Every Windows user has had Blue Screen of Death (BSOD) issues at some point, caused by incompatible drivers or hardware failure, and Windows 10 users haven't seen it yet.
If you remember, we previously talked about how you can fix the DPC_WATCHDOG_VIOLATION error, but some Windows 10 users are reporting that they have encountered the irql_not_less_or_equal BSOD.
In this guide we will try to shed some light on how to solve this problem. As we are used to, there are many causes and just as many solutions for these Windows errors.
We even saw a similar error irql_not_less_or_equal en forma de ntoskrnl.exe which is probably caused by Realtek HiDefinition Audio drivers.
Here are some of the most common situations in which this error occurs:
- irql_not_less_or_equal ntoskrnl.exe
As a quick reminder, this executable is the kernel of the operating system and usually indicates that the problem is quite serious.
- irql_not_less_or_equal overclocking
Many gamers have confirmed that they often encounter this error after overclocking their computers. Therefore, disabling overclocking can fix this error.
- irql_not_less_or_equal CPU is overheating
If your processor is overloaded, it overheats and this can cause this error. As already stated, disable overclocking to reduce overheating.
Check if there are specific applications and programs that are stressing your computer and turn them off as soon as possible. Using a special cooling program and cooling pad can also reduce the frequency of this problem.
- irql_not_less_or_equal after RAM upgrade
Some users have reported that this BSOD error occurred shortly after upgrading their RAM. Make sure the new RAM is compatible with your device and is installed correctly.
- irql_not_less_or_equal after Windows update
In rare cases, this error can occur after installing the latest Windows update. Accordingly, uninstall the updates and check if the issue still occurs.
- irql_not_less_or_equal and memory_management
Sometimes these two BSOD errors go hand in hand. Users report that when the first error occurs, the second error follows after a reboot.
We have a special troubleshooting guide that describes how to fix MEMORY_MANAGEMENT errors in Windows 10. Follow the instructions in this guide as it may help you resolve the issue.
If you've already ruled out this driver as the cause of the error, this guide will look at some additional causes that can return this BSOD.
We'll start by looking at some quick solutions that can fix the irql_not_less_or_equal error, and then move on to more complex parameters. But first, let's see some of the causes of this error.
Like most Windows errors, the cause can be incompatibility or bad driver installation, but faulty hardware (in this case RAM or peripherals) or even a Windows update can also be blamed. .
When a device driver or kernel process tries to access an area of memory that is not allowed to be accessed, the operating system will generate an error, and the same will happen if a piece of software becomes corrupted and tries to access a location address. wrong memory.
This is a shortened version of what happens when you get an irql_not_less_or_equal error. Now let's move on to solving the problem.

update or restore
Registry restore to fix corrupt files
Check if the disk drive has errors
Run a full system scan
Perform a clean install of Windows
As I mentioned before, there are many causes and therefore different solutions to this problem. We will try to cover all the causes and address each of them individually so that you can apply the solution that best suits your needs.
Before you start, as with all Windows errors, make sure you've installed all updates and updated drivers for all your devices.
Did you know that most Windows 10 users have outdated drivers? Stay one step ahead using this guide.
Run a system update that applies all new patches for your operating system, and check for the latest drivers for your components and peripherals (visit the manufacturer's website to find out which driver is the latest for each device).
If you're having trouble updating Windows 10, check out this guide to help you fix it quickly.
Alternatively, you can check for updates to the third-party software you're using, and if you have it, try updating the BIOS.
Updating your BIOS seems daunting? Make it easy with this handy guide.
Another step that can help you avoid much of the troubleshooting process is to look in the "Event Viewer" for information about the error (to open Event Viewer, open the “Search” window, type “Event Viewer” and select the utility ).
In the window that opens, search the logs for the error you found (each log is timestamped to help you identify which device caused the problem) until you find the error.
In the details you will see where the problem occurred and you will find a recurring error caused by the same device, then this was the cause.
1. Start the computer in safe mode
Windows 10 gives users the option to start their computer in what is known as "secure boot", which is an old safe mode that we used in previous versions of the operating system.
Using this method and setting it to “minimal” settings, you can get your Windows 10 computer running with a minimal set of features, drivers, and processes.
This ensures that you are using a clean environment with no third-party drivers or applications.
This method can have one of two results: either the system will work as expected, so the problem must be one of the third-party applications or drivers you have installed on your computer, or it will crash again, causing you to it will indicate that the problem has a deeper root, perhaps in the hardware.
Once you have the answer to this question, you can go ahead and eliminate it to the exclusion of all other possibilities.
Below you will find instructions to start your Windows 10 computer in safe mode.
Hold down the Shift key and press the power button on the screen
Select the reboot option by holding down the Shift key
Select Troubleshoot > Advanced Settings > Startup Settings > and hit Restart
Wait for Windows 10 to restart and select safe mode.
Check if the problem persists.

2. Check your memory and your equipment
If step 1 has shown that the problem is not related to the software installed on your computer, you can now try debugging your computer at the hardware level.
As we mentioned at the beginning, the irql_not_less_or_equal error usually occurs when something tries to access an area of memory that you don't have permission to.
The first thing you should do in this case is check the RAM of your device. Windows offers a utility that can do this for you.
Here is how to use this utility:
Open the Search window > enter memory diagnosis » > and open the Windows memory diagnostic utility.
In the new window that opens, select one of the two available options. The first will immediately restart Windows and allow the system to scan the RAM.
If it returns an error, you already have the answer. Replace the RAM in your computer and everything should work fine.
On the other hand, if there were no errors in the scan, the problem lies elsewhere.
Not necessarily: If your motherboard BIOS has a function memory cache Disable this feature. Remember that working in a BIOS environment can be dangerous, so don't try to change other settings unless you know what they do.
Does accessing the BIOS seem like too much of a challenge? Let us help you with this amazing guide!
Checking your hardware is quite a tedious process. You will have to disconnect all connected and minor devices from your computer (which basically means everything except the mouse and keyboard) and then disable their drivers.
After rebooting, please check all controllers are still disabled and re-enable them one by one and connect the devices again.
Do not connect or turn on more than one device at a time! Only one at a time and use the computer and device once connected.
If no error appears, this driver has been reset and you can move on to the next one. Do this until you have added and activated all the devices or until a BSOD appears.
If the latter happens, it means that the problem is related to the latest included driver. Go to Safe Boot, remove the driver completely and try to download the latest version from the manufacturer and install it.
If it still doesn't work, then this driver has a compatibility issue with Windows 8.1 or Windows 10.
Optional: If the BSOD appears after a driver update, try rolling back the driver and see if the issue persists. Access to Device administrator and find the driver you want, then right-click on it and select “Properties”. In the “Driver” tab you will find the option to roll back the driver.
3. Update or restore
Windows 10 gives users the option to update their computers, which resets all settings to default. These settings will not affect any personal files you have on your computer, so you can run it without fear of losing data.
However, if you run into a critical error and Windows deletes all your files during the update process, don't panic just yet. We have written a lot about this, and our guide will surely help you to recover all your files.
System restore is a viable option if the error occurred after installing various drivers and third-party software. For this to work, you have to create a restore point before installing the software.
This is a good habit, and creating a recovery point can be a lifesaver. If you have a restore point, you can go back to that state, but any information added to the drive after the restore point was created will be deleted.
Here's how to run a system restore in Windows 10.
If system restore is turned on, follow the instructions below for Windows 10:
Go to Search > enter system properties> and open system properties.
Go to “System Protection” > click “System Restore”.
Click Next > select your preferred restore point in the new window.
After selecting your preferred restore point, hit “Next” > “Done”.
Your computer will restart and the recovery process will begin.
If system restore doesn't work, don't panic. Take a look at this helpful guide and get back to doing things right.
Windows 10 offers advanced recovery options that allow users to clean their operating system installation. If you are a Windows 10 user, you can also use the “Reset this PC” recovery option.
Go to “Settings” > “Update & Security” > click “Restore” on the left panel.
Click “Start” under “Reset this computer” > “Save your files”.
Follow the instructions on the screen to complete the reset.
If you're having trouble opening the Settings app, check out this article to resolve the issue.

4. Restore the registry to fix the corrupted files.
As stated at the beginning of this tutorial, corrupt file issues can also cause the irql_not_less_or_equal error. Accordingly, you can fix it by restoring the registry.
Note . Remember to back up your registry first if something goes wrong, so you can restore a working version of Windows.
The quickest way to do this is to use the check system file command from the command line:
Go to Home > enter cmd > right-click Command > select Run as administrator
Now enter the command sfc / scannow
Wait for the scanning process to finish and restart your computer. Any corrupted files will be replaced on reboot.
If you prefer to restore the registry automatically, you can use one of these registry cleaners. On the other hand, if you're having trouble accessing the command line as an administrator, you might want to read this guide.
Does the scan command now stop before the process is complete? Don't worry, we have a simple solution for you.
5. Check the drive for errors
Speaking of corrupted files and errors, your drive may also cause irql_not_less_or_equal error. If you have already applied the first solution in this manual and have checked the RAM memory, try also checking the disk.
In Windows 10 you can quickly run a check disk from the command line.
Run the command line as administrator and enter the command chkdsk C:/f and then press Enter. Replace C with the partition letter of your hard drive.
As a quick reminder, if you don't use the /f parameter, chkdsk displays a message that the file should be fixed, but it doesn't fix any errors. Command chkdskD:/f detects and fixes logic problems affecting your drive. To fix physical problems, run parametr /r as well.
In Windows 7, 8.1 go to hard drive > right click on the drive you want to check > select Properties > Tool. Under Error checking, click Check.
Does chkdsk give you a headache? Read this quick guide to fix any issues with it.
6. Run a full system scan
Malicious programs can cause various problems on your computer, including the irql_not_less_or_equal BSOD error. Run a full system scan to detect any malware running on your computer.
You can use the built-in Windows antivirus, Windows Defender, or one of these third-party antivirus solutions.
Here's how to perform a full system scan in Windows 10:
Go to “Start” > type “defender” > double click Windows Defender to launch the tool
Select the shield icon in the left panel
In the new window, click the Scan Options link
Select the Full Scan checkbox to run a full system scan for malware.

7. Perform a clean install of Windows
If all else fails and the error still appears even after you've exhausted all alternatives, the only thing you can do is perform a clean install of Windows.
This means that you will need a Windows installation disc or USB drive and that you will erase everything on your C: drive and install a fresh version of Windows 10, but as stated, this should be left as a last resort.
