The IRQL NOT LESS OR EQUAL blue screen issue is well-known in Windows 10, and it seems that it has been passed down to Windows 11.
When you encounter this stop code, think about drivers since they are the ones who are causing the problem.
BSoD error IRQL NOT LESS OR EQUAL
Of course, as with any other blue screen, it may be a hardware issue, so you should be prepared to make some adjustments there as well.
What does IRQL NOT LESS OR EQUAL stand for?
The IRQL NOT LESS OR EQUAL error code indicates a memory-related problem that occurs when a system process or a device driver requires access to a memory location but lacks the necessary permissions.
NOT LESS OR EQUAL specifies the boundary level that is outside the value, and IRQL stands for Interrupt Request Level.
So, essentially, search for any modifications you made to your system prior to this happening. This may happen if you add or replace RAM modules on your computer, for example.
How can I solve the BSoD fault IRQL NOT LESS OR EQUAL?
Use the Startup Repair first.
- To boot the OS into Recovery Mode, create a bootable disc and start Windows 11 with it, or perform a hard power off three times in a row.
- Select Troubleshoot from the drop-down menu.
- Select the Advanced tab.
- Select Startup Repair now.
- If an issue is detected, the system will attempt to resolve it. If it doesn’t detect any, you’ll get a notice saying that Startup Fix was unable to repair your computer. Select Advanced settings from the drop-down menu.
- This will return you to the main menu. Select Troubleshoot, then Advanced Options, and then Startup Settings in the new window.
- To start the computer in Safe Mode, click Restart.
- You may also choose Uninstall Updates from the preceding menu and roll back any recent update if you believe it is the source of the problem.
- You may alternatively select System Restore from the same option to restore your system to a prior restore point when this issue did not occur.
- Check whether the problem remains when the PC restarts in Safe Mode. If it doesn’t, it’s likely that a third-party program is causing the problem, and you’ll need to remove it. If it does, you’ll need to go on to the next step, which is outlined below.

2. Examine your computer’s RAM.
- From the Taskbar, click the Search icon, search memory diagnostic, and select the program from the results.
- Select the first option, Restart now, and run a troubleshooting check.
- The computer will restart and do the required RAM checks; if any issues are discovered, you will be notified and given instructions on how to resolve the issue.
Because the IRQL NOT LESS OR EQUAL error may be caused by memory issues, it’s critical to check your modules using the specialized Windows Memory Diagnostic Tool.
3. Install, remove, or revert your drivers
- From the Taskbar, click the Search icon, enter device management, and select the program from the results.
- Select any area to enlarge it (we suggest beginning with Network adapters), then right-click the driver and choose Properties from the context menu.
- Now go to the Driver tab and choose Update driver as your first option. If a better driver is found, the system will install it. If it doesn’t work, try the Roll Back Driver or Uninstall Device choices one at a time to see if they help.
The Network Adapter driver was used to illustrate this process since it is more likely to produce this issue, but you should update all drivers. Use a specialized application like DriverFix to do automatic checks for outdated or missing drivers.
4. Perform an SFC scan.
- To launch Command Prompt with full rights, click the Search icon on the Taskbar, enter cmd, and choose Run as administrator.
- To execute the command, type or paste it and hit Enter: sfc /scannow sfc /scannow sfc /s
- The scan will take a few minutes to complete, so be patient. If any system files are corrupted, the program will identify and fix them.
5. Look for faults on the hard drive.
- To launch Command Prompt with administrative privileges, click the Search icon on the Taskbar, type cmd, and then choose Run as administrator.
- To execute the command, type it in the window and press Enter: /f chkdsk C:
Although the error is often associated with memory difficulties, it may also be caused by disk troubles, so it’s not a bad idea to double-check it using the remedy above.
Because we’re interested in the system partition (which is C: by default), the program examines the C: disk on your PC, but you may change the letter if you wish to search other partitions.
6. Run a virus scan on your computer.
- Select the program from the results by pressing the Search button on the Taskbar and typing windows security.
- Select Virus & Threat Protection from the drop-down menu.
- Select Scan choices from the drop-down menu.
- Select Microsoft Defender Offline Scan from the drop-down menu and click the Scan Now button. You will be prompted to restart your computer as a result of this.
Because this issue may be caused by a virus or malware, we suggest doing a complete system scan, preferably offline, because certain threats may evade the normal full scan.
We demonstrated how to run an offline scan with Microsoft Defender in this solution, but you can also use a third-party antivirus.
7. Restart your computer.
- Select Settings from the Start menu on the Taskbar.
- From the left pane, choose Windows Update, then Advanced Options.
- Select Recovery from the drop-down menu.
- Reset your computer by pressing the Reset PC button.
- We now have two choices. The first option, Keep my files, is recommended since the second would erase all data from the system disk. If you still want to delete everything, stop now and make a backup of your data.
- Next, we suggest using the Cloud download option, but you may also use the second option if you have a Windows 11 kit.
- If all of the prerequisites are fulfilled, Windows 11 will be downloaded and reinstalled on your computer.

You may use the Reliability Monitor tool in Windows 11 to determine whether a software installation or hardware update has caused these issues. Here’s how you can do it.
