Computer Stuck on Restarting? Causes and Fixes

A computer stuck on the restarting screen is usually finishing an update or struggling with a driver, a connected device or damaged system files. Most cases can be fixed without losing data, as long as you work through the steps in order.

Common causes

• A Windows update in progress. Updates can take a long time, especially on older drives.
• External devices. A USB drive, printer or dock can stop the computer finishing a restart.
• Damaged system files, often after a power cut or an interrupted update.
• Newly installed software or drivers that conflict with Windows.
• Failing hardware, including a failing drive or faulty memory.
• Malware.

Fixes to try, in order

1. Wait 20 to 30 minutes if the drive light is active. An update may still be running.
2. Disconnect every USB device and external drive.
3. Hold the power button to switch off, wait 30 seconds, then start again.
4. If Windows offers recovery options, choose Startup Repair, or start in Safe Mode.
5. In Safe Mode, uninstall recent updates, drivers or programs, or use System Restore.
6. Run sfc /scannow from an administrator command prompt to repair system files.

Protect your data before you reset

Do not reset or reinstall Windows until your files are safe. If the drive clicks, grinds or is very slow, stop and see our guide to protecting your data when a PC won't restart.
