Blue Screen of Death errors are one of the most serious errors on Windows 10, and since these errors will crash and restart your PC, they can be a major problem. BSoD errors can be quite serious, therefore today we’re going to show you how to fix KERNEL MODE EXCEPTION NOT HANDLED error.

  5. Run DISM
  6. Check the hard drive
  7. Uninstall the problematic applications
  8. Uninstall your antivirus software
  9. Update BIOS
  10. Reset Windows 10
  11. Check your hardware


Solution 1 – Update Windows 10

Certain hardware or software might not be fully compatible with Windows 10, and that can cause errors such as KERNEL_MODE_EXCEPTION_NOT_HANDLED to appear. In order to prevent these types of errors from appearing it’s crucial that you update Windows 10 regularly. By using Windows Update you’ll download the latest bug fixes that are designed to resolve many hardware and software issues on Windows 10 and thus fix the BSoD error. In addition to bug fixes, latest Windows 10 patches offer many security improvements and new features, so if you wish to keep Windows 10 safe and stable, be sure that you download them.

Solution 2 – Update your drivers

Many BSoD errors are caused by outdated or incompatible drivers. If certain driver isn’t compatible with Windows 10 that can often cause KERNEL_MODE_EXCEPTION_NOT_HANDLED error to appear, and the only solution is to update the problematic driver. Updating drivers is fairly simple, and in order to do it, you can use the Device Manager by following the steps:

  1. Press Windows Key + X to open Power User Menu. Select Device Manager from the list.
  2. Once Device Manager opens, locate the device you wish to update, right click it and choose Update Driver Software.
  3. Select Search automatically for updated driver software. Windows 10 will now download and install the appropriate driver for your device.
  4. Repeat these steps for all devices that you wish to update.

Some users claim that using Device Manager to update your drivers isn’t the most effective solution since it might not always download the latest drivers. To ensure that you have the latest drivers, it’s best that you visit your hardware manufacturer’s website and download the latest drivers for your device.

Update drivers automatically

Searching for drivers on your own can be time-consuming. So, we advise you to use a tool that will do this for you automatically. Using an automatic driver updater will certainly save you from the hassle of searching for drivers manually, and it will always keep your system up to date with the latest drivers.

These tools will help you update drivers automatically and prevent PC damage caused by installing the wrong driver versions. 

After several tests, our team concluded that this is the best-automatized solution.

Various errors are the result of a malfunctioning driver. When this is the case, you may need to update or reinstall completely this specific component. As the process is not straight-forward to complete, we recommend using an automated tool for the job. Here's how to do it:

  1. Download and install DriverFix.
  2. Launch the app.
  3. Wait for the software to detect all your faulty drivers.
  4. You will now be presented with a list of all the drivers that have issues, and you just need to select the ones you’d liked fixed.
  5. Wait for DriverFix to download and install the newest drivers.
  6. Restart your PC for the changes to take effect.

Solution 3 – Run the BSOD Troubleshooter 

If the built-in troubleshooter failed to resolve the problem, let’s try the SFC scan. This command-line tool scans your system and searches for potential problems. The SFC scan will automatically resolve any issue, if the solution is possible.

Here’s how to run the SFC scan in Windows 10:

  1. Open the Settings app and go to Update & Security section.
  2. Select Troubleshoot from the menu on the left.
  3. Select BSOD from the right pane and click Run the troubleshooter.
  4. Follow the instructions on the screen to complete the troubleshooter.

Solution 4 – Run the SFC scan

The next troubleshooter we’re going to try is the SFC scan. This is a command-line tool that goes through your system searching for potential issues. Of course, if resolving these issues is possible, the SFC scan will do it automatically.

Here’s how to run the SFC scan in Windows 10:

  1. Right-click on the Start Menu button, and open Command Prompt (Admin).
  2. Enter the following line and press Enter: sfc/scannow
  3. Wait until the process is done (it may take a while).
  4. If the solution is found, it will automatically be applied.
  5. Now, close the Command Prompt and restart your computer.

Solution 5 – Run DISM

And the final troubleshooting tool we’re going to try here is DISM. Deployment Image Servicing and Management is a command-line utility that reloads the system image. Reloading the system image can eliminate various problems, including (hopefully) the BSOD errors.

Expert Tip: Some PC issues are hard to tackle, especially when it comes to corrupted repositories or missing Windows files. If you are having troubles fixing an error, your system may be partially broken. We recommend installing Restoro, a tool that will scan your machine and identify what the fault is.

  • Standard way
  1. Right-click Start and open Command Prompt (Admin).
  2. Paste the following command and press Enter:
    • DISM /Online /Cleanup-Image /RestoreHealth
  3. Wait until the scan is finished.
  4. Restart your computer and try updating again.
  • With the Windows installation media
  1. Insert your Windows installation media.
  2. Right-click the Start menu and, from the menu, choose the Command Prompt (Admin).
  3. In the command line, type the following commands and press Enter after each:
    • dism /online /cleanup-image /scanhealth
    • dism /online /cleanup-image /restorehealth
  4. Now, type the following command and press Enter:
    • DISM /Online /Cleanup-Image /RestoreHealth /source:WIM:X:SourcesInstall.wim:1 /LimitAccess
  5. Make sure to change an X value with the letter of the mounted drive with Windows 10 installation.
  6. After the procedure is finished, restart your computer.

Solution 6 – Check the hard drive

Sometimes BSoD errors like KERNEL MODE EXCEPTION NOT HANDLED can appear due to corrupted files on your hard drive, and in order to fix this problem you’ll need to check your hard drive by using chkdsk command. To do that, follow these steps:

  1. Enter the Advanced Startup (Restart your computer while holding the Shift key).
  2. Choose Troubleshoot > Advanced Options.
  3. Select Command Prompt from the list of options.
  4. When Command Prompt appears, enter the following lines and press Enter after each line in order to run it:
    • bootrec.exe /rebuildbcd
    • bootrec.exe /fixmbr
    • bootrec.exe /fixboot
  5. Some users are also suggesting that you need to run additional chkdsk commands as well. To perform these commands, you need to know drive letters for all your hard drive partitions. In Command Prompt you should enter the following (but remember to use the letters that match your hard drive partitions on your PC):
    • chkdsk /r c:
    • chkdsk /r d:

    This is just our example, so keep in mind that you have to perform chkdsk command for every hard drive partition that you have.

  6. Restart your computer and check if the issue is resolved.

Solution 7 – Uninstall the problematic applications

Sometimes certain applications can cause these types of errors to appear, and in order to fix KERNEL_MODE_EXCEPTION_NOT_HANDLED error, you’ll have to find and remove the problematic application. It’s worth mentioning that this problem can occur if you install or update a certain software, therefore, if you updated or installed any new application recently, be sure that you remove it. In addition to applications, drivers can also be the common cause for these types of errors, and if you updated a certain driver recently, that can also cause Blue Screen of Death error to appear. If that’s the cause, we strongly advise you to uninstall any recently updated driver by following these steps:

  1. Open Device Manager by pressing Windows Key + X and choosing Device Manager from the list.
  2. When Device Manager opens, locate the problematic driver, right click it and choose Uninstall.
  3. If available, check Delete driver software for this device and click OK.

After you remove the problematic driver, restart your PC. Windows 10 will now install the default driver, and if the default driver works well you can continue using it. If you want, you can download a new driver, but be careful not to install the problematic driver again.

Solution 8 – Uninstall your antivirus software

Having antivirus software installed on your PC is crucial for your safety, but unfortunately, antivirus software can sometimes cause KERNEL_MODE_EXCEPTION_NOT_HANDLED BSoD error to appear. Therefore, if you’re getting this error it’s recommended that you uninstall any third-party antivirus programs that you have installed.

It’s worth mentioning that uninstalling antivirus software isn’t always enough, since many of these tools leave certain files and registry entries behind once you uninstall them. To completely remove a certain antivirus program, you should use a dedicated removal tool. Almost all major antivirus companies offer these tools for download, so be sure to download one for your antivirus software.

Solution 9 – Update BIOS

Updating BIOS brings new features to your motherboard, and in addition to new features, it can also fix some BSoD errors such as KERNEL_MODE_EXCEPTION_NOT_HANDLED. In order to update BIOS, it’s important that you download the latest version from your motherboard manufacturer’s website. We have to notice that updating BIOS is an advanced procedure, therefore be extra cautious while performing it, unless you want to cause permanent damage to your PC. For detailed instructions on how to update your BIOS, be sure to check your motherboard manual.

Solution 10 – Reset Windows 10

If the KERNEL_MODE_EXCEPTION_NOT_HANDLED error is caused by a software issue, you should be able to fix it by performing Windows 10 reset. This procedure is similar to clean install, therefore be sure to back up all important files and folders from your C partition. We also have to mention that you might need a Windows 10 installation media in order to complete this process, and you can easily create a bootable USB flash drive by using Media Creation Tool. To perform Windows 10 reset, do the following:

  1. Restart your computer few times while it boots to start Automatic Repair process.
  2. Select Troubleshoot > Reset this PC > Remove everything. If you get asked to insert Windows 10 installation media be sure to do so.
  3. Select Only the drive where Windows is installed > Just remove my files.
  4. Click the Reset button and wait for the reset process to finish.

If the problem persists even after Windows 10 reset, it’s most likely that the error is caused by a faulty hardware.

Solution 11 – Check your hardware

These types of errors can often be caused by faulty hardware, so be sure to check if your RAM is working properly. To check your RAM we advise that you use MemTest86+ in order to perform thorough scan. If your RAM is working properly, be sure that you check all other major hardware components.

KERNEL_MODE_EXCEPTION_NOT_HANDLED can be a major problem on Windows 10, but we hope that you managed to fix this error by using one of our solutions.
