Hi JT
To fix the "IRQL_NOT_LESS_OR_EQUAL" Blue Screen of Death (BSOD) error caused by the "ntoskrnl.exe" and "wdf01000.sys" files in Windows 11, you can try the following solutions:
- Update Windows 11: Ensure that your operating system is up to date by installing the latest Windows updates. Microsoft often releases patches and fixes for known issues that can cause BSOD errors.
- Update Device Drivers: Outdated or incompatible drivers can trigger BSOD errors. Visit the manufacturer's website for each of your hardware components (such as motherboard, graphics card, network adapter) and download the latest drivers compatible with Windows 11. Install them and restart your computer.
- Run Windows Memory Diagnostic: Faulty RAM modules can lead to BSOD errors. Windows includes a built-in memory diagnostic tool that can help identify and resolve memory-related issues. To access it, follow these steps:
- Press Win + R, type "mdsched.exe", and hit Enter.
- Choose the option to restart your computer and run the memory diagnostic tool.
- Let the tool perform a thorough scan of your RAM for any errors. If it detects any problems, you may need to replace the faulty RAM module.
- Check for Disk Errors: Corrupted system files or bad sectors on your hard drive can cause BSOD errors. Use the built-in Windows Disk Check utility to scan and fix disk errors. Here's how:
- Open Command Prompt as an administrator.
- Type "chkdsk C: /f /r" (replace "C:" with the drive letter where your Windows is installed) and press Enter.
- You'll be prompted to schedule a disk check on the next system restart. Type "Y" and press Enter.
- Restart your computer, and the disk check will begin. Allow it to complete.
- Disable Overclocking: If you have overclocked your CPU, GPU, or RAM, revert the settings to their default values. Overclocking can cause system instability, leading to BSOD errors.
- Perform a Clean Boot: Sometimes, third-party software or services can conflict with the operating system, resulting in BSOD errors. Perform a clean boot to start your system with minimal drivers and services running. Here's how:
- Press Win + R, type "msconfig," and hit Enter.
- In the System Configuration window, go to the "Services" tab and check the "Hide all Microsoft services" box.
- Click "Disable all" to disable third-party services.
- Switch to the "Startup" tab and click "Open Task Manager."
- In the Task Manager, disable all startup programs.
- Close the Task Manager and click "OK" in the System Configuration window.
- Restart your computer.
