The UNEXPECTED KERNEL MODE TRAP error is one of many annoying blue screen occurrences in Windows. Furthermore, as the name implies, it is occurring unexpectedly.
As with other blue screen problems, this is never fun. It will crash your computer and take your work with it.
The most common cause is hardware failure caused by faulty or mismatched memory. There may be occasions when your computer has faulty software that creates an error.
The error code appeared before Windows 8. Kernel mode trap error in Windows 11 and Windows 10 is displayed as UNEXPECTED_KERNEL_MODE_TRAP.
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A corrupted or out-of-date driver might be the next root of the problem. One or more device drivers may be misconfigured, corrupted, or simply out of date.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 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 also.
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.
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.
