How to fix Windows 11 when it keeps restarting

0

If Windows 11 decides to restart on its own, you might have a serious problem. You could be cut off from online meetings, lose work progress, or end your gaming session abruptly.

When this happens, you know there is something wrong with your computer. Windows may restart due to overheating components, malware infection, or outdated graphics driver, among other reasons.

If this sounds familiar, keep reading as we’ll walk you through the troubleshooting process.


1. Check your GPU and CPU temperature

If your Windows 11 computer keeps restarting when playing a graphics-intensive video game or using design software, your hardware may be getting too hot. Most of the time, it is the CPU or GPU temperature getting too high and Windows needs to restart the system to protect the hardware.

Usually, the hardware overheats when you are running lots of applications on your computer and using a lot of its resources. You can check the CPU temperature and if it seems cold enough, take a look at the GPU temperature as well.


If you notice your hardware reaching high temperatures as soon as you start your computer, you may be dealing with a faulty cooling system. In this case, you must take it to a professional service and have it repaired to avoid permanent damage.

2. Stop overclocking your computer

If you’ve decided to overclock your computer, you know it’s pushing your RAM, CPU, or GPU hardware beyond its limits. While this may give you better overall performance, it will affect your computer and increase hardware temperature. Especially if you haven’t upgraded the cooling system.

If your system reboots randomly, you should restore it to its original state by uninstalling any overclocking software. If you don’t want to upgrade your hardware, take some time to think about whether overclocking is really worth it.

3. Check the power supply

A faulty power supply that is unable to provide constant voltage can cause your computer to restart on its own. Even if you are using an uninterruptible power supply, your computer may restart due to a faulty UPS or battery.

If you have installed RGB lights and they seem to flicker, this may be a sign that your computer’s power supply has been upgraded as the lights are easily influenced by voltage fluctuations. Before changing the power supply, take a look at its wiring to make sure that a faulty wire is not the reason for Windows 11 rebooting randomly.

4. Make Sure Windows Updates Isn’t the Culprit

Whenever Windows 11 requests an update, you have the option to schedule it. As such, your PC may be rebooting to install updates.

Luckily, you can manually install pending updates or stop Windows 11 updates to prevent automatic restarts of your system.

5. Scan your computer

If your computer keeps freezing and crashing, in addition to rebooting on its own, you may be dealing with a malware infection. Luckily, you can use Windows 11’s built-in tools to scan your computer. Here’s how:

  1. Open the Settings menu.
  2. Go to Privacy and Security > Windows Security > Virus & Threat Protection.
  3. Click on Scan options.
  4. You can select Quick Scan if you are in a hurry, but Full Scan will review all files and programs running on your hard drive.

Once Windows has completed the scan, it will notify you of any malware detected and let you know if the infected file has been deleted or quarantined.

6. Update graphics driver

Running an outdated graphics driver will cause all sorts of problems, including restarting your computer on its own. You can use Device Manager to update it to the latest version and fix the problem.

Hurry Win + X to display the Start menu and select Device Manager. Then extend the Screenshot taken list, right-click the correct driver and select Update Driver. In the pop-up window, select Automatically search for driversand Windows will check for and install all available updates.

Sometimes you’ll see more than one driver, especially if your PC has both an integrated GPU and an independent GPU. As such, you can update the drivers for the CPU you’re currently using or update them all to ensure your active GPU is up to date.

If that doesn’t work, search online for your GPU manufacturer and download the drivers for your GPU.

7. Run a CHKDSK scan

Windows 11 may restart randomly due to a failed storage sector that prevents your system from communicating with subcomponents. You can try to fix it by running a CHKDSK scan.

To do this, press Win + S and type “Command Prompt”, but don’t press Enter. Instead, right-click on the search result and select Execute as administrator.

Once it is open, run it chkdsk /r [DriveLetter:] command line, replacement [DriveLetter:] with the drive you want to analyze. If the command did not fix the problem, this may indicate that you need to replace your failed disk.

8. Check for memory issues

If your RAM isn’t working properly, your computer might restart on its own. Fortunately, you can run the Windows Memory Diagnostic Tool to identify issues.

To do this, open the Windows Memory Diagnostic Tool and click Reboot now and check for issues (recommended). Windows will then scan your RAM to see if it contains any errors.

9. Disable Automatic Restart

If you haven’t identified any issues with your system, you can try disabling the Windows 11 auto-restart feature.

  1. Launch Settings.
  2. Go to System > About.
  3. Of Related linksselect Advanced System Settings.
  4. In the System Properties window, open it Advanced tab and click Settings underneath Startup and recovery.
  5. Below System failureuncheck Restart automatically.
  6. Click on OKAY to save your new system settings.

This shouldn’t be a long-term fix because you’ve now prevented your computer from restarting in the event of a system crash, which could lead to more serious issues.

10. Restore Windows to a Previous Version

If you suspect that a recent system change is causing Windows 11 to restart randomly, you can revert your computer to its previous state to fix the problem. As long as you have created a restore point for your system, you should be able to use it.

Prevent Windows 11 from restarting on its own

As we have discussed, there are several reasons why Windows 11 may restart on its own. Sometimes there’s nothing wrong with your system, but it’s the hardware that’s giving you trouble. Although it might be difficult to pinpoint the cause, with a little patience you should fix it by following the solutions above.


If you recently updated to Windows 11, there are some things you need to do to make it work properly.
