How To Fix ‘IRQL_NOT_LESS_OR_EQUAL’ Error In Windows 10, 8 And 7

How To

It’s one of the many Windows BSOD (Blue Screen of Death) issues, which are grouped under the umbrella term of “IRQL_NOT_LESS_OR_EQUAL.” When Windows encounters a serious problem, the Blue Screen of Death error appears.

If the PC is experiencing driver issues or a corrupted Windows Service tries to access a restricted memory region, the IRQL_NOT_LESS_OR_EQUAL error will appear. This results in the laptop going into standby mode because the current login session has been terminated, and the screen becomes blue with an error message.

Many of the problems in this category should be fixed as quickly as possible to avoid a system crash and data loss, among other things, if left unattended for an extended length of time.

How To

Problems with device drivers, such as incompatibility and bad installation, hardware issues, and virus and malware attacks, are among the most common reasons of this type of error.

In order to avoid the IRQL_NOT_LESS_OR_EQUAL issue, make sure that the Windows System and thus the device drivers are all correctly installed and up to date. This can be accomplished by regularly doing OS and third-party software system upgrades, and by regularly performing a system file backup.

Understanding the ‘IRQL_NOT_LESS_OR_EQUAL’ Error

The ‘IRQL_NOT_LESS_OR_EQUAL’ error is a stop code often encountered in Windows operating systems. It typically occurs due to issues related to memory, incompatible drivers, or faulty hardware.

The error indicates that a system process or a driver attempted to access a memory address for which it did not have appropriate permissions.

Causes of the Error

This error can be triggered by several factors:

  1. Faulty or Incompatible Drivers: The most common cause is outdated or incompatible drivers, especially after upgrading your OS.
  2. Corrupt System Files: Corruption in Windows system files can lead to this error.
  3. Faulty Hardware: Bad sectors on your hard drive or issues with your RAM can also trigger this BSOD.
  4. Software Conflicts: Sometimes, newly installed software can conflict with existing system settings or files.
  5. Overclocking: Overclocking your CPU or GPU beyond their capacities can cause this and other errors.

Diagnosing the Error

To effectively resolve the ‘IRQL_NOT_LESS_OR_EQUAL’ error, identifying the root cause is crucial. Here’s how you can diagnose the issue:

1. Check for Driver Issues

Use Windows Device Manager to check for outdated or malfunctioning drivers. Pay special attention to recently installed or updated drivers.

2. Run System File Checker

Use the System File Checker (SFC) utility to scan for and repair corrupt system files. Run sfc /scannow in the Command Prompt.

3. Check Hardware

Run a hardware diagnostic test. Tools like Windows Memory Diagnostic can check your RAM, and CHKDSK can assess your hard drive’s integrity.

4. Review Recent Changes

If the error started appearing after installing new software or hardware, this could be the culprit.

Methods To Fix ‘IRQL_NOT_LESS_OR_EQUAL’ Error In Windows 10, 8 And 7

Method 1: Boot the computer in Safe Mode to fix the IRQL_NOT_LESS_OR_EQUAL problem in Windows 10.

Step 1: Press the Shift + Power button on the screen.

Step 2: Shift-click “Restart” and hold down the shift key to reboot.

Step 3: After that, open Troubleshoot and select the Advanced option from the menu.

Step 4: Finally, click on “Restart” under the Startup Settings.

Step 5: Once the system has restarted and the Safe Mode option has been selected, you can proceed.

There may be an issue with hardware, not software or drivers or other third-party apps if the IRQL_NOT_LESS_OR_EQUAL error continues to occur.

Method 2: Processor Troubleshooting

Step 1: First, Windows gives us with a pre-installed programme and the ability to pinpoint hardware issues.

Step 2: Type “Windows Memory Diagnostic” into the Search field after pressing Windows + S.

Step 3: Select “Windows Memory Diagnostic” from the drop-down menu and click on it to begin.

Step 4: The “Restart immediately” option is one of two shown by this function; you must select it in order to do a diagnostic check. If the system is restarted, a scan will be performed immediately.

Step 5: This scan will reveal a list of faults in the RAM, suggesting that the RAM needs to be replaced.

Step 6: The system should now be working properly.

Method 3: Disabling the Memory Cache

The memory cache can be disabled in two ways:

Option 1:

Step 1: To begin, use the Basic input/output system feature by pressing the BIOS setup buttons or the F2 key.

Step 2: Go to “Memory Settings” after that. Afterwards, turn off “Memory caching feature”

Option 2: 

Step 1: Search for “Device Manager” in the search bar by pressing Windows + S.

Step 2: After clicking on Disk Drives, you’ll see the drive’s name.

Step 3: Next, open the “Policies” window on your hard drive.

Step 4: Make sure that the driver is disabled by clicking on the option that says “OK.”

Step 5: Lastly, restart your computer to put your new settings into effect.

Method 4: Unplugging all connected devices and drivers

Step 1: To begin, unhook USB sticks, flash drives, and any peripherals that are connected to the computer.

Step 2: Locate and unplug all of the system’s device drivers.

Step 3: Unplug all external devices from the computer and restart it.

Step 4: Check to see whether the error reappears after enabling each device one at a time.

Step 5: As soon as this occurs, the issue is confirmed and corrective measures must be performed

Step 6: If this doesn’t work, reboot your computer in “Safe Mode” and try the next step again.

Method 5: Repairing Registry Errors Using the Command Prompt

Step 1: Using Windows + S, type “cmd” into the search bar.

Step 2: Make sure you have administrator credentials by opening “Command Prompt” as an administrator.

Step 3: In the command prompt, type “sfc /scannow.”

Step 4: Restart the computer once scanning is complete.

Step 5: Before removing or modifying anything in your Registry, it is always a good idea to make a copy of it.

Method 6: Use System Restore.

Windows releases updates on a regular basis to keep the operating system’s functionality up to date. When an update is implemented, it may actually make things worse rather than better. Restoring your system to an earlier point before the upgrade is applied is therefore highly recommended.

To go back to a time when the PC was working properly, use a restore checkpoint that you’ve already created. A other approach should be taken if this doesn’t work.

Step 1: Open “Run” by pressing Windows key + R.

Step 2: Run “rstrui.exe” to complete the second step.

Step 3: Select “Choose a different restore point” in the “Step 3” dialogue box.

Step 4: Enter the relevant data at the appropriate checkpoint.

Step 5: Click “Finish” to complete the process.

Wait for the System Restore process to finish before restarting your computer.

Preventing the Error

Prevention is always better than cure. Here are some tips to avoid encountering this error in the future:

  1. Regularly Update Drivers: Keep your device drivers up to date to prevent compatibility issues.
  2. Install Reliable Software: Only install software from trusted sources to avoid software conflicts.
  3. Regular Hardware Checks: Regularly check your hardware for signs of wear or failure.
  4. Avoid Overclocking: Unless you’re experienced, avoid overclocking your hardware.
  5. Regular Backups: Regularly back up your data to avoid loss in case of severe errors.
