When Windows Keeps Restarting
A computer that restarts on its own can be caused by software problems, hardware issues, or both. Here is what to try.
Types of Restart Problems
Random Restarts During Use
The computer restarts unexpectedly while you are working.
Restart Loop
The computer restarts, shows the Windows logo, then restarts again repeatedly.
Restarts After Blue Screen
You see a blue error screen briefly before the computer restarts.
Quick Fixes to Try
Check for Overheating
Overheating causes automatic shutdowns:
- Feel if the computer is hot
- Make sure vents are not blocked
- Clear dust from vents if possible
- Use the computer on a hard, flat surface
Check for Pending Updates
Sometimes restarts are Windows installing updates:
- After restart, open Settings (Windows key + I)
- Go to Windows Update
- Check if updates are installing
- Let updates complete before working
Stopping Automatic Restart After Errors
To see error messages instead of immediate restarts:
- Right-click the Start button
- Click System
- Click Advanced system settings
- Under Startup and Recovery, click Settings
- Uncheck Automatically restart
- Click OK
Breaking the Restart Loop
If stuck in a restart loop:

- Repeat 2-3 times
- Windows should show recovery options
Try Safe Mode

Uninstall Recent Updates
From recovery options:
- Go to Troubleshoot > Advanced options
- Click Uninstall Updates
- Try Uninstall latest quality update first
- Restart and check if the problem is fixed
System Restore
If you have restore points:
- Go to Troubleshoot > Advanced options
- Click System Restore
- Choose a restore point from before the problem started
- Follow the prompts
Checking for Hardware Problems
Check Event Viewer
After a restart:
