Common BSOD errors we have introduced include nvlddmkm.sys blue screen error, igdkmd64.sys blue screen error and SYSTEM SERVICE EXCEPTION Blue screen error etc. Generally, the BSOD problem appears along with an error code, which helps to determine what kind of problem the system is having with the hardware.  In Windows 10, a frequently-appeared error named Kmode Exception Not Handled has affected many users. Also, there were such errors in Windows 8. Here, we introduce some effective ways to fix “Kmode Exception Not Handled” error in Windows 10.

What is Kmode Exception Not Handled?

Kmode Exception Not Handled is a system crash. The crash happens when a Kernel Mode Program is causing an exception, which the error handler is not able to identify. Generally, there will be an error code 0x0000001E and sometimes the system falls into loop reboot.

How to Fix Kmode Exception Not Handled Error?

To fix Kmode Exception Not Handled error effectively, you can try the following ways:

Turn off fast startup

Run Windows Memory Diagnostics

Update device drivers

Method one: Turn off fast startup

Windows fast startup is a feature that users can set for their own startup preference. It’s available for Windows 8 and Windows 10 systems, which works similarly to the hybrid sleep mode of the previous Windows versions. By saving the operating system state to a hibernation file, fast startup can make your computer boot up even quicker.

However, fast startup can also cause system crash when there is trouble reloading the kernel, drivers, and system state normally. Sometimes BSOD error occurs, like the Kmode Exception Not Handled error. Then you may need to turn off fast startup for normal boot.

1. Win + R and input “Control panel”, then hit Enter;


2. Search for Power Options;


3. Click Choose what the power buttons do;


4. Then Change settings that are currently unavailable;


5. Untick the choice Turn on fast startup, then Click Save changes and exit;


After the settings, you can restart your computer and check if the Kmode Exception Not Handled error has been repaired.

Windows Memory Diagnostic is a system memory test. It can help check the computer’s RAM for problems. During the test process, there will be a status bar showing you if any problems have been detected. Also, Windows Memory Diagnostics can help check the kmode exception not handled error.

1. Open Windows memory diagnostics through searching from the search box of Windows 10;

2. Click restart now and check for problems (recommend).


Repair the problems that have been detected and restart Windows.

Method three: Update device drivers

If the kmode exception not handled error is caused by the outdated device driver, you can choose to update the driver manually in Device Manager or automatically update it with a driver updater.

Update driver in Device Manager

1. Win + X and choose Device Manager;


2. Locate at “other devices” and right click to update the driver;


3. Search automatically for updated driver software and wait for the result.
