How to Fix a Computer That Keeps Restarting – Troubleshooting Guide
Is your computer stuck in a restart loop? It can be frustrating when your PC keeps restarting unexpectedly, interrupting your work or gaming sessions. Luckily, there are several ways to diagnose and fix this issue.
In this guide, we’ll walk you through the best solutions to fix a computer that keeps restarting.
1. Check for Overheating Issues
Excessive heat can cause your computer to restart automatically to prevent hardware damage.
How to Check for Overheating:
Touch your PC case – if it feels too hot, overheating might be the problem.
Use software like HWMonitor or Core Temp to check CPU & GPU temperatures.
Open the case and check if the fans are working properly.
Fix:
Clean dust from fans and vents.
Apply new thermal paste on the CPU.
Ensure proper airflow inside the case.
2. Disable Automatic Restart
Windows automatically restarts when it encounters an error, making troubleshooting difficult.
Steps to Disable Auto Restart:
Press Win + R, type sysdm.cpl, and hit Enter.
Go to the Advanced tab > Click Settings under Startup and Recovery.
Uncheck Automatically restart under System failure.
Click OK and restart your PC.
Now, if an error occurs, you’ll see a Blue Screen of Death (BSOD) instead of an automatic restart.
3. Update Drivers
Outdated or corrupt drivers can cause system instability and restarts.
How to Update Drivers:
Press Win + X and select Device Manager.
Expand Display adapters, Network adapters, and other essential components.
Right-click each and choose Update driver.
Select Search automatically for drivers.
Alternatively, download drivers from your manufacturer’s official website.
4. Check for Windows Updates
Windows updates contain bug fixes that can resolve restart issues.
How to Check for Updates:
Go to Settings > Windows Update.
Click Check for updates and install available updates.
Restart your PC after updating.
5. Scan for Malware and Viruses
Malware infections can cause frequent restarts by corrupting system files.
How to Scan for Malware:
Open Windows Security > Virus & threat protection.
Click Quick Scan or Full Scan.
Use third-party tools like Malwarebytes for an extra layer of security.
If malware is found, remove it and restart your PC.
6. Check for Hardware Issues
Faulty hardware components can trigger random restarts.
How to Diagnose Hardware Issues:
RAM Issues: Run Windows Memory Diagnostic.
Press Win + R, type mdsched.exe, and hit Enter.
Choose Restart now and check for problems.
Power Supply Issues: A failing PSU can cause instability.
Try using a different power supply unit.
If hardware is faulty, consider replacing it.
7. Check System Logs for Errors
Windows logs errors in Event Viewer, which can help diagnose the restart issue.
How to Check System Logs:
Press Win + X and select Event Viewer.
Go to Windows Logs > System.
Look for critical errors and search online for solutions.
8. Run System File Checker (SFC & DISM Commands)
Corrupted system files can cause instability.
Steps to Repair System Files:

Type:
sfc /scannowand press Enter.DISM /Online /Cleanup-Image /RestoreHealthIf issues persist, run:
DISM /Online /Cleanup-Image /RestoreHealth
Let the process complete and restart your PC.

A clean boot helps identify software conflicts.

Press Win + R, type msconfig, and hit Enter.
Go to Services > Check Hide all Microsoft services.
Click Disable all, then go to Startup > Open Task Manager.
Disable unnecessary startup programs and restart your PC.
If the issue stops, enable programs one by one to find the culprit.
10. Reset or Reinstall Windows
If all else fails, resetting or reinstalling Windows may be necessary.
How to Reset Windows:
Go to Settings > System > Recovery.
Click Reset this PC > Choose Keep my files or Remove everything.
Follow on-screen instructions.
If resetting doesn’t help, consider a clean Windows installation.
