  • When you are installing a software but didn’t do it accurately. So, the system becomes panic and gives this message to beware you about the issue.



  • When you install a new hardware, and it is not compatible with the previous one, then this problem occurs.


  • The software that has been installed or uninstalled freshly can be a reason for registry corruption. The registry corruption is also a cause of BSOD.



  • BSOD is also caused because of the installation or upgradation of Windows. When system files are replaced inappropriately after the installation, then it happens.




Whenever this situation happens, you might be worried about its solution. Let me tell you some remedies for this issue. Before moving on, backup your essential data to prevent the loss of your essential files.


1- Uninstall the problematic software


Sometimes, we install software, and soon after the installation, DRIVER IRQL NOT LESS OR EQUAL appears on the screen.

By installing the software, you’ll come to know whether it was the issue or not. If it was not the matter for DRIVER IRQL NOT LESS OR EQUAL, then move on to another solution.


2- Update the drivers of your device


The drivers are the important components that connect the system with its all programs. To keep your system working, install the drivers, and update them for faster processing.


When you recently installed hardware or updated the driver and BSOD appears, be cautious. It may appear because the hardware is not in accordance with the system.


To solve the issue, again install or update the driver.


3- For updating the driver, follow the below steps


First of all, press the Windows + R, and write the “devmgmt,msc” then click ok. The device manager will open, and you can see the list of all the installed drivers.


If you see a driver with a yellow exclamation mark, it may be the problematic one. Update it or reinstall it to solve the issue.


4- The rollback option for drivers


To solve the DRIVER IRQL NOT LESS OR EQUAL, rollback the installed driver. And reinstall the previous version, might it work.


To start rollback, open device manager by “devmgmt.msc”. When you want to choose the driver that is creating the problem, right-click on it.


Then click the “properties”, then “drivers” and finally the “rollback” option.

Here a message will appear are you sure to go back to the previous version? Click the “yes” option, and when the procedure is finished, restart the Windows.


Maybe you have solved the BSOD issue. This option will be applicable if you have updated the old version to the new one, otherwise, it’s not the cause of this issue.


5- Corruption of hard drive:


This error occurs at times when you by mistake, misuse your hard drive repeatedly. There are certain ways of such misuse, like installing corrupt software, incomplete installations, or inappropriate shutdowns.


If the previous process didn’t solve your issue, then try this one.


By using “chkdsk”, you can solve the corruption issue by scanning and repairing the hard drive.


6- RAM corruption:


Any RAM corruption can cause BSOD. Sometimes, the RAM corrupts due to some issues and creates problems in the system’s normal processing.


How can you come to know that the memory is corrupt? Whenever you face beep codes on startup, computer crashes, and random computer reboots, it means RAM is corrupt.


Many application problems in Windows are often due to RAM corruption.


If you have recently installed the RAM, and soon after that, the BSOD error occurs, remove the memory. By removing it, you may resolve the issue.


If the problem fixes, it means it was due to the improper installation or incompatibility of the memory with the system.


By replacing the memory, you’ll be done with solving the problem.


If the error occurred when you didn’t install the new memory, then what would you do? Try a test on the exciting memory to find out the problem.


By doing this, you will scan the hard memory issues and other errors.

This error can also appear due to some issues in the processor. Now the question comes to mind: what type of issues?


The issues may not be that complex or tricky, but because they exist, so try to solve them. It doesn’t need to be because of a problem in the hardware of the processor.


These problems can also occur when the processor heats up a lot. You have to find out the reasons for its heating up. Maybe the ventilator slots of the processor are covered with something.


Remove the thing that is covering the CPU and creating complications. Perhaps it is heating up because the ventilators are full of dirt.


Clean the processor fans to keep it cool then the CPU will be able to work efficiently.
