Windows 10: PC Reboots every night?

A computer on our group reboots every night.

The group policy is set to disable automatic updates (also I don't think there are nightly updates).

There isn't anything in the power settings set to reboot or anything, no scheduled task I can find.
It is set to not go to sleep, only to turn the screen off.

How can I stop the computer from rebooting nightly? Any ideas?

Night Light Setting and Third Monitor.

Hi Reagan,

We would like to ask you some questions in order assist you properly:

• Did Night light work previously on all three monitors?
• Have you made any recent changes to your PC?
• Are you getting an error message on the third monitor regarding Night light?
• Is the third monitor being detected by your PC?
• What troubleshooting steps have you performed so far?

While waiting for your response, we suggest that you try to connect your third monitor to what you are using on the 2 working monitors to see if it is only a loose connection issue.

Regards.

 

PC reboots (no BSOD) on CPU stress

Hi fellow TPU members,

not too long ago, the box my gf's PC was transported in gave way on the stairs. Yes, you got it right, that sent a PC tumbling down a flight of steps alright.

Stuff broke. Also, stuff remained intact somehow.

I bought her a new case, new CPU cooler and we removed the floppy drive, so far so good. But the PC started crashing for no apparent reason, without a BSOD.

I tested:

• Memtest86+, left overnight, 0 errors
• Scanned the HDD for errors, nothing there
• Left FurMark burning up the GFX card and drawing some power, no problems there
• Ran Ubuntu from a Live CD doing nothing special, didn't crash
• Ran OCCT, Linpack, Prime95, all 3 caused reboots within minutes
• Oh, and I disabled "Restart on error" so I'm sure it's not a BSOD.

Now, I can still try and test something CPU intensive on Ubuntu, but my guess is the CPU didn't survive.
Before I do anything drastic like whippin' out the magic wallet and get her a new AMD quad, is there anything I didn't see?
I'm guessing the motherboard could be borkered as well, but can I check that other than replacing the CPU with a working one?
Any suggestions on which proggies I can use from an Ubuntu Live CD to stress the CPU?

 

Windows updates forcibly rebooting my PC at night

I suggest to check the

1. Task Scheduler to disable auto-restart after installing updates:
   
   • Go to Task Scheduler Library/Microsoft/Windows/Update Orchestrator
     
   • disable the task named Reboot.
     

1. Another good place to check is the Group Policy Editor:
   
   • Go to Computer Configuration/Administrative Templates/Windows Components/Windows Update.. and the settings of:
     
   • No auto restart with loggedon users for scheduled automatic updates installations: Enabled
     
2. There is also a place in Windows 10 new settings:
   
   • search Change Active Hours
     
   • click on Restart Options and disable Restart
