How to Fix IRQL_NOT_LESS_OR_EQUAL Errors in Windows 10

Irql not less or equal is one of the more prevalent Windows stop codes. This cryptic-sounding name refers to an Interruption ReQuest Line (IRQL), which is used by PCs to notify occurrences that require immediate attention. In reality, the problem is commonly simply referred to as “IRQL,” which is a memory-related error that happens when a system process or device driver attempts to access a memory address, for which it lacks valid access rights. Because process memory allocations normally have an upper bound address, the “NOT LESS OR EQUAL” component refers to attempting to access an address that is outside that boundary value.

Reasons for the occurrence of the ‘IRQL NOT LESS OR EQUAL; Error?

When this error occurs, several possible explanations should be investigated. The best bet is to consider what has recently changed on the computer. The following are some of the possible causes:

Incompatible Device Drivers:

If users have recently updated a driver, try reverting to a previous version. Open the Device Manager (accessible by pressing Win + X), right-click on the device in issue, select Properties, navigate to the Driver tab, and click the “Roll Back Driver” button. If the button is greyed out, users will need to manually uninstall the current driver and reinstall the old version.

Incomplete or Damaged Software Installation:

Look for installation failure notifications in Reliability Monitor if users have recently installed an application or updated it. In such circumstances, uninstalling the problematic software and seeing if the problem goes away is the best bet.

Corrupt System Files:

The DISM /Online /Cleanup-Image /CheckHealth command is the best way to deal with these issues. Run DISM /Online /Cleanup-Image /RestoreHealth to clear things up if this command finds anything to report. Next, use SFC /SCANNOW to perform the system file checker until it reports nothing discovered or fixed (this may take 2 or 3 attempts). If it works, the IRQL problem is usually fixed as well.

Faulty hardware:

Users may normally see error reports in Reliability Monitor by typing perfmon/rel in the Run box, at a command line, or in PowerShell if a device is malfunctioning or failing. Disconnecting a failed or malfunctioning item from the computer is the greatest thing users can do.
