Part 3: How to Fix Ntoskrnl.exe BSOD Error?

Now, let's explore simple solutions to kick out that annoying Ntoskrnl.exe error blue screen. We'll go through each fix step by step, making it super easy to bring your computer back to life without any hassle!

Way 1: Use the Windows Memory Diagnostic

If faulty RAM is causing your ntoskrnl.exe errors, the Windows Memory Diagnostic can catch these memory issues. Follow these steps:

  • Open the Run command box by pressing Windows + R on your keyboard.
  • Type "mdsched.exe" into the Run box and press OK to open the Windows Memory Diagnostic tool.

    mdsched
  • Select "Restart now and check for problems (recommended)" to schedule a memory check on the next reboot.

    Restart now and check
  • Let your computer reboot and patiently wait as the utility scans your RAM for defects.
  • After completion, the tool will indicate if memory issues were detected or if the scan found no problems.

    memory issues
  • If your RAM check comes back with problems, use the recommendations to troubleshoot or replace faulty memory modules.

Running the Windows Memory Diagnostic rules out or resolves RAM issues that could be behind ntoskrnl.exe blue screen crashes.

Way 2: Update Your Driver to Fix ntoskrnl.exe BSOD Error

Outdated or corrupt drivers can sometimes trigger ntoskrnl.exe errors. Updating your drivers can resolve this:

  • Open the Start menu and search for "Device Manager." You can also get there by pressing Windows + I and selecting Update & Security then Device Manager.

    device manager
  • In Device Manager, expand the section for drivers you want to update, right-click the driver, and select "Update driver."

    update the driver
  • Choose to search automatically for updated driver software on your PC and on Windows Update.

    search automatically
  • Wait as Windows searches for, downloads, and installs the newest driver version for that device.
  • Repeat this process of updating drivers that are outdated, marked with a warning sign, or known to cause conflicts.

Updating drivers gets you the latest fixes and optimizations from the device manufacturer. Ensure your drivers are all up-to-date to prevent any ntoskrnl.exe blue screen crashes.

Way 3: Repair Corrupt System Files via SFC Scan

Corrupted system files can sometimes cause ntoskrnl.exe errors. System File Checker or SFC can scan for and replace damaged files:

  • Type "command prompt" into the Windows search bar. Right-click on the Command Prompt app result and select "Run as administrator."

    command prompt
  • In the elevated Command Prompt, type "sfc /scannow" and hit Enter to initiate an SFC system file scan.

    sfc and scannow
  • Administrator permission may be required. Allow the scan tool to run a thorough check of your system files and make any repairs needed.
  • The process may take some time. Wait until 100% completion of the scan for the most comprehensive system file check.
  • Restart your computer after finishing so repaired system files fully load into memory.

Scanning with SFC detects corrupt operating system files replaced to appropriate working versions by the tool. Run this to fix files possibly causing ntoskrnl.exe crashes.

Way 4: Reset Overclocking Settings to Fix Ntoskrnl.exe Error

If you have overclocked your CPU, GPU, or RAM, the instability can result in ntoskrnl.exe crashes. Resetting to default speeds may help:

  • Restart your PC and enter the BIOS setup utility by pressing the BIOS access key (F2, F10, Del) continuously when powering up and before Windows launches.
  • Navigate to sections for Processor Settings, Memory Settings, etc to locate currently enabled overclocking.
  • Load optimized default settings by finding and selecting the "Load Optimized Defaults" option in BIOS menus.

    load optimized defaults
  • Save changes and exit BIOS. The system will reboot with your CPU, GPU and memory running at standard factory speeds.
  • If the BSOD issues persist, your overclocking may not be the cause. But eliminating overclock instability is a worthwhile step in resolving ntoskrnl.exe errors.

Resetting overclocked components to default speeds removes excessive stress on critical system files like the ntoskrnl.exe kernel.

Part 4: How to Fix Ntoskrnl.exe BSOD Error in Other Ways?

If the previous fixes didn't work, don't worry. There are other simple ways you can try. Let's explore these solutions step by step to get your computer back on track!

Way 1: Repair Corrupt Data via CHKDSK Command

CHKDSK scans drives for errors and fixes logical file system issues. Using it may solve ntoskrnl.exe crashes:

  • Open an elevated Command Prompt window by searching for cmd, right-clicking Command Prompt, and selecting "Run as administrator."

    enter cmd
  • In the admin Command Prompt, type "chkdsk C: /f /r /x" and hit Enter to run CHKDSK on your main C: drive.

    type chkdsk
  • The /f parameter tells CHKDSK to fix found errors. /r recovers readable data from bad sectors. /x forces dismount first.
  • Be patient as CHKDSK scans and attempts to repair file system problems on the target drive. This process can take a while to fully complete.
  • Restart your computer after the utility finishes. Damaged file system issues linked to your ntoskrnl.exe crashes may be repaired.

CHKDSK dives deeper than SFC to fix file and directory errors that can sometimes cause unstable system behavior like ntoskrnl.exe BSODs.

Way 2: Install Windows Updates

Staying on top of the latest Windows updates can resolve ntoskrnl.exe errors triggered by bugs in older Windows builds.

  • Go to Start > Settings > Update & Security.
  • On the Windows Update tab, click Check for updates. Windows will scan for the latest updates applicable to your OS version.

    click check for updates
  • If updates are found, click "View optional updates" to see and install updates like fixes, drivers, feature updates for your specific Windows version.

    view optional updates
  • Click Install to download and apply new updates. Restart when prompted to finish updating Windows.
  • After updating, check if the recent ntoskrnl.exe crashes persist. New patches may address stability issues causing your blue screen errors.

Important hotfixes and security updates that improve system performance and reliability are distributed through Windows Update. Install the latest ones to potentially stop ntoskrnl.exe crashes.

Way 3: Run a System Restore

Reverting your Windows install to an earlier restore point without current issues can alleviate unstable behavior like ntoskrnl crashes.

  • Go to Start > Settings > System > System Protection.

    system protection
  • On the System Protection tab under Protection Settings, choose System Restore.
  • The System Restore wizard launches. Click Next, then choose a restore point from before issues began occurring.

    system restore wizard launches
  • Follow the prompts to complete restoration to the selected restore point.
  • After restoring, apps or updates installed after that date will be removed. Test if ntoskrnl.exe crashes persist - if not, a new app or update was likely the culprit.

System Restore erases changes made after the chosen restore date. Use it to undo potentially problematic Windows changes recently introduced before ntoskrnl errors started.
