How To Fix "KMODE_EXCEPTION_NOT_HANDLED" Error On Windows 10?

Blue Screen of Death (also known as a blue screen or BSoD or a STOP error) is an error screen displayed on a Windows computer system after a fatal system error, also known as a system crash: when the operating system reaches a condition where it can no longer operate safely or Windows must stop completely. It usually appears when Windows encounters a critical error and it cannot recover. There is a number of blue screen types and it also depends on the version of Windows operating system.

Blue screens are generally caused by problems with your computer’s hardware or issues with its hardware driver software. At this point there is only one thing that you can do - to restart your computer, but if there is some programs with their data open, Windows won't be able to save it. But there is one thing that will be definitely saved: Windows automatically creates a file called “minidump” that contains information about the crash and saves it to your disk. You can view information about minidumps to help identify the cause of the blue screen. However, a minidump file does not contain as much information as a full crash dump file, but it contains enough information to perform basic debugging operations.

Run The SFC Scan

Sometimes this "KMODE_EXCEPTION_NOT_HANDLED" error can appear because of the corrupted system files and to fix this issue you need to run SFC scan. System File Checker is a utility in Windows that allows users to scan for corruptions in Windows system files and restore corrupted files. This guide describes how to run the System File Checker tool (SFC.exe) to scan your system files and to repair missing or corrupted system files. If a Windows Resource Protection (WRP) file is missing or is corrupted, Windows may not behave as expected. For example, some Windows functions may not work, or Windows may crash. The "sfc /scannow" option is one of the several specific switches available in the sfc command, the Command Prompt command used to run System File Checker. To run it you need to open Command Propmt first. To open it type "command prompt" in Search and then right-click on the "Command Prompt", select "Run as administrator" from the dropdown menu to run Command Prompt with administrator privileges. You must run an elevated Command Prompt in order to be able to perform SFC scan.

run sfc scan step 1

In opened Command Prompt window type "sfc /scannow" and press Enter on your keyboard to execute this command. System File Checker will start and it should take some time to complete the scan. It should take about 15 minutes. Wait for the scanning process to complete and then restart your computer to see if the "KMODE_EXCEPTION_NOT_HANDLED" error still persists.

Uninstall BitDefender And Other Software

If you are using BitDefender anti-virus software, then try to uninstall it and see if this "KMODE_EXCEPTION_NOT_HANDLED" error still persists. We are suggesting this only because there are numerous reports where users are stating that this particular software is causing this error. If that is really the case on your computer as well, then we recommend you to change your anti-virus software to another one, or to use Windows built-in Windows Defender. If uninstalling BitDefender does not help you can install it again. If you are using Cisco VPN client, McAfee antivirus software or ON/OFF Gigabyte then try uninstalling them well, since these three could also cause this "KMODE_EXCEPTION_NOT_HANDLED" error.
