Troubleshooting and Fixing IRQL_NOT_LESS_OR_EQUAL BSOD Error on Windows 11 Computer
Use DISM and SFC to Fix Damaged System Files
Damaged or corrupted system files are the most common culprits behind the blue screen stop error code IRQL NOT LESS OR EQUAL on Windows 11 computers. The only concern here is that it can happen all of a sudden, even more so if your PC tends to shut down out of nowhere or now and then.
The good news for you is that the built-in tools in Windows, specifically DISM and FSC, can help get rid of this problem and perform repairs on your current operating system.
Restore your Windows Operating System
Reverting to an early point of system restore is among the easiest and simplest ways to fix the IRQL_NOT_LESS_OR_EQUAL BSOD error. Although you might have not made one, Windows or a certain app likely created a system restore point before changes were made to the system. It means that using one of these may help restore the system to a much earlier state, or a time when the error wasn’t taking place yet.
Perform Memory Diagnostics
Since a system memory issue often causes the IRQL_NOT_LESS_OR_EQUAL BSOD error, it only makes sense that you perform diagnostics for onboard memory to help rule out other possible causes.
- Go to the Start Menu and perform a search by typing in Memory Diagnostics.
- Click on the tile for ‘Windows Memory Diagnostic’ from the search results to open the app on your PC.
- Choose the option for ‘Restart now and check for problems’ to reboot your device and run diagnostics.
Your PC will reboot and carry out the essential memory checks. Once finished, you will get a complete report after the reboot if any issue is detected.
Use Antivirus to Scan Your Windows 11 PC
You can also consider using antivirus software to scan your PC. Most of the time, a virus on the PC causes the IRQL_NOT_LESS_OR_EQUAL BSOD error. It means that you need to use a reliable antivirus program to scan your device. For this, you can choose between using the Windows Defender and third-party software to check for any malware or virus on your PC.
