How to Fix ntoskrnl.exe Error on Windows 11: Step-by-Step Guide
1. Update Your Device Drivers
Outdated or incompatible device drivers are often the first suspects in ntoskrnl.exe BSOD Windows 11 errors. Updating drivers can resolve compatibility issues and prevent crashes. Begin with your graphics card, network adapter, and chipset drivers:
- Open Device Manager by right-clicking the Start button.
- Expand each hardware section, right-click the device, and select Update driver.
For identifying faulty drivers, Driver Verifier is invaluable:
- Open Command Prompt as an Administrator and enter:
verifier.exe /all
This will enable Driver Verifier, helping you locate incompatible drivers that may be behind the ntoskrnl.exe BSOD. After identifying problematic drivers, update or remove them.
2. Install Windows Updates
Windows updates often include essential fixes for known issues. Installing updates can resolve compatibility problems associated with the ntoskrnl.exe file and enhance overall system stability:
- Go to Settings > Windows Update and click Check for updates.
Ensuring that both your Windows OS and BIOS are updated can often solve persistent ntoskrnl.exe crashes.
3. Perform a Full Malware Scan
A malware infection can corrupt critical system files like ntoskrnl.exe, leading to errors and potential data breaches. Conducting a comprehensive scan using a reliable antivirus or antimalware tool can eliminate any malware-related issues:
- This proactive step protects your system and prevents future ntoskrnl.exe BSOD errors caused by compromised system files.
4. Check for Memory (RAM) Issues
Faulty RAM modules are a known cause of ntoskrnl.exe memory management errors. Conduct a Windows Memory Diagnostic test to identify any issues:
- Search for Windows Memory Diagnostic in the Start menu.
- Select Restart now and check for problems.
Windows will scan your RAM and report any errors. If any faults are detected, consider replacing the RAM module, as this can directly resolve ntoskrnl.exe crashes.
5. Run a Disk Check
Corrupted disk sectors or a failing hard drive can lead to ntoskrnl.exe system file errors. Running a disk check can identify and repair these issues:
- Open Command Prompt in Admin mode and type:
chkdsk /f
This command will scan for and fix disk-related errors that may be contributing to the ntoskrnl.exe error in Windows 11.
6. Perform a Clean Boot
Third-party software can sometimes interfere with Windows processes, causing ntoskrnl.exe crashes. By performing a clean boot, you can identify if a particular app or service is causing the issue. To perform a clean boot, check out our step-by-step guide on how to perform a clean boot in Windows 11, 10, 8, and 7.
A clean boot allows you to isolate non-Microsoft services and troubleshoot effectively by running Windows with only essential processes. This can often reveal if an incompatible application is the cause.
Advanced Solutions for Persistent ntoskrnl.exe Errors
If you’re still experiencing issues, consider these advanced fixes to troubleshoot ntoskrnl.exe BSOD Windows 11:
1. Disable TMP in BIOS
Some users have found that TMP (Trusted Platform Module) settings in BIOS can cause crashes.Also, disabling TMP may prevent ntoskrnl.exe BSOD errors related to hardware conflicts:
- Access BIOS by pressing F2, F10, or Delete during startup, and disable TMP under security settings if it’s causing issues.
2. Disable Windows Recall Feature
The Windows Recall feature can occasionally interfere with system stability. Disabling it could alleviate ntoskrnl.exe-related crashes:
- Open Command Prompt in Admin mode and type:
Dism /Online /Disable-Feature /Featurename:Recall
This command deactivates Windows Recall, helping resolve compatibility issues tied to ntoskrnl.exe.
3. Turn Off Windows CPU Boost in BIOS
Overheating is a common factor behind system instability. Also, the CPU Boost feature in BIOS, which enhances CPU performance, may lead to heat-related BSODs. Disabling CPU Boost can help if overheating is suspected:
- Access BIOS settings and locate the CPU Boost option under performance settings. Disabling this feature can stabilize your system.
4. Run System File Checker
Corrupted system files can often lead to ntoskrnl.exe BSOD errors. Use the System File Checker (SFC) to scan and repair these files:
- Open Command Prompt as Administrator and enter:
sfc /scannow
The SFC tool will automatically detect and replace corrupted files, helping restore stability to your Windows 11 system.
Final Step: Perform an In-Place Upgrade
If all else fails, consider an in-place upgrade. While, this approach repairs your Windows installation while keeping your files and applications intact, effectively fixing any persistent ntoskrnl.exe BSOD issues:
- Download the Windows 11 installation media from Microsoft’s official site.
- Run the installation tool and choose Upgrade this PC now.
Moreover, this comprehensive repair can address a range of errors, including error codes 0x0000007b, 0x000000d1, and 0x0000008e, by restoring key system files related to ntoskrnl.exe.
Conclusion
The ntoskrnl.exe error in Windows 11 is a complex issue, but with the right troubleshooting steps, you can identify and fix the root causes.
