The Kmode_Exception_Not_Handled Blue Screen of Death (BSOD) error is a dangerous system problem that can happen on Windows 10, 8, and 7 computers.

What is Kmode_Exception_Not_Handled BSOD Error?

Before we talk about how to fix the Kmode_Exception_Not_Handled BSOD error, let’s talk about what might have caused it.

  • Drivers that don’t work together or are broken: Hardware drivers that are out of date, don’t work together, or are broken are often to blame for this problem. These drivers are very important because they let your hardware and system talk to each other. If they don’t work right, the system could crash.
  • Software Conflicts: This error could be caused by two or more software tools or drivers that don’t work well together. When multiple apps try to use the same resources at the same time, the system can crash.
  • System File Corruption: This problem can also be caused by damage to system files, such as those that control how hardware works with each other.

Now, let’s look at how to fix the Kmode_Exception_Not_Handled error that causes the Blue Screen of Death (BSOD).

Method 1: Update or Roll Back Drivers

Without drivers, your computer’s tools won’t work right. The Kmode_Exception_Not_Handled error can be brought on by drivers that are too old or not the right ones. Here’s how to update drivers or roll them back:

  • To get to Safe Mode, restart your computer and keep pressing the F8 or Shift+F8 key as it starts up.
  • To get to Device Manager, right-click “Start” and select “Device Manager.”

  • Restart. Give your computer a standard restart and check to see if the BSOD problem is still there.

Method 2: Check for Windows Updates

When Windows changes, drivers are often updated and problems with the system are fixed. The Kmode_Exception_Not_Handled error can be fixed by checking for changes:

  • To get to Windows Update, click “Settings” and then “Check for Updates.” “Update & Security” is better than “Windows Update.”

  • Start the tool for Windows to test memory. Type “Windows Memory Diagnostic” into the search box in Windows and click on the app that comes up.
  • Pick how you want to turn your computer on. You’ll be asked to restart your machine and look for problems with the memory.
  • Wait until the Scan is finished. Windows will check the memory to see if it is okay. After you do this, your computer will work again.
  • Try to find trouble. After the restart, check to see if there were any memory problems. If so, your RAM may be broken and you may need to get a new one.

Method 4: Use a System File Checker (SFC)

System File Checker is a built-in tool that can look for and fix broken system files that might be causing the error:

  • Start Command Prompt as Administrator: Search for “cmd” in the Windows search bar, right-click on “Command Prompt,” and choose “Run as administrator.”

  • Restart: Turn your computer off and on again to see if the mistake is still there.

Method 5: Check for Hardware Issues

Hardware problems, like loose links or broken parts, can lead to the Kmode_Exception_Not_Handled error.

  • Disconnect External Devices. Unplug any printers or external hard drives you don’t need and keep only the ones you do.
  • Check how the hardware is hooked up. Make sure that all the gear inside the computer, like the RAM, hard drive, and graphics card, are in the right places.
  • Run Hardware Diagnostics. Many computer manufacturers include troubleshooting tools that can be used when the computer wakes up. Look at your computer’s instructions to find out how to run these tests on it.

Method 6: Restore Windows to a Previous State (Windows 10)

You can take your computer back to when Windows 10 worked well on it. This can help if the mistake happened because of new changes or updates:

  • Get Access to Ways to Get Better: Go to “Settings”, then “Updates & Security”, and then “Recovery.”
  • Click the “Get started” button next to “Restart this PC.”
  • Select “Keep my files” to update Windows without losing your own files.
  • Just do what it says on the screen to finish the reset.
