How to Fix Kmode Exception Not Handled Error in Windows: Steps to Follow

The Blue Screen of Death (BSOD) is a common error for many Windows users and can cause system crashes in a number of different ways. Common problems of BSOD (Blue Screen of Death) or blue screen include errors like nvlddmkm.sys, igdkmd64.sys and SYSTEM_SERVICE_EXCEPTION. Generally, these problems appear with an error code that helps us determine what type of problem the system is having with the hardware. In Windows 10, the “Kmode Exception Not Handled” error appears frequently and affects a large number of users. These errors occurred before in Windows 8, but here we will introduce several effective ways to fix the “Kmode Exception Not Handled” error in Windows 10. Let’s get started.

Kmode Exception Not Handled Error: All You Need to Know

What does Kmode Exception Not Handled mean?

Kmode Exception Not Handled is a bug in the system. The failure occurs when a kernel program causes an exception that cannot be identified by the error handler. There will usually be an error code 0x0000001E and occasionally the system may enter a reboot loop. 

How to Fix Kmode Exception Not Handled Error?

To fix the Kmode Exception Not handled error effectively, you can try the following solutions:

  • Disable Quick Start
  • Run the Windows Memory Diagnostic
  • Update Device Drivers

Method 1: Disable Quick Launch

Windows Quick Start is a feature that users can use to create their own startup preference. It is available in Windows 8 and Windows 10, and works similar to the hibernate mode in previous versions of Windows. By saving your operating system to a file hibernation state, Quick Start can make your computer start up even faster.

On the other hand, fast startup can also cause system errors when it cannot run the kernel drivers. Sometimes the BSOD problem occurs, as well as the Kmode Exception Not Handled Error. You may need to disable fast startup for a normal system startup. 

1.  Win  +  R and type ” Control Panel ” and hit enter;


2. Search for ” Power Options “


3. Select “ Choose what the Energy buttons can do ”;


4. Change the options that are not currently available


5. Uncheck the ” Enable fast startup ” tick. Then save changes and exit.


Now you can restart your computer and check that the “Kmode Exception Not Handled” error has been fixed.

Method 2: Run the Windows Memory Diagnostic

The Windows Memory Diagnostic is a test of the system memory. It can help you to see the problems in the RAM of the computer. During the process, there will be a status bar, showing if a problem has been detected. Additionally, the Windows Memory Diagnostic can help you check the “kmode exception not handled” error.

1. Open the Windows memory diagnostic through the Windows 10 search box;

2. Click restart now and review the issues (recommended).


Repair any problems that have been detected and restart Windows.

Method 3. Update device drivers.

If the “kmode exception not handled” error is caused by outdated drivers, you can choose to update the drivers manually from Device Manager or update them automatically with a driver update program.

Update drivers through Device Manager

1.  Win  +  X  and click Device Manager;


2. Locate “other devices” and right click on update driver;


3. Automatically check for driver updates and wait for the search to finish.


Pay attention to the compatibility of the driver with your system.

Update the driver with a driver updater.

For many users it is miserable to have to update their device drivers themselves, so a driver updater is necessary to help them update their outdated drivers automatically. There are certain tools that can update more than 3,000,000 device drivers and fix common driver problems efficiently.

Once you have finished updating all your drivers, you can go ahead and restart your system and check if the “kmode exception not handled” error has been fixed.

So those were the different methods with which you can fix kmode exception not handled error on Windows. If none of these methods work for you, it’d be best for you to contact your system manufacturer for support.
