By following the procedures outlined below, you will learn how to update drivers, run system diagnostics, and adjust system settings to restore your PC’s functionality, whether you’re using Windows 10 or Windows 11 on a desktop or laptop.
Step 1: Update or Reinstall Drivers
Driver issues are often at the root of the KMODE_EXCEPTION_NOT_HANDLED error. Start by updating your display and storage drivers, as these are frequently associated with system instability. To do this, right-click the Start button and select Device Manager. Locate Display Adapters, expand the section, right-click your graphics device, and choose Update Driver. Select Search automatically for drivers. Ensure to repeat this for any storage devices listed under Disk Drives. If an update does not resolve the error, you may want to uninstall the driver and reboot your system, allowing Windows to reinstall the driver automatically.
Step 2: Run System File Checker (SFC) and DISM Tools
Corrupted system files can lead to significant errors. To repair these files, you should utilize the System File Checker and the DISM tool. Open the Command Prompt as an administrator by searching for cmd in the Start menu, right-clicking it, and selecting Run as administrator. In the Command Prompt, type sfc /scannow and press Enter. Allow the scan to complete, which may take several minutes. Afterward, execute the command DISM /Online /Cleanup-Image /RestoreHealth to repair the Windows image. This process ensures that all files are intact and functioning correctly.
Step 3: Check for RAM Issues
Faulty RAM can directly lead to system crashes. Use the Windows Memory Diagnostic tool to detect issues with your memory. Type “Windows Memory Diagnostic” in the Start menu search and select the application. You can choose to restart your computer immediately and check for problems or schedule the check for the next boot. The tool will assess your RAM’s functionality and report any issues detected.
Step 4: Boot into Safe Mode
Booting into Safe Mode can help you identify and troubleshoot issues caused by conflicting software or drivers. To enter Safe Mode, press Windows + R, type msconfig, and press Enter. In the System Configuration window, navigate to the Boot tab and check the Safe boot option. Click OK and restart your computer. In Safe Mode, you can uninstall recently added software or drivers that may have caused the error.
Step 5: Disconnect Unnecessary External Devices
External devices can sometimes interfere with your system. Disconnect all unnecessary peripherals like USB drives, external hard disks, printers, or cameras. Once done, restart your computer to check if the error persists. If the error does not occur after removing these devices, reconnect them one at a time to identify the device causing the issue.
Step 6: Perform a Clean Boot
A clean boot can help you determine if background programs or services are contributing to the error. To perform a clean boot, access System Configuration via the Run dialog (Windows + R). In the Services tab, check the box that says Hide all Microsoft services, then click Disable all. Next, navigate to the Startup tab and click Open Task Manager. In Task Manager, disable all startup items. After completing these steps, restart your computer to see if the KMODE_EXCEPTION_NOT_HANDLED error is resolved.
