 10 Pro, which lets you pause updates for up to 35 days.

Open Start > Settings > Update & security > Activation

Click the link ‘Go to the store to upgrade or enter a product key’

Click the $99 button to make your purchase (the price might vary by region or depending on the edition you are upgrading from or upgrading to).

Follow the on screen instructions to make your purchase.

Within 5 to 10 minutes, your system will be upgraded to Windows 10 Pro, your personal files, apps and settings preserved.

You won’t get a product key, you get a digital license, which is attached to your Microsoft Account used to make the purchase.

 

Windows 10 does automatic uncalled for restart within 2 or 3 minutes after starting.

After starting Windows 10, going on line and opening webmail, while reading mail the screen goes black, then what appears to be a "normal" restart occurs. Any thoughts?

 

Look at the Events Log. Type in "event" (without quotes) in Cortana search, it will be at the top. You may have had a power spike/surge/blip. Look at the errors log for something pertaining to Kernel.

 

If it were an automatic restart due to an update, it would have been an update from TWO DAYS AGO. That's how long you have to restart the computer before it restarts on its own.

 

It would not do all that blue screen white line jittering on an update.

 

Sure enough, but what does it mean? Must I expect this to happen often now that I'm running Windows 10? Here are the Event details:Log Name: System

Power spikes and surges are unpredictable and should not be construed as inherent to the operating system. The long boot time and the fact it returned you to the Chrome page you were on indicates it did what it should, it recovered. Was your laptop plugged into AC when this happened or were you running on battery? Without any other evidence, I would not assume it to be the OS at fault. That would be highly unusual. I would not do anything to try to fix a problem that really cannot be diagnosed.

As always, a good backup plan should be in place. Never assume nothing will ever happen. Has this happened since your post, or is it a one time event.

Wish there were more I could tell you. Post back if you have any more sudden restarts like that. Although you state it has never happened before, there is always the chance of a hardware problem. Nothing call be ruled in or out at this point.

 

Thanks. I was running a laptop on AC with a battery as backup. It hasn't happened again (yet). It's happened only once, but on the fifth day of my migrating to Windows 10, so that could be once every five days (oof!). It's the same laptop I've used for many years with XP, with only rare problems--blue screens (without automatic recovery) maybe once every three or four years. Should I mark this thread Solved?

 

There is absolutely no connection with the OS you're running and a possible power spike/blip when plugged into AC. If you're satisfied that the Win 10 is not randomly causing a power outage, then by all means mark it solved. Otherwise, leave it open.....maybe someone else has a solution.

P.S. - Is your AC plugged into a surge protector? Power strips are about $18-20, single wall unit about $10.
