How to Fix PC Keeps Rebooting Issue [Windows 10/11]

Is your PC stuck in an endless cycle of reboots? That annoying loop where just when you think it’s about to work… BAM! Another restart? Don’t worry — you’re not alone. This guide will help you fix this issue on both Windows 10 and Windows 11. And we’ll make it easy (and maybe even a little bit fun)!

Why Does This Happen?

Before we dive into the fixes, let’s understand what could be going wrong. Your PC might keep rebooting due to:

• Buggy Windows updates
• Problematic drivers
• Overheating components
• Corrupt system files
• Power issues
• Bad RAM or failing hardware

Now let’s tackle the solutions step by step.

1. Disable Automatic Restart

This is the first thing to try. Sometimes, Windows is set to automatically restart in case of a system failure. That can trap you in a loop!

1. Right-click This PC and select Properties.
2. Click Advanced system settings.
3. Under Startup and Recovery, click Settings.
4. Uncheck Automatically restart.
5. Click OK and restart your computer (just once… hopefully!).

2. Boot Into Safe Mode

If your PC is rebooting too fast to do anything, Safe Mode is your best friend. It loads Windows with only the essentials.

1. Hold down the power button to turn off your PC.
2. Turn it back on and just as Windows starts loading, press the power button again to force it off. Do this 3 times. This will trigger Windows Recovery Environment.
3. Click Advanced options > Troubleshoot > Advanced options > Startup Settings.
4. Click Restart.
5. Press 4 to boot into Safe Mode.

Once you’re in Safe Mode, the rebooting should stop. If it does, you’re definitely dealing with a driver, update, or software issue.

3. Uninstall Windows Updates

Sometimes a recent update can mess things up. Let’s roll it back.

1. While in Safe Mode, go to Settings > Windows Update > Update history.
2. Click on Uninstall updates.
3. Choose the most recent update (especially if the issue started after it).
4. Click Uninstall.

Restart the PC to see if things are back to normal.

4. Check for Overheating

When your CPU or GPU gets too hot, your PC might reboot to protect its components. Time to check the temperature!

You can use free tools like:

• Core Temp
• HWMonitor
• MSI Afterburner

If your system is running above 85°C, it’s too hot!

Try cleaning your fans, making sure you have good airflow, or even replacing thermal paste if you’re feeling techy.

5. Check Drivers

Drivers are like translators between your hardware and Windows. A bad or outdated one can make things go off the rails.

In Safe Mode or normal mode if you can access it:

1. Right-click Start and open Device Manager.
2. Look for warning signs — yellow triangles next to devices.
3. Right-click and select Update driver.

Also, visit your PC or motherboard manufacturer’s website to download the latest chipset, graphics, and LAN drivers.

6. Run System File Checker

Damaged system files can mess everything up. Let’s fix them.

1. Open the Command Prompt as Admin.
2. Type: sfc /scannow and hit Enter.
3. Wait. This might take a while. Windows will repair any corrupt files it finds.

If this doesn’t work, try:

DISM /Online /Cleanup-Image /RestoreHealth

7. Check for RAM Issues

If your memory is faulty, weird things can happen — like constant reboots!

Here’s how to check:

1. Type Windows Memory Diagnostic in the start menu and open it.
2. Select Restart now and check for problems.

Windows will then scan your memory after the reboot. If there’s a problem, it’ll let you know.

8. Power Supply Problems

Another sneaky cause — your power supply unit (PSU) may not be delivering stable power.

If your PC reboots randomly even while idle, or especially during gaming or big tasks, your PSU might be the culprit.

To test this:

• Try plugging into a different outlet
• Use a UPS to protect from fluctuations
• If you’re confident, test with another PSU (or have a tech do it)

9. Scan for Viruses

Yes, viruses or malware can also cause random reboots. Especially those nasty ones that dig deep into your system.

Run a full system scan using:

• Windows Defender
• Malwarebytes
• Any trusted antivirus of your choice

Boot into Safe Mode with Networking if you need internet to download a scanner.

10. Reset BIOS/UEFI Settings

Made any overclocking changes? BIOS tweaks? Let’s go back to default and see what happens.

1. Restart the PC and enter BIOS by pressing F2, DEL, or whatever your PC says on the splash screen.
2. Look for Load default settings or Reset to factory.
3. Save and exit.

11. Perform a System Restore

If you’ve got a good restore point set before the madness started, time to go back in time.

1. Boot into Windows Recovery, then go to Troubleshoot > Advanced Options > System Restore.
2. Select a restore point and follow the steps.

This won’t delete your files, just system settings and apps installed after the restore point.

12. Ultimate Option: Reset Windows

If nothing else works, it’s time for a fresh start.

1. Go to Settings > System > Recovery.
2. Select Reset this PC.
3. Choose Keep my files (unless you want a total wipe).

Windows will reinstall itself, fresh and shiny. And hopefully… without all the reboots.

Some Final Tips

• Keep your system updated (but pause updates if one causes trouble!)
• Use a surge protector
• Dust your PC every 3–6 months
• Back up your data regularly in case things go south

Conclusion

A rebooting PC can feel like fighting a never-ending boss battle. But now you’ve got an arsenal of tools and fixes.
