Although many users have switched to Windows 10, it doesn’t mean that these users aren’t experiencing issues on Windows 10. One of the issues that users are experiencing on Windows 10 is UNEXPECTED_KERNEL_MODE_TRAP error so let’s see if we can fix this issue.

UNEXPECTED_KERNEL_MODE_TRAP is a Blue Screen of Death error that is caused by hardware failure or by incompatible driver. If you didn’t have any of these issues on previous versions of Windows then the issue isn’t caused by hardware, it’s probably incompatible driver.

In some cases, this error can be caused if your component connectors are covered in dust, so you’ll need to remove them and clean them properly before connecting them again.

If your computer is under warranty or you don’t know how to do it, it’s best to hire an expert to do it for you. But if this issue started appearing after you’ve switched to Windows 10, it’s most likely a driver issue, so let’s see how to fix it.

UNEXPECTED_KERNEL_MODE_TRAP can be an annoying error, and users reported the following issues as well:

We have to warn you that this issue can be caused by another driver, it doesn’t have to be related to Bluetooth or Wireless drivers, but they are often the main causes for this issue.

  2. In Advanced Startup choose Troubleshoot > Advanced Options > Startup Settings.
  3. You should see an option to enter Safe Mode.
  4. When you enter Safe Mode, go to Device Manager.

Solution 2 – Disable uninstall your security software

According to users, sometimes third-party antivirus software can cause this problem to appear. Your antivirus or firewall can interfere with your Windows installation, and in order to fix the problem, you need to disable your antivirus.

If disabling the antivirus or firewall doesn’t fix the issue, you might have to uninstall it. To completely remove your antivirus, it’s recommended to download a dedicated removal tool for it from the developer’s website. After removing the antivirus, check if the problem is resolved.

If removing the antivirus fixes the issue, you can reinstall your antivirus or switch to a different antivirus solution. You can also use Windows Defender instead of a third-party antivirus. Several users reported that Avast was the problem on their PC, but keep in mind that almost any antivirus software can cause this problem to appear.


Solution 3 – Install the latest updates

If you’re getting UNEXPECTED_KERNEL_MODE_TRAP error on your PC, you might be able to fix it by installing the latest updates. To do that, you need to do the following:

  1. Open the Settings app. You can do that quickly by using Windows Key + I shortcut.
  2. When Settings app opens, navigate to the Update & security section.

Solution 5 – Remove your graphics card driver

According to users, your graphics card driver can be the cause for UNEXPECTED_KERNEL_MODE_TRAP error. Several users reported this issue with latest Nvidia drivers, and according to them, the solution is to revert to the older drivers.

To do that, simply remove Nvidia driver from Device Manager. If you want to remove all files associated with your graphics card, we wrote a small tutorial on how to use Display Driver Uninstaller, so be sure to check it out.

After removing the driver, Windows will install the default driver once you restart your PC. Now check if the issue reappears with the default driver. Keep in mind that Windows 10 can sometimes update your driver automatically in the background causing the error to reappear. However, you can easily prevent Windows from automatically updating certain drivers.


Solution 6 – Check if your cables are properly connected

Unexpected Kernel Mode Trap BSOD

In few cases users reported that UNEXPECTED_KERNEL_MODE_TRAP error was caused by their hardware. According to them, their connectors weren’t firmly in place, but after properly connecting loose cables, the issue was resolved.

In addition to cables, be sure to check if your RAM is firmly locked in its slot. Few users reported that RAM can be the problem so double check it to see if it’s properly seated.


Solution 7 – Check your RAM

Unexpected Kernel Mode Trap overclock

Faulty RAM is a common cause for Blue Screen errors such as UNEXPECTED_KERNEL_MODE_TRAP. However, you can test your RAM to determine if it’s faulty. The simplest way to do that is to remove all but one modules from your PC and check if the issue reappears. Now you need to repeat this until you test all modules.

However, if you want to perform a detailed scan, you’ll need to use a tool such as Memtest86+ to test your RAM. Keep in mind that you need to test each module individually. To perform a detailed scan, you need to keep the test running for hour or so for each module.


Solution 8 – Reset Windows 10

If the problem still appears, you might have to reset your PC. This process will delete all files from your system drive, so be sure to back them up. In addition, you might need a Windows 10 installation media to complete this process, so create it with Media Creation Tool.

To perform the reset, you need to do the following:

  1. Start Advanced Startup. We briefly mentioned how to do that in Solution 1, so check it for detailed instructions.
  2. Choose Troubleshoot > Reset this PC > Remove everything.
  3. You might be asked to insert your installation media to proceed to the next step, so be sure to have it ready.
  4. Choose your version of Windows and select Only the drive where Windows is installed > Just remove my files.
  5. Now you’ll see the list of changes that reset will perform. Once you’re ready to start, click on Reset.
  6. Follow the instructions on the screen to complete the reset.

After finishing the reset, you’ll have a fresh installation of Windows 10 and your problem should be resolved.


If you’re trying to upgrade to Windows 10, you can delete these drivers on your current operating system, and then upgrade to Windows 10 in order to avoid these issues.
