You’ve encountered a Blue Screen of Death that points towards Ntoskrnl.exe as the culprit. Before it got to this, you probably noticed the following symptoms:

  • Slow PC performance.
  • High CPU usage and subsequent overheating.
  • Random system reboots.

Then finally, during system boot, you receive an error message that says “ntoskrnl.exe file is missing.”

Don’t get worried much. It’s not a problem that cannot be handled. So please keep reading to find out how to get rid of the Ntoskrnl.exe BSOD.
P.S. If you don’t want to read the full article, you may simply watch a short video showing a quick fix here:

What Is Ntoskrnl.exe?

Ntoskrnl.exe (short for Windows NT operating system kernel) is an essential Windows component responsible for hardware abstraction, process and memory management, and various other system services.

It consists of:

  • Cache manager
  • Kernel
  • Memory manager
  • Executive
  • Security reference monitor
  • Scheduler (Dispatcher)

Since it’s a fundamental part of Windows, when it encounters a problem, your computer crashes and displays a BSOD. The issue could occur repeatedly. You might also get a ‘Memory management’ error code.

What Causes the Ntoskrnl.exe Error?

There’s no one thing that could be said to be the cause. The issue could be software- or hardware-related. But the possible factors include:

  1. Your device drivers are outdated, corrupt, or incompatible. This is why it is important to ensure you keep them regularly updated.
  2. Faulty RAM. Replacing the sticks should fix the issue.
  3. Your RAM and local storage may be inadequate in keeping up with the activities you carry out on your computer. This leads to frequent freezing, and subsequently to the Ntoskrnl.exe error.
  4. You overclocked your devices.
  5. Some of your system files are corrupt.

How to Fix Windows 10 BSOD Caused by Ntoskrnl.Exe

Now that we’ve seen the possible causes, let’s go ahead and present the solutions:

  1. Update your drivers
  2. Run a scan with the Windows Memory Diagnostic Tool
  3. Run the System File Checker (SFC)/CHKDSK scan
  4. Reset overclocking settings for your devices
  5. Install Windows updates
  6. Perform a system restore
  7. Check your hardware

You can perform these fixes sequentially or randomly, according to your discretion.

Let’s begin.

Fix 1: Update Your Drivers

We recommend you use Auslogics Driver Updater to scan for all outdated and faulty drivers on your PC. It will automatically install the latest manufacturer-recommended versions. The tool recognizes your system specifications, so you don’t have to worry about downloading the wrong drivers.

You could also perform the update manually through Device Manager or by visiting the official website of your device manufacturer to search for each one of your drivers. Ensure you get the versions that are compatible with your OS.

Fix 2: Run a Scan with the Windows Memory Diagnostic Tool

The BSOD could be related to a faulty memory (RAM) module. So here’s what you have to do:

  1. Close all open windows.
  2. Go to the Start menu.
  3. Type ‘Windows Memory Diagnostic’ into the search bar and then click the option when it appears in the results list.
  4. Click on the option that says ‘Restart now and check for problems (recommended).’
  5. Your system will restart, and the scan will commence. Wait for it to complete. It may take a while (could be up to an hour depending on the size of your RAM).
  6. After the scan, you’ll get the results once you log into your computer.

Resolve PC Issues with Driver Updater

Unstable PC performance is often caused by outdated or corrupt drivers. Auslogics Driver Updater diagnoses driver issues and lets you update old drivers all at once or one at a time to get your PC running smoother


Fix 3: Run the System File Checker (SFC)/CHKDSK Scan

The problem could be due to corrupt system files. An SFC scan will detect and repair them.

Follow these easy steps:

  1. Go to the Start menu.
  2. Type ‘CMD’ in the search bar and right-click on Command Prompt from the search results.
  3. Select ‘Run as administrator’ to open an elevated Command Prompt window.
  4. You will receive a User Account Control (UAC) confirmation dialog. Click the Yes button.
  5. Copy and paste ‘sfc /scannow’ in the window (make sure you don’t include the inverted commas) and press Enter on your keyboard. If you choose to type the line, there should be a space between ‘sfc’ and ‘/scannow.’
  6. Wait for the scan to complete. You will then get a report on the repairs that were achieved.

If the scan shows that some problems were unable to be fixed, run a CHKDSK scan. Here’s how:

  1. Press the Windows logo key + X combination on your keyboard to open the WinX menu.
  2. Locate Command Prompt (Admin) in the list and click on it. This will open an elevated Command Prompt.
  3. Click the Yes button when presented with the User Account Control (UAC) confirmation dialog.
  4. In the window that opens, type (or copy and paste) ‘CHKDSK /f /r’ and press Enter (don’t include the inverted commas).
  5. You may be asked whether you want the scan to be performed when next your computer boots up. Type ‘y’ and press enter.
  6. Wait for the scan to complete.

Afterwards, run the SFC scan once more.

Fix 4: Reset Overclocking Settings for Your Devices

Although overclocking is a smart way of exploiting the maximum capability of your hardware, it can also lead to overheating, hardware breakdowns, and system crashes. Stop overclocking your devices if you are experiencing the Ntoskrnl.exe error.

You can use a trusted program to change the settings. But you can also do so through BIOS/UEFI. The procedure will differ for each device. Therefore, look up the instructions on how to get it done.

Fix 5: Install Windows Updates

Follow these easy steps:

  1. Press the Windows logo key + I combination on your keyboard to open the Settings app.
  2. Click on Update and Security.
  3. Select Windows Update and then click the ‘Check for Updates’ button on the right-hand side of the window. If there are any available, windows will download and install them automatically.
  4. Restart your PC and then see if the problem has been resolved.

Fix 6: Perform a System Restore

System restore will take your OS back to a time when no issues existed. Follow these easy steps to get it done:

  1. Invoke the Run dialog by pressing the Windows logo key + R combination on your keyboard.
  2. Type ‘cpl’ in the text field and press Enter or click OK.
  3. Go to the System Protection tab and then click the System Restore… button.
  4. In the window that opens, click ‘Next’ and select a restore point.
  5. Follow the instructions displayed on the screen to complete the process.

Fix 7: Check Your Hardware

A failing RAM module or Solid State Drive (SSD) could be the cause of the error you are dealing with. Replace your hard sticks and see if the issue will be resolved.

We suggest you visit an expert to help you perform this fix.

If you have two RAM slots, you can try removing both sticks. Clean the slots, and reinsert one stick. See if that fixes the issue. If no, reinsert the other stick and try again.

If your Windows OS is installed on your SSD, reinstalling it should resolve the issue.

We hope these solutions have been of help to you.
