What is the KMODE_EXCEPTION_NOT_HANDLED error in Windows?

When you get a “blue screen” error on your computer, it can be an unpredictable and frustrating experience. It often occurs when something is wrong with one of the system files in Windows or another program that runs simultaneously that causes this issue. 

Most blue screen errors are associated with system-related issues that send a STOP code to Windows, leading to an immediate system crash. This happens without warning, meaning work can be lost, and files can occasionally get corrupted. Make sure to save frequently!

But don’t worry! There’s always a solution to any blue screen error. You will want to check out these things before giving up hope: 

  • Make sure all system updates are installed;
  • Repair any damaged configurable settings using built-in tools like the System File Checker and DISM;
  • Update your drivers;
  • Check your boot settings.

Windows users have reported many instances of a driver-related blue screen error, one of which is the “KMODE_EXCEPTION_NOT_HANDLED” error code, also known as stop code. Luckily, there are several potential solutions you can apply to get rid of it and return to using your computer as usual.

What causes the KMODE_EXCEPTION_NOT_HANDLED error?

The error message “KMODE EXCEPTION NOT HANDLED” does not appear to be particularly useful at first look. Even users with plenty of Windows experience may have trouble deciding on the next step when this stop code appears as Windows starts up. So, what does it mean?

When software or apps overwrite one other’s memory, the KMODE_EXCEPTION_NOT_HANDLED error occurs. It causes the software to crash and make your system crash with a Blue Screen of Death.


It’s critical to address this Windows issue as soon as possible because it will almost certainly continue to occur until you resolve it! We’ve developed a list of seven viable options to assist you in quickly restoring your PC.

Method 1. Disable the Fast Startup feature

Fast startup is enabled by default on practically all Windows computers. The function helps your computer boot quicker or recover from hibernation more quickly, but it can also cause Windows to fail to launch correctly or revert to earlier faults.

  1. Click on the Windows icon in your taskbar and search for the Control Panel. Launch the application from the search results.

  2. Click on Power Options. If you can’t see this, make sure to switch the view mode to either Large icons or Small icons.
    control panel > power options
  3. Click on the Choose what the power button does link in the left-side pane. You’ll be redirected to a new page.

  5. Make sure to uncheck the Turn on fast startup (recommended) option. Click the Save changes button to apply the changes before restarting your computer.
    turn on fast startup

Method 2. Clean boot your computer

Start in “clean boot” mode to guarantee that your computer operates without third-party services. Before booting, this will remove any apps and third-party conflicts. Check whether Windows experiences the KMODE_EXCEPTION_NOT_HANDLED BSOD when in this boot mode.

  1. Press the Windows + R keys on your keyboard to bring up the Run utility in a new window.
  2. Type in “msconfig” without the quotation marks and press the Enter key on your keyboard. This will launch the System Configuration window.

  3. Switch over to the Services tab. Make sure that you check the Hide all Microsoft services box. This is going to ensure that you only see third-party services.

  4. After hiding all system services, click the Disable all button to disable every third-party service on your device.

  5. Click the Apply button and restart your computer. When you boot next, your computer will only initiate essential Microsoft services.
  6. Restart your computer. You’ll be in a clean boot state with only official Microsoft services.

If you observe that the KMODE_EXCEPTION_NOT_HANDLED blue screen problem disappears after a clean boot, a service likely is to blame. You must locate it and either replace the linked driver or app or turn off the service entirely.

Method 3. Update your network drivers

Windows Update has a feature that allows you to update outdated drivers automatically. This can help you quickly find and get some of your drivers up-to-date without individually checking for new versions.

Use the steps below to update a network driver that may be outdated manually. Keep in mind that only legitimate sites should be used to download drivers! Some fraudulent websites may try to trick you into downloading malware-infected driver files.

  1. Press the Windows + X keys on your keyboard and choose Device Manager from the context menu to access the needed utility.

  3. Choose how you want to update your driver. You may either let Windows find a driver for you automatically or manually seek a new driver file on your machine.

Method 4. Run the Windows Memory Diagnostics

The Windows Memory Diagnostic tool is a built-in Windows utility for locating and resolving system memory issues. It will test your RAM and notify you if any problems interfere with its operation.

  1. Press the Windows + R keys on your keyboard to bring up the Run utility. Here, type in “mdsched.exe” and press the OK button.
  2. Choose “Restart now and check for problems (recommended)” to instantly begin a memory scan. Make sure to save any files and close all open applications before clicking on this option.
    restart now and check for problems
  3. Alternatively, choose “Check for problems the next time I start my computer” and restart the device at a more convenient time.
  4. The Windows Memory Diagnostics Tool interface will then show up and automatically start testing your PC’s memory problems. The process may take a few minutes, so you should be patient and let it run till completion and display the test results.

If the Windows diagnostic tool finds and displays no faults, your PC’s memory is most likely in good condition and functioning as intended. If this is the case, use a different approach from this article to try to fix the KMODE_EXCEPTION_NOT_HANDLED BSOD error.

Method 5. Temporarily disable your antivirus app

Antivirus apps are a necessity on your computer if you want to stay safe while online. However, many of them cause errors, and some may even mess up your drivers. If this happens, you need to disable your antivirus temporarily.

  1. Right-click on space in your taskbar and choose Task Manager from the context menu.
  2. Switch to the Startup tab using the header menu located at the top of the window. Find your antivirus application from the list and select it by clicking on it once.
  3. Click on the Disable button now visible in the bottom-right of the window. This will disable the application from launching when you start your device.

  4. Check whether you can use your computer after making this update by restarting it. Remember to restart your antivirus program subsequently, or purchase a new one if your present one was the source of the problem!

Method 6. Run the System File Checker

Corrupted system files can cause various issues on your computer, one of which happens to be blue screen errors and unnatural resource consumption. If some essential Windows files have been tampered with or damaged somehow, they need to be repaired.

Use the built-in System File Checker (SFC scan) to detect and replace any damaged system files you may have.

  1. Open the search bar in your taskbar by clicking on the magnifying glass icon. You can also bring it up with the Windows + S keyboard shortcut.
  2. Type Command Prompt in the search box. When you see it in the results, right-click on it and choose Run as Administrator. If you’re using a local account that doesn’t have administrator permissions, click here first.
    run command prompt as admin
  3. When prompted by the User Account Control (UAC), click Yes to allow the app to launch with administrative permissions.
  4. Type in the following command and press Enter to execute it: sfc /scannow
    sfc/ scannow
  5. Wait for the System File Checker to finish scanning your computer. In the case of a discrepancy, the utility will restore system files and fix all errors.

Method 7. Update your BIOS

The computer might not be working correctly because its BIOS has become outdated. You can fix this by updating your system’s software, which could also improve performance and stability issues related to older versions of the BIOS you’re using!

  1. Press the Windows + R keys on your keyboard. This is going to bring up the Run utility.
  2. Type in “cmd” without the quotation marks and press the Enter key on your keyboard. This will launch the Command Prompt application.
    cmd > command prompt
  3. Next, type the following commands one by one. Hit the Enter key after each command line to execute the command:
    • systeminfo | findstr /I /c:bios
    • wmic bios get manufacturer, smbiosbiosversion
      update BIOS
  4. These commands will help you identify the BIOS version. Use it to find the latest files required to update your BIOS, unless you’re already on the latest version.
