irql-not-less-or-equal-windows-10-1 IRQL_NOT_LESS_OR_EQUAL is one of the most common Windows errors.

The term IRQL is referred to as Interruption Request Line, which is a code used to signal urgent attention to any occurring error. It appears on your laptop or PC’s display with a bluescreen error showing a prompt like “Dumping physical memory to disk”. This kind of error is one of the most distressful errors in the Windows Operating system; you can encounter it anytime, even while saving a file or running an important presentation or gaming program.

IRQL_NOT_LESS_OR_EQUAL generally occurs when there is a situation where a system processor device driver tries to seek access to a memory address to which it lacks access rights. In short, to make sure you understand it clearly, it is a memory-related error in your device.

Although it is a technical error, you don’t need to worry about all the probable technical solutions. Sit back and enjoy reading the article, and I’ll guide you through the fix! I’ll take you through the reasons behind these errors and guide you with steps to solve them. So let’s start!

Why does the screen turn blue in IRQL_NOT_LESS_OR_EQUAL error?

The blue screen error, or as it is generally called the Blue screen of death(BOSD), is annoying. It causes your system to reboot while collecting some error forensics.

Here are some common reasons for IRQL blue screen error :-

  1. Your motherboard or ram is malfunctioning or is damaged
  2. Improper upgrade or downgrade of windows software.
  3. Overheating of the CPU also causes BOSD. If your CPU system is above a specific temperature, the system automatically shows this error.
  4. Incompatible driver installation also causes BOSD. If the new drivers installed reacts with the older versions, it might cause a blue screen error.
  5. Some system files are damaged or corrupt.

Familiar causes for IRQL_NOT_LESS_OR_EQUAL and its solution.

IRQL_NOT_LESS_OR_EQUAL is a memory-related error. There could be many reasons behind this type of error. The common causes which people have encountered most of the time are your best bet to go for when trying to fix it for the first time. Thus, here is a list of common causes and suggestions related to it.

  • IRQL_NOT_LESS_OR_EQUAL 3Incomplete or damaged software installation: Damaged or incomplete installation often causes this error. You might have updated your PC or laptop recently, and if it doesn’t get installed correctly or you have installed any other software programme which is causing some issue in the back-end, you’re bound to get this error. The best option for this type of cause is to check windows “Reliability Monitor”. It will show you all the installation errors or failures in the recent past.
  • Incompatible device drivers:- windows operating system has a vast range of device driver software for your device. Thus, they push a lot of generic software updates specifically for the drivers of your device but with new updates often comes compatibility issues. In turn, these compatibility issues repeatedly bring BOSD error or IRQL_NOT_LESS_OR_EQUAL error in your system. The best way to resolve this error, if it is because of device drivers incompatibility, is to roll back to the previous version.

  1.   To fix it, follow the above steps :-

  2. The best way to fix this is to run the ” DISM /Online /Cleanup-Image /CheckHealth command (run at an administrative command prompt or in an administrative PowerShell session).”
  3. If, after a successful run, the command finds anything to report,
  4. IRQL_NOT_LESS_OR_EQUAL 6 Run” DISM /Online /Cleanup-Image /restorehealth”.
  5. The above command will clean up things in your system files.
  6. Then, you have to run a system file checker until it displays fixed or nothing is found.
  7. Next, run the system file checker by typing SFC /SCANNOW
  8. If the command runs, then that should fix the IRQL error.
