A memory problem mostly causes the IRQL_NOT_LESS_OR_EQUAL error. The IRQL component refers to the "Interruption ReQuest Line", and Windows uses it to notify occurrences that need immediate attention. When a device driver asks for entry to a memory location for which it does not have the required approval or access privileges, IRQL occurs.

Because memory allocations for processes often have a fixed border, the "NOT LESS OR EQUAL" section of the error indicates that the driver tried to access an address that was either outside or larger than the boundary value.

How to Fix IRQL_NOT_LESS_OR_EQUAL Blue Screen Error?

BSOD is one of the most common errors in Windows 11. It can be quite frustrating since it starts an infinite loop of restarting your PC. You can fix the IRQL_NOT_LESS_OR_EQUAL BSOD error in Windows 11 by following these methods:

#1. Use SFC and DISM Command

This approach consists of two steps. First, you must execute the DISM (Deployment Image and Servicing Management) application to resolve any problems with your virtual machine, which is utilized to restore your system. Then, to resolve any difficulties with your installed Windows files, use the SFC (System File Checker) command.

To run the DISM tool to fix the BOSD error on your PC, follow these steps:

Step 1: Right-click on your taskbar's Start Menu. Then, choose Windows Terminal (Admin) from the drop-down menu. Then, to continue, hit the Yes button.

Step 2: Choose the chevron (downward arrow) symbol from the tab bar. Then, choose the Command Prompt option by clicking.

Step 3: To restore your system image, execute DISM /Online Cleanup-Image /RestoreHealth and press Enter.

Note: To restore your bootable backup, you must be connected to the web. In addition, the Command may download certain files in the background. Furthermore, depending on your computer and internet access speed, the DISM tool might take a few minutes to finish.

use sfc and dism command

When the DISM procedure is finished, it is time to conduct the SFC scan to resolve your current difficulties.

Step 4: To execute the SFC command on your computer, enter SFC /scannow and click Enter.

Note: The SFC scan may take a few minutes to complete. After the scan, restart your computer to check whether the issue remains.

enter sfc scannow

#2. Launch Windows Memory Diagnostic

Because the BSOD error is often shown when there is a problem with memory space, it makes complete sense to perform tests for the integrated memory to rule out any possible reasons for the problem.

To run the Windows Memory Diagnostics for solving the BSOD issue, follow these steps:

Step 1: Start by going to the Search Menu, searching for Windows Memory Diagnostics, and then selecting it from the search results list. After that, select the Open button to begin using it.

Step 2: Now, choose the Restart now and check for the problems button to restart your computer and perform diagnostics.

Step 3: To conduct the required memory tests, your computer will restart and get a thorough report if there is a problem with your memory following the restart.

#3. Update Driver by Device Manager

Whether you just updated your drivers or haven't done so in a while, this may be what's causing the problem on your PC. Roll it back to the earlier version if you recently upgraded a driver—your issue should be solved. Otherwise, you will have to ensure that each driver is updated personally if your drivers are already outdated.

Step 1: Open Device Manager by searching for it in the Search Menu.

Step 2: Find the component category you recently updated the driver and double-click it to enlarge the section. Then, double-click the item to bring up its properties.

Step 3: Then, from the properties box, choose the Driver option. Then, select the Roll Back Driver option to undo the most recent update. Click the Update Driver button if you wish to update the driver.

Step 4: To allow Windows to immediately search for drivers on its networks, click the Search automatically for drivers button.

Note: If you already have the most recent driver installed on your PC, choose to Browse my computer for drivers to navigate the file using File Explorer.

click on search automatically for drivers

After that, you need to repeat the process manually to update all your PC's drivers.
