Windows 10: My PC keeps on restarting on its own when left on idle for more than 15-20minutes?

I recently noticed that my computer has been restarting on its own after the latest windows update + GPU update from NVIDIA. Before it wasn't doing the restarts but right now it always does. I did an upgrade from my old CPU which is an i7700k to a AMD RYZEN 7 5700X paired with a Gskill Trident RAM sticks 8GBS x2 at 3200mhz xmp profile. I did some basic trouble shooting like unplugging everything, uninstalling windows update, checking my events viewer and setting my power options to never shutdown/sleep/restart. I observed that after the latest windows update it keeps on doing the random re

Windows 10 Restarts if Left Idle

Hi Argel,

Thanks for your reply.

In response to your questions:

• As far as I remember, I did not make any changes. (But again, is there a way I can make sure?)
• I was using the balanced plan before. I have left the PC on high performace since last night. So far, there have been no restarts (which is encouraging, since it used to happen every 10 mins or so of being idle).
• Somehow, all my previous restore points seem to have been deleted after I tried to restore to the most recent one!

 

PC restarted by itself when it was idle how can i check why in

Hi, as I said, predicting the relevant event id's for a restart that occurred for unknown reasons is not straightforward. Try searching for 'What is the event id for a restart' for example, and you'll see what I mean.

I can only suggest you inspect the events around the period of interest , looking for a log off, shut down, restart... and if necessary using the link I posted to identify them. Trying to work out why a PC restarted just from the event viewer could be extremely time consuming, depending on the number of events.

If you're lucky and there are few, then it may be feasible to discover something.

First you'd need a list in time order - note that if you simply open the Event Viewer, the reports are categorised,which make tracking something through time impossible. as you know the time period, you could try this:




But easier is to get this free program (title top left) which lists events in order:




Much easier: look at your update history for that day: does it show an update being applied? If so, what is it? Does that update require a restart?

 

Bluetooth still on while idle

Thanks for following the steps. Now, the settings won't take effect if you are only using normal PC idle mode. Normal functionality of Bluetooth and Wi-Fi settings are to stay connected even if PC is idle. With the settings that you have created, we would
suggest that you set your PC to automatically go to Sleep or
Hibernate once idle. In this way, the settings "Allow the computer to turn off this device to save power" should take effect.

To set your PC to automatically go to Sleep or Hibernate when idle, please follow these steps:

• Open Control Panel, set view by: Small
  icons.
• Look for Power Options.
• Click on Change when the computer sleeps on the left pane.
• Set a timer.

Please try it out. Hope it helps. If you have any other concerns, don't hesitate to come back to us.
