Windows 10 Blue screen on boot - DRIVER_IRQL_NOT_LESS_OR_EQUAL

Hi Elaf,

Thank you for posting your query in Microsoft Community.

I understand the inconvenience you are facing currently. Let me help you in resolving the issue.

I would appreciate if you can provide us the following information to help us understand the issue better.

Are you able to boot to desktop screen?

If not, as of now I would suggest that you perform Power Drain and check if you can return back to your desktop screen. To do so follow the steps below:

• Unplug the charger and remove the battery of your laptop, if using a desktop remove the power cord.
• Press and hold the Power button for 30sec
• Plug the charger/power cord and restart system.

DRIVER_IRQL_NOT_LESS_OR_EQUAL (d1)

Hello, Ben Vu



Welcome to the Microsoft Community



Thank you for your feedback. I have analyzed the blue screen log you provided.



According to the analysis of the memory dump file provided, the system encountered a blue screen of death (BSOD) when performing certain operations, and the error code is DRIVER_IRQL_NOT_LESS_OR_EQUAL (d1). This error is usually caused by the driver trying to access an invalid or paged memory address at a high priority interrupt request level (IRQL).



The modules with problems are "kbdclass.sys" and "HKKbdFltr.sys".



HKKbdFltr.sys may be a third-party keyboard filter driver, which may conflict or have compatibility issues with the system's keyboard driver (kbdclass.sys).



Based on the above analysis, you can try the following methods.



1. Try to update all related drivers, especially the keyboard driver. You can go to the keyboard manufacturer's website to download the latest driver and install it.

If HKKbdFltr.sys is a driver for a specific software or hardware, try updating or uninstalling the software/hardware driver.



2. If you have any keyboard-related third-party software installed (such as keyboard macro tools, keyboard enhancement tools, etc.), try uninstalling these software and see if the problem is solved.



I hope this information helps. If you have any questions, please let me know and I will be happy to help you further.



Best regards
