Windows 10: IRQL NOT LESS OR EQUL

STOPCODE IRQL LESS OR EQUL

:)

 

Stop Code "Driver IRQL not less or equal" after switching to Windows Insider Fast Ring

Hi Nikola,

Thank you for writing to Microsoft Community forum.

• What is the make and model of the machine?
  
• Are you aware of any changes that happened on the computer prior to this issue?
  

The DRIVER_IRQL_NOT_LESS_OR_EQUAL indicates that a kernel-mode driver attempted to access pageable memory at a process IRQL that was too high.

This occurs when a driver tries to access an address that is pageable (or that is completely invalid) while the IRQL was too high. This bug check is usually caused by drivers that have used improper addresses or a driver that
was trying to execute code when the code itself was paged out. Possible causes for the page fault include the following:

• The function was marked as pageable and was running at an elevated IRQL (which includes obtaining a lock).
  
• The function call was made to a function in another driver, and that driver was unloaded.
  
• The function was called by using a function pointer that was an invalid pointer.
  

I suggest you to upload the mini dump files to know the root cause of the issue and troubleshoot accordingly.

Copy the Mini Dump files from C:\Windows\Mini Dump to your Desktop, zip up the files, and upload to the Cloud. Post the link for the same, so that we can examine.

Meanwhile, you may want to try the troubleshooting steps listed in
Troubleshoot blue screen errors and check if it works for you.

Hi,

The IRQL Not Less or Equal blue screen
error likely occurs due to driver issues. This can also be caused by insufficient system resources, corrupted system files, and software conflicts.
For us to investigate the issue, please clarify the following:

• What is the make and model of your device?
• Did you make any changes prior to the issue?
• Which build and version of Windows 10 are you using? To check it, follow the steps on this
  link.
  
• Can you upload the mini dump file to your OneDrive and share again the link on this thread? Since it shown on the link that you've provided that it's no longer available.

Meanwhile, we suggest another way to troubleshoot this issue and it's by performing an in-place upgrade. It's a process of installing Windows 10 without removing the current Windows version installed on your computer. To perform an in-place
upgrade, we suggest performing the steps provided by Andre Da Costa on this
link. This will be able to
repair corrupted system files while preserving your personal files, settings, and installed applications.

Feel free to post us back with the result for further assistance.

 

IRQL GT AT SYSTEM SERVICE

Hi Philippe,

Thank you for bringing up your query on Microsoft Community.

We regret the inconvenience caused to you.

• 
  When exactly do you get this message?
  
• 
  What is the complete error message you get?
  
• 
  Are you able to boot to the desktop?
  
• 
  Have you made any changes to the computer prior to this issue?
  

A blue screen error (also called a stop error) can occur if a problem causes your PC to shut down or restart unexpectedly.

The IRQL_GT_ZERO_AT_SYSTEM_SERVICE bug check has a value of 0x0000004A. This indicates that a thread is returning to user mode from a system call when its IRQL is still above PASSIVE_LEVEL.

Let us try the following steps check if it helps.

Step 1: Initially, I suggest you to start your computer in safe mode with Networking and check if the issue appears there as well. If it does not appear in safe mode with Networking place the computer in clean boot state
to identify the culprit program running in the background creating this error.

Safe Mode is a diagnostic mode that starts your computer in a limited state. Only the basic files and drivers necessary to run Windows are started.

Refer: Start your PC in safe mode in Windows 10
