The Blue Screen of Death (BSOD) is one of the most dreaded errors in the Windows operating systems. Usually, it can be caused due to various errors. The KMode exception not handled is that kind of error.
This error occurs when an application interferes with other applications’ memory. As a result, it indicates faulty software or corrupted system files. Alternatively, it can be caused due to an outdated or corrupted device driver.
How to Fix KMode Exception not Handled Error Windows 10?
Generally, KMode exception not handled is a harmless error. Thus, it can be fixed by following some easy solutions. For the most part, a quick restart can help to overcome this problem. However, you can try one of the methods provided below if your error does not get resolved.
Method 1 – Disable Fast Startup
Fast Startup is a new feature introduced in Windows 10. It is somewhat similar to hibernation and “saves” the Windows’ current state on the hard disk. Therefore, it simply loads from the saved state to boot faster. However, this can actually slow down the booting process and cause certain problems. Therefore, you may face KMode exception not handled error on your Windows 10 platform. Hence, you need to disable this by following the instructions provided below.
- Restart your system and press the F11 button repeatedly. This will open the boot menu of the Windows 10 operating system.
- Here, head over to Troubleshoot and go to Advanced Options. Next, navigate to Startup Settings and select the Restart option.
- Now, select Safe Mode from the list of options. Your computer will restart once again but in the Safe Mode.
- When the computer boots up successfully, press the Windows logo button to go to the Start menu. Here, type ‘power options’ and subsequently press the Enter key on your keyboard.
- Click on ‘Choose what the power button does’ from the left menu pane. Thereafter, select ‘Change Settings currently available’ from the window.
- Now, head over to Shutdown Settings and uncheck the option for ‘Fast Startup’. Save these settings and restart your system. Check if the error is still occurring or not.
Method 2 – Update Faulty Drivers
As stated earlier, you may get the KMode exception not handled error due to a faulty driver. Hence, you need to update your existing drivers to resolve this problem. For that, follow the instructions provided below.
- Restart your system and press the F11 button repeatedly to open the Boot menu. There, go to Troubleshoot and select Startup Settings.
- Next, go to Restart and choose Safe Mode with networking. Once the computer boots up, press Windows + X buttons from your keyboard to open the Quick menu.
- Here, select Device Manager. Now, find the faulty driver from the list and right-click on it. Choose ‘Update Driver’ and select ‘Search Automatically’ in the next window.
- Now, the system will start searching for available updates for the driver. If available, follow the instructions on your screen to install the updates.
- Do this for all the drivers and restart your system. Thereafter, check if you’re still facing the error or not.
Method 3 – Run System File Checker
Alternatively, you may get the KMode exception not handled error on Windows 10 due to corrupted system files. In such cases, you need to run the pre-installed System file checker utility tool. Thus, follow the given instructions given below.
- Again, restart your system and press the F11 button to access the Boot menu. Choose Troubleshoot and go to Startup Settings.
- Now, head over to Restart and choose Safe Mode with Command Prompt.
- Here, type ‘sfc /scannow’ and press Enter. The utility will now scan and fix any problems or errors with the system files.
- Once completed, type ‘shutdown -r’ and press Enter. Your system will now reboot.
- Finally, check if your operating system is booting up normally without showing the error.
Method 4 – Run Memory Diagnostic Tool
If the above solution does not work, then you can try the Memory Diagnostic utility tool. Similar to the previous method, this is also pre-installed and available in Windows. It will help to fix any memory or RAM related issue. Hence, follow the steps given below.
- Restart and boot your computer in Safe Mode with Command Prompt. You can do this by accessing the Boot menu of Windows 10.
- Thereafter, type ‘mdsched’ and press Enter. Now, the command will be executed without showing anything on the screen. This is because the tool will automatically run during the next reboot.
- Hence, type ‘shutdown -r’ and press enter to restart your system.
- The Memory Diagnostic Tool will be executed and check for any problems with RAM. If it returns an error, then you need to consult a technician.
- In case it resolves the problem, then you should not encounter KMode exception not handled error anymore in your system.
Method 5 – Reseat RAM and Reset CMOS
Another way to fix this error is by resetting the CMOS settings and RAM of your system. While following this method, you need to open your CPU or dismantle your laptop. So, you can skip this method if you’re not comfortable doing so. If you are experienced with handling the hardware components, only then follow the instructions given below.
- Turn off your system and unplug it from the main power supply. Thereafter, take the required screwdriver to unscrew your laptop or CPU.
- If you have a laptop, you need to remove its battery first. Next, find the CMOS battery by inspecting your motherboard.
- Carefully, remove the battery and let it sit for a while. Next, take out the RAM slowly. Take an eraser and rub its connecting point to clean it.
- After that, carefully put the RAM back in its place. Make sure you hear the ‘click’ sound to indicate that it has been locked in its place.
- Finally, put back the CMOS battery as well and put your CPU or laptop together. Plug it into the power supply and start your system. Check if this has resolved your problem.
In summary, the KMode exception not handled error should be resolved after following one of the methods given above. You may have to reinstall or reset your PC from the boot menu if you’re still facing this problem. Alternatively, you can consult a professional or a technician in case it is a hardware issue.
