So, let us understand what an unexpected kernel mode trap BSOD is and how to fix it.

What Is Meant by An “Unexpected Kernel Mode Trap Error”?

This is a Blue Screen of Death Error (BSOD) that happens when hardware dies or a driver is incompatible with the operating system.

If you didn’t have any of these issues with previous versions of Windows on the same PC, the issue is most likely due to driver incompatibility.

The unexpected kernel mode trap Windows 10 error, which is frequently connected to your system drivers or system memory, is commonly followed by the 0x0000007F stop code.

The unexpected kernel mode trap error is annoying, but it is not a difficult problem to resolve. When an error is identified, Windows shuts down the computer as a precautionary measure.

What Are the Causes of Unexpected Kernel Mode Trap Errors in Windows?

This issue might be caused by several factors. The most common reason is hardware failure, which is frequently caused by defective or mismatched memory.

This faulty RAM module causes read/write issues at unpredictable intervals. If this is the case, you must run a system diagnostic and replace the faulty RAM module.

A corrupted or out-of-date driver might be the next root of the problem. One or more device drivers may be misconfigured, corrupted, or simply out of date.

This may occur after updating Windows or downgrading from new system hardware to an older one, particularly if you are using an older version of Windows.

This issue might potentially be caused by corrupted software that is currently installed on your computer.

The problem in kernel mode is usually caused by one of two things: either the CPU generated a condition that the kernel isn’t permitted to record, or the situation is an unrecoverable error.

How to Fix an Unexpected Kernel Mode Trap or Error Code

You’ll have your computer up and running in no time if you follow the steps below.

This issue can be caused by a variety of drivers; however, some users recommend that uninstalling your Bluetooth, Wireless, and Intel RST (Intel Rapid Storage Technology) drivers will help.

It should be noted that this issue might be caused by any driver; it does not have to be related to Bluetooth or Wireless drivers, but they are commonly the offenders.

Finding drivers on your own may take a long time. As a result, we propose that you use a tool that will do this process automatically for you.

Using an automated driver updater saves you the time and effort of manually searching for drivers and ensures that your system is always up to date with the most recent drivers.

A professional tool will aid you in automatically upgrading drivers and preventing PC damage caused by incorrect driver version installation.

7. Execute the Windows 10 Memory Diagnostic Tool

Windows 10 has a Memory Diagnostic tool. It scans your RAM for errors and then generates a system log for more insight. While you’re attempting to repair a probable RAM issue, save any important files and restart your computer as soon as possible.

In the Start Menu search bar, type “Windows Memory” and choose the Best Match option. Choose to Run as an Administrator.

You now have two options: running the software right away or scheduling it to run after your next reboot. 

Following a reboot, the Windows Memory Diagnostic tool is launched.

Windows 10 will restart again once the operation is completed.

Press Windows Key + X to return to Windows 10 and choose Event Viewer from the menu. Go to Event Viewer (Local) > Windows Logs > System in the Event Viewer.

In the right-hand column, click Find and type MemoryDiagnostic into the box. Then, click the Find button.

9. Run MemTest86+

If the Windows Memory Diagnostic tool does not discover any faults but you want to validate them, you can use the open-source application MemTest86+. MemTest86+ is a self-contained memory testing application.

To test your system RAM, MemTest86+ is run from a USB flash drive (or a bootable disc). From the MemTest86+ website, obtain the most recent version of the pre-compiled Bootable ISO.

The ISO file for MemTest86+ must now be burnt to a USB flash drive. The Refus tool may be used to create a bootable USB flash drive from an ISO image.

Allow your computer to boot from the bootable USB device after it has been prepared. A memory test will begin immediately if you follow the onscreen instructions.

A MemTest86+ RAM check takes some time to complete; depending on how much RAM you have installed, an examination to identify it might take hours.

10. Disable the Memory Cache in the BIOS

If your device requires a BIOS update, try updating it via the manufacturer’s website. It should be noted that BIOS upgrades should be performed with extreme caution. If the BIOS update fails, your motherboard will be rendered worthless.

Disable memory settings such as caching and shadowing in the BIOS. In rare circumstances, disabling memory caching may aid in the resolution of the issue.

To accomplish this, restart your computer and enter the BIOS using the F2 or Del keys. From the Advanced Menu, choose Cache Memory.

Check to verify whether it is set to DISABLE. Use the F10 key to save and quit. Make sure you choose “Yes“.

11. Disable Overclocking in BIOS

Overclocking of the computer processor also causes the UNEXPECTED KERNEL MODE TRAP problem in the Windows computer.

If you have an overclocked CPU, that may be causing the problem. So it is time to return the CPU to its default clock speed by deactivating overclocking.

You can follow the quick instructions below to disable it.

Step 1: During the computer booting process, hit the F2 or Del key to enter BIOS according to your computer model.

Step 2: Go to the settings page for overclocking configuration. It may be termed Overdrive or AI Tweaker.

Take note of the CPU configuration. Turn off the Speed Step option here.

Alternatively, you may go to the Exit page and select Load Setup Defaults. Overclocking is often deactivated in the configuration defaults.

This procedure may be different according to the various BIOS settings used in the different computer models. 

12. Run SFC and CHKDSK

Another option is to use the built-in utility Windows System File Checker (SFC). This is a command-line program that looks for and performs possible corrections in system files if any mistakes are found.

So, this system program in Windows 10 can scan your drive and remove issues related to the 0x0000007F stop code. 

Before performing the SFC command, it is necessary to double-check its functionality. To do this, the Deployment Image Servicing and Management tool ( DISM), is employed.

DISM, like SFC, is an integrated Windows utility tool with a wide variety of functions. In this instance, the DISM Restorehealth command ensures that our next repair is successful.

Working your way through the steps listed below.

Type Command Prompt (Admin) into the Start menu search box, then right-click and choose Run as administrator.

Enter the command:

DISM /online /cleanup-image /restorehealth 

Allow for the completion of the command. Depending on the state of your system, the procedure might take up to 20 minutes. Wait for the process to finish even though it appears to be stopped at times.

When the procedure is finished, type the following command at the command prompt to perform SFC and hit Enter.

sfc /scannow


CHKDSK is another Windows system utility that analyses your file structure. Unlike SFC, CHKDSK examines your whole hard drive for errors, whereas SFC just checks your Windows system files.

To restore your system, use the Command Prompt to run the CHKDSK scan, much like SFC.

Enter “command prompt” in the Start menu search box, then select the best result and pick “Run as administrator.” Or hold down Windows Key + X and select Command Prompt (Admin) from the menu.

Then, type chkdsk /r and press Enter.

The application will scan your system for problems and fix any issues it discovers.

After conducting these SFC scans and CHDSK operations, reboot your system and check for errors.

13. Uninstall Your Graphics Card Driver

This issue, according to some users, might be caused by the graphics card driver. Several users have reported having this problem with the current Nvidia drivers, and they believe that returning to older versions of the driver is the fix.

To achieve this, just uninstall the Nvidia driver from Device Manager. Windows will install the default driver when you restart your computer after deleting the driver.

Check to see whether the issue persists with the default driver as well. If the problem persists, remove the graphic card entirely and investigate the cause of the error.
