IRQL_NOT_LESS_OR_EQUAL Error in Windows 10

You may have come across some errors which have been occurring for as long as you can remember. Fixing them is a bit difficult and usually takes time before they finally go away. Irql_not_less_or_equal error is yet another individual from this dreadful blunder family. This error means one of three things: driver issues (could be hardware issue too), or sometimes a bad windows service maybe caused by a backup utility or a malware scanner. This error is usually shown on BSOD (Blue screen of death) with the following message:


This kind of message indicates that a driver has attempted to access a memory address that it did not have the rights to access.


Sometimes the BSOD (Blue screen of death) will specify what driver is causing this error, but not always the driver causes the error.

In case of BSOD not displaying the driver, you will have to run Driver Verifier, an application which is included in Windows to see what driver is causing IRQL_NOR LESS OR EQUAL, following are some steps to run Driver Verifier:


  1. Click on start and type verifier in the search box.
  2. Select Create Standard Settings, click next and select Automatically Select all Drivers Installed on this Computer
  3. Click next and finish.
  4. After rebooting your system if there is any faulty driver you’ll see its name on the BSOD.
  5. You now know the name of the faulty driver which can easily be uninstalled by using Device Manager.
  6. But before that you need to disable the driver verifier so that it doesn’t always check on startup.
  7. To do so, log into your windows, click start and type verifier/reset in the search box


Now as you know the name, following these steps will help you in disabling that driver:

Disabling the Faulty Driver

  1. Taking care of this problem, restart your computer in SAFE MODE so that you can avoid any further BSOD.
  2. Click on restart and search for Control Panel.
  3. After opening up the Control Panel click on Device Manager.
  4. Click on the arrow next to individual devices, right click on the device, and click Properties.
  5. Then click the details button to see the driver name. If you see any device or driver with a yellow exclamation mark, you are on the right track, but this will not necessarily be the case.
  6. You can also search for the driver by pressing Windows + F; it will help you in finding the correct location of the driver.
  7. Once you find out the faulty driver, uninstall it from the Property tab screen.
  8. As you are done uninstalling the driver, windows will attempt to install the driver itself by the information provided through the internet. This process is called Plug n Play.


Sometimes some windows service also causes this error. Let’s talk about how to solve IRQL_NOT_LESS OR_EQUAL if there is some windows service issue.

Sometimes this error will occur when a reinforcement utility or antivirus scanner rolls out improvements to Windows that it doesn’t care for. On the off chance that you’ve introduced and run such an application lately, you will need to reboot in Safe Mode and uninstall it. On the off chance that it doesn’t work, reestablish to a Restore Point that is simply before you installed that application, and utilize an alternate application.


By following above steps you will identify the reason behind IRQL_NOT_LESS_OR _EQUAL error and will be able to solve it.
