How to fix out the error of “Driver irql is not less than or equal to”?

today I will explain to you that how to fix out the error of “Driver IRQL is not less than or equal to” in detail but for this, it is necessary that you read and understand this article from top to bottom So let’s start.

If a blue screen (also known as a blue screen of death) appears on your PC or laptop, you can usually fix it yourself. In this article, we will show you how to deal with a desktop or laptop failure.

What is actually the “IRQL driver is not less than or equal to”  error mean?

This computer system message is a Windows hardware error message. This usually happens when the hard disk no longer starts for some reason or the system only stops in the middle. Unfortunately, the reasons can be varied.

“Driver is not less than irql” may also appear during Windows installation. If you are too afraid to touch the computer, you should call a computer technician.

However, the error “driver irql is not less than or equal to” is very common, especially when playing or when high performance is required. This stop code usually means that the current driver conflicts between two or more hardware devices.

This conflict occurs in the memory unit (RAM), which may be caused by the driver trying to access/write to a location where read-only RAM is allocated or not allocated to the device or memory.

Visited by multiple pilots simultaneously. This will cause the system to crash and quit all memory, thus causing BSOD and then restarting on your PC.

This error is caused by an outdated or corrupted driver that caused this conflict. In games, this is usually caused by a GPU (graphics processing unit) controller or even a mouse, keyboard, gamepad, or another game controller.

Some programs, such as AVG, IObit, Avast, McAfee, and Norton, generally install drivers to control firewalls and online activities. These drivers may reject other drivers for the activity or try to change the input of other drivers, so this error occurs.

If you are playing online games (for example CS: GO, Fortnite), this error may be caused by the wrong wireless or an ethernet controller.

This BSOD error is also common on overclocked and overloaded PCs (they can also be new PCs like Surface Pro 7). Programs like MSI Afterburner can be the cause of this situation, resulting in unstable voltage and RAM frequency. RAM needs to be replaced.

How to remove the error of “drive irql is not less than or equal to”?

What are the Possible causes of this error?

How to fix out the error of “Driver irql is not less than or equal to”

There are multiple possibilities for the BIOS message “driver irql is not less than or equal to”. The message itself may point to the controller, which may be caused by a damaged hard drive. Graphics card failures or damaged memory latches also often cause problems. Finally, we have no choice but to test the possibilities again and again.

It is useful if you have another computer for this purpose, swapping hardware or testing allegedly damaged parts here.

Computer systems to which our guide applies:

How to fix out the error of “Driver irql is not less than or equal to”

  • New Windows 10
  • Windows 8
  • The Windows 8.1
  •  Old Windows 7
  • Windows Vista
  •  The Windows XP

Ready to work:

There is no clear reason for this error, which may vary. In some cases, the problem is not the hardware driver, but the hardware itself.

First, you must rule out any errors in the controller. Therefore, make sure that all the drivers for your hardware are up to date. Here you will find instructions on how to update the driver.

In general, it is recommended to install all updates for your PC.

Case 1:

One of the possible reasons for “irql is not less than or equal to” is that the hard drive is damaged. It is difficult to determine if this is the true cause. The easiest way is to remove it and test it on a working PC. If it runs correctly there, it is not the cause of the error message.

However, you can also test that all cable connections are correctly placed. Sometimes after several attempts, the system starts up, but there are still problems. This gives the impression that the hard drive is damaged, but at some point, it may turn out to be a graphics card.

In other cases, units that are not actually involved can cause problems and interfere with other units through the controller. It can also help if you unplug all drives (not just power!) And then restart your computer.

Cases 3 and 4: The graphics card or main storage unit that results in “irql driver not less than or equal to”

The graphics card and main memory are damaged and may cause incorrect data processing, which seems to be a problem on the hard drive. If the hard drive can be excluded from the possible causes, you can find the cause of these two drives, because this is usually the cause of this error.

A good start to solving this problem is to check the memory. Usually, we have two memory locks (also called RAM) on the PC, and a single damaged memory chip will cause these errors.

This is why you only need to turn off the PC, disconnect it from the power supply, and then remove one of the memory modules. After that, please try to restart. If that doesn’t work, try another lock.

Sometimes it cannot be used because the BIOS has not registered changes. Then you need to switch to the BIOS before starting and resetting all values. Now, if it is the main memory, it should at least be able to boot with memory locks.

Graphics card

However, the error may be on the graphics card. This happens relatively frequently. But few people have some graphics cards at home.

In this case, it will be helpful if you can get back to another computer’s graphics card in no time. The following conditions also apply here: Before replacing two computers, disconnect them from the network. Not for your own safety, but to avoid damaging the motherboard.

Cause 4 The processor heats up causing “the irql driver to be not less than or equal to”

The “irql driver is not less than or equal to” error message is generally considered a memory processing problem, although the processor may be causing it.

Therefore, problems generally occur when the temperature is too high. However, this problem is very different from the problem described so far, because it does not occur when the computer starts or cold cools down.

This is safe because it means that it is easier to isolate the errors. The cause is rarely a processor hardware failure, but rather a heat dissipation problem.

If the ventilation slots are covered, for example when working with the laptop in its duvet/cover, this can happen. Also, if the ventilation slots are covered by too much dirt/dust on the computer.

In this case, you need to clean everything and especially the computer fan.

How to update a driver

How to fix out the error of “Driver irql is not less than or equal to”

Follow our detailed instructions or a brief explanation at the bottom.

Note: If the instructions don’t work, also refer to the website of the corresponding hardware manufacturer, such as the Logitech download page or the Nvidia download page. There you can often download the latest drivers. In rare cases, these drivers are so new that they are not yet recognized by the automatic Windows driver search and therefore must be installed manually.

Step 1:

Open the Start menu by clicking or pressing the [Windows] key. Now search for “Device Manager” and click on the Control Panel result that appears.

Step 2:

You are now in Device Manager. Take a look at the categories and open the category corresponding to your hardware. In the example, the driver for the graphics card needs to be updated, right-click on the specific hardware (in this case, the Intel graphics card) and select “Properties”.

Step 3:

A new window opens. Here you can see the specific properties of your hardware. You should now be able to see the “Update Driver” option at the top of the tab.

If so, Windows will automatically search for and download new drivers, if available, and if this option is disabled, there are currently no new hardware drivers available.


Drive fast:

  • In the very beginning, you have to press the menu by [Windows] key.
  • Then enter “Device Manager”. Click the result to open Device Manager in Control Panel
  • Find the hardware (for example, the graphics card) for which you want to update the drivers. The individual hardware parts are classified into categories, which you can open with a click.
  • Then right-click on the hardware and select “Properties”.
  • On the Driver tab, click Update Driver. Then it will verify and perform automatic driver update. If the field is disabled, the drivers are updated.

Professional tip:

If the problem occurs on your computer or laptop/notebook, you should try using the Reimage Plus software, which can scan the repositories and replace the damaged and missing files. This will work in most cases where the problem occurs due to system corruption.
