System keeps restarting after 5 to 10 minutes

Hello Shubham,

Thank you for your interest in Windows 10!

Do you get any error message when the system restarts?

I understand your system keeps rebooting repeatedly after 5 to 10 minutes. In order to troubleshoot the issue, I would suggest you to try the following methods and check if the issue persists.

Method 1:

To diagnose whether this issue occurs in
“Safe Mode”, let’s reboot the computer in safe mode and check if the issue appears there as well.

Safe mode is a diagnostic mode for Windows that starts your computer in a limited state. Only the basic files and drivers necessary to run Windows are started. This helps us in identifying whether the issue is due to some
third party programs conflict. The word Safe mode appear in the concern of your monitor to identify which windows mode you are using.

Follow the steps given below and check if that helps.

• 
  Type settings in search and click on Settings.
  
• 
  Click Update and recovery, and then tap or
  click Recovery.
  
• 
  Under Advanced startup, tap or click Restart now.
  
• 
  Once your PC restarts, on the Choose an option screen, tap or click
  Troubleshoot.
  
• 
  If you don't see the Startup Settings option, tap or click
  advanced options.
  
• 
  Tap or click Startup Settings.
  
• 
  Tap or click Restart.
  
• 
  On the Startup Settings screen, choose the
  Safe Mode.
  
• 
  Sign in to your PC with a user account that has
  administrator rights.
  

If the issue does not exist, try to clean boot the system.

Placing your system in Clean Boot state helps in identifying if any third party applications or startup items are causing the issue. You need to follow the steps from the article mentioned below to perform a Clean Boot.

How to perform a clean boot in Windows

[Steps for Windows 8.1 hold for Windows 10 systems]

Note: Refer "How to reset the computer to start normally after clean boot troubleshooting" to reset the computer to start as normal after troubleshooting.

If the issue still exists, try the next method.

Method 2:

Try to run a System File Checker (SFC) scan to check for any file corruption.
SFC scan will scan for corrupt system files on the computer and repair them.

• Press Windows key + X, click Command Prompt (Admin).
• In the Command Prompt, type the following command, and then press ENTER:
  
  sfc /scannow

Hope this information is helpful. Do let us know if you need any further assistance, we'll be glad to assist you.
