Step-by-Step Solutions to Fix the IRQL NOT LESS OR EQUAL Error on Your Windows PC – PUNE.NEWS

The “IRQL NOT LESS OR EQUAL” error in Windows 10 and 11 often indicates a disruption in system file integrity, which may stem from corrupted data on your SSD or HDD. This issue can also arise from the need to repair damaged Windows OS files using built-in utilities, or it could signal that faulty RAM requires replacement. Below are seven methods to effectively address the “IRQL NOT LESS OR EQUAL” error on your Windows PC.

1. Repair Corrupted System Files with DISM & SFC

One of the primary culprits behind the “IRQL NOT LESS OR EQUAL” error is damaged system files, which can occur unexpectedly, especially after sudden shutdowns. Fortunately, Windows provides built-in tools to rectify this issue:

• Press Windows + R to open the Run dialog, type CMD, and hit OK.
• Enter the following commands one at a time, pressing Enter after each. Note that an active internet connection is required for the DISM command:

  DISM /Online /Cleanup-Image /CheckHealth
  DISM /Online /Cleanup-Image /ScanHealth
  DISM /Online /Cleanup-Image /RestoreHealth

• Next, run the System File Checker utility with the command below:

  SFC /scannow

This process will verify the integrity of your operating system, and upon completion, your system should regain stability, eliminating the “IRQL NOT LESS OR EQUAL” BSOD error.

2. Perform a System Restore

Reverting to an earlier system restore point can be one of the simplest ways to resolve the BSOD. Windows typically creates restore points automatically, so you may have one readily available. Here’s how to perform a System Restore:

• Press Windows + I to open Settings, then type System Restore in the search bar and select Create a restore point.
• In the System Properties window, click on System Restore.
• Click Next in the System Restore utility. You will see a list of available restore points.
• Select a restore point from a date when the “IRQL NOT LESS OR EQUAL” error was not present, then click Next.
• Finally, click Finish to initiate the restore process.

3. Update Windows and Drivers

Keeping both Windows and your device drivers up to date can help prevent the BSOD from recurring. Here’s how to ensure everything is current:

• Open Settings by pressing Windows + I and click on Update & Security.
• Click Check for Updates. If new updates are found, Windows will automatically download them. Restart your PC if prompted.

Additionally, consider utilizing third-party tools for driver updates, such as IOBit Driver Booster.

4. Run a Memory Test

Faulty RAM can significantly contribute to the “IRQL NOT LESS OR EQUAL” error. You can check your memory using Windows’ diagnostic tools:

• Press Windows + S, type Windows Memory Diagnostic, and select it.
• Choose Restart now and check for problems.

Your PC will restart, and the tool will scan for memory faults. For a more thorough assessment, consider using stress testing tools like MemTest86 to confirm RAM health.

5. Check Storage Health; Consider Replacing OS Drive

In many instances, the “IRQL NOT LESS OR EQUAL” error can be traced back to a failing storage drive. If the SSD or HDD containing your OS is deteriorating, it can lead to system instability. Here’s how to check your drive’s health:

• Open the Run dialog with Windows + R, type CMD, and hit OK.
• In the Command Prompt, enter:

  wmic diskdrive get status, model

You should see the status of your drive. If it reads “OK,” the drive is likely functioning properly. For a more comprehensive health check, consider using tools like CrystalDiskInfo or Hard Disk Sentinel. If your drive is failing, replacing it and reinstalling the OS may be necessary.

6. Clean Install Graphics Drivers

Reinstalling GPU drivers can sometimes resolve the BSOD. To do this effectively:

• Download the latest GPU drivers from the manufacturer’s website.
• Begin the installation process, ensuring to select the “Clean Install” option during setup. This may be labeled as “Factory Reset” for AMD GPUs or “Perform a clean install” for Intel GPUs.
• Confirm that this option is selected before proceeding with the installation.

Your PC will reboot after the driver installation, and the “IRQL NOT LESS OR EQUAL” error should be resolved if it was caused by the GPU drivers.

7. Disable Third-Party Services

Over time, various third-party services may automatically start with your PC, potentially leading to conflicts. Disabling these services can help:

• Open the Run dialog with Windows + R, type msconfig, and click OK.
• Navigate to the Services tab. Check the box for Hide all Microsoft services to avoid disabling essential services, then click Disable All.
• Ensure that you keep essential services enabled, such as those for your graphics card manufacturer and any other crucial hardware.
• Click OK and restart your PC to apply the changes.

Important Tips

• Always back up your data before making significant changes to your system, especially when performing restores or installations.
• If issues persist after trying these methods, consider seeking professional help or contacting Microsoft Support.
