Blue screens are PC users worst nightmare but as we said they tell us or at least guide us so that we can find out what is happening on the PC so that the system does not perform as it is. must, so first of all you should know that this error can appear in two different ways: one is just the usual BSOD showing above IRQL NOT LESS OR EQUAL, but it can also appear as DRIVER IRQL NOT LESS OR EQUAL . Either way, it refers to the same thing, so let’s see what you can do to fix the problem, but first let’s see why this is happening.
IRQL BSOD NOT LESS OR EQUAL, why am I getting this error?
This blue screen has to do with IRQs, system interrupts, and since these are static assignments, it necessarily implies that there have been changes in the equipment – be it hardware or software. -, so it’s not something that comes out just because or because a hardware component of the PC has failed.
Fortunately, and since it is not a problem that a component failed, the solution to this BSOD is relatively straightforward. In any case, before using any of the techniques that we are going to list below, we recommend that you try to update the operating system to the latest version available, as it is one potential solutions that we will present to you below.
How to fix IRQL NOT LESS OR EQUAL BSOD
As we said, first make sure that the operating system is updated to the latest version; As we said before, the problem could be a change in the software, firmware or drivers of the system and since Windows updates frequently incorporate precisely this, it is always a good idea to try to update. Windows first.
To do this, click on the Start button and select Settings (the gear icon). In the window that opens, go to “Update and security” and check that you have no pending updates to download or install (obviously if this is the case, it is recommended to install them ).
Interference from third-party software
If after updating Windows the problem persists, you should stop thinking: what is the last software you installed? One of the main reasons that BSODs appear on the system is due to the installation of third party software; Antivirus software in particular is known to be one of the main causes of blue screens, so if your computer is able to start, try uninstalling the last thing you installed.
If this is not possible and you have the System Restore feature active (highly recommended, by the way) then a restore point will have been created just before installing the software, so this is not a bad idea to restore the system to get the PC back to normal. Click on the Start button and type “Recovery” to access this utility, and in the window that opens, select “Open System Restore”. This can also be done by booting from a Windows installation USB drive.
A window will open in which it will show you the possible restore points, and from where you can also see the affected programs.
Simply select the restore point you are interested in and follow the wizard. The computer will restart and run the entire process automatically, which normally doesn’t take more than a few minutes (but it depends on the speed of your PC, especially its storage).
If after that you still have the IRQL BSOD NOT LESS OR EQUAL and especially if it first appears with the word DRIVER, you must be wondering if you have recently updated a driver and as we explained at l ‘previous step, or uninstall said driver and revert to the previous version you had before, or to restore the system because when you update the drivers, restore points are also created.
In any case, if you are sure which driver you have updated and from which you started having these NOT LESS OR EQUAL IRQL BSODs, you can always try reinstalling it manually. To do this, right click on the Start button and select Device Manager. In it, display the corresponding section to find the device, right click on it and select “Update Driver”.
You can also select “Uninstall device” and restart the computer; When you restart, the operating system will detect that the device has no drivers and automatically reinstall them, so you don’t have to worry about doing it by hand.
Modifications or incorrect configuration of your equipment
When installing new hardware, it is imperative to check if it is compatible before doing so. Specifically, switching RAM or switching from single channel memory to dual channel memory (i.e. going from 1 module to 2 modules) is known to cause IRQL NOT LESS OR EQUAL. BSOD. Additionally, RAM is one of the most frequently updated hardware components, so processing old RAM modules can be a real problem.
We therefore recommend that you make sure that the hardware device you have installed is compatible with the rest of your system. If this is the case with RAM, we recommend that you try installing the modules in other sockets or using a diagnostic tool, such as Windows Memory Diagnostic.
