A Technical Guide to fix KMODE Exception not handled errors in Windows 10

The KMODE error is a type of STOP error. It is also known as Blue Screen of Death – BSOD. It forces the computer to restart. The error can happen again while restarting.

Why does the problem occur?

The error occurs when the applications try to overwrite each other’s memory. The blue screen means a complete system crash has occurred. It can also be due to

  1. Faulty hardware devices
  2. Incompatibility of the drivers
  3. Recently installed programs
  4. Corrupt or conflicting system services

What exactly happens?

Some software has been corrupted. The Windows error handler is not knowing how to fix this. It is not able to find the problem causing software. In most cases the culprit are the drivers.

Here is a complete guide to fix these types of errors

Disable fast startup

Fast startup is a feature first introduced in Windows 8. With fast startup enabled the PC is entering a mixed state of shutdown and hibernation. It means some programs are OFF and some are ON.

The kernel, drivers and system states are ON in this state.

How to disable fast startup?

Control Panel à System Security à Power options à Choose what power buttons do à Change settings that are currently available à Uncheck Turn on fast start – up à Save changes

Update the drivers

Old corrupt drivers trigger the problem of BSOD. The only solution to fix this problem is to update the drivers.

How to update the drivers?

  1. Boot the system in safe mode – How?
    1. This is done by interrupting the normal booting process 3 times
    2. Turn ON the PC and press the power button before it finishes booting.
    3. In order to make this work, one has to hold the power button up to 4 seconds.
    4. When the system boots the 4th time, it automatically enters safe mode
  2. Notice the automatically repairing updates being displayed
  3. Chose Advanced options à Troubleshoot
  4. On the troubleshoot screen, again select Advanced options à Startup Settings à press number 4 à Restart
  5. When the system restarts, hit on number 4 again. This forces the system to boot in safe mode
  6. After the system has booted in safe mode, follow these steps
    1. Press Windows key + X simultaneously
    2. Choose Device manager à Other devices
    3. Right click on the unknown device (it says unknown as the system software is unable to find what it is as it is the problem causing driver)
    4. Click on Update driver software à Search automatically for updated driver software
    5. Wait for the drivers to update.

This is a lengthier method to fix the KMode Exception Not Handled errors. However, it is the most effective method.

Allow the Windows to fix itself

This might sound counterintuitive. But Windows has an option called SFC scan to repair the problem. It inspects every windows program file. The corrupt file is found and fixed.

What is SFC scan?

SFC is System File Checker. It is commonly called the “scan now” option. It scans the protected system files and replaces the corrupt file with a cached copy. (Cache copy is temporary storage for easy access and fast working of the Windows)

How to run SFC scan?

  1. Open command prompt – How?
    1. Press windows key + R simultaneously
    2. Type cmd in the dialogue box that opens
    3. A black screen opens. This is called the command prompt
  2. Type sfc/scannow and hit enter
  3. The process takes a while to finish
  4. Restart system once the process is completed.

If the error doesn’t show up again, it means the corrupt file is fixed. Else, try out alternate options.

Run a memory test

It is used to check the memory failures on the PC. The BSOD problem occurs mainly because applications compete for the same memory space. This can be caused by corrupt applications or lack of memory space or other memory related issues. Either way, BSOD problem occurring due to memory problems can be fixed by running a memory test.

How to run a memory test?

Control Panel à Administrative tools à Windows Memory Diagnostic à Restart now and check for problems

If the problem is not fixed, the message says RAM needs replacement. In that case, go for an alternate option.

Other options

  1. The KMode Exception Not Handled errors can even be due to obsolete version of BIOS. It means that the BIOS has to be updated. Not down the BIOS number and manufacture details. Search for the BIOS replacement techniques online. Adopt an easy and simple method.
  2. Uninstall suspicious software
    1. Control panel à Programs à Uninstall a program
    2. A list of programs is displayed
    3. Uninstall the recently installed program or the program which the user feels is causing the problem
  3. Disable the corrupted driver
    1. Start à Type verifier in the search
    2. Select create standard settings and say next
    3. Select Automatically select all drivers installed on the computer and say finish
    4. A list of unsigned drivers is displayed. Uninstall all of them.
  4. Uninstall anti – virus
    1. Sometimes anti – virus hinder normal functioning of window. This obstructs Windows to fix its errors
    2. Uninstall anti – virus, restart the system.
    3. Allow the windows to fix the errors
    4. Re – install the anti-virus.

There are other methods to fix the BSOD errors. However, these are the most efficient ones.
