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.
