The IRQL error may also be triggered by faulty hardware. To identify which hardware is causing the error to pop up, you will have to run a hardware diagnostic.
- For this, go to the start menu, type Memory Diagnostic in the search bar.
- Now access this tool and click on Diagnose your memory problems. As you click it, it will ask you to perform the check by either restarting the PC immediately or on the next restart.
- Select the immediate one to get going. The system will carry a scan on the memory and show you the list of problematic errors detected during the scan. To resolve this error then all you have to do is replace the piece of faulty hardware.

3. Disable Memory Caching
To fix the IRQL_NOT_LESS_OR_EQUAL error, try disabling the memory caching option. This is called BIOS memory caching.
This can be done by restarting your PC and pressing the BIOS setup keys to enter the settings screen. Mostly it is an F2 key, however, it may be different in some computers as the motherboards of different makes have their own respective keys.
Once you enter the BIOS settings look for options stating memory settings. Access these options and disable the memory caching feature.
4. Scan your PC for Malware
As mentioned above this error message can also result due to the intrusion of malicious software like malware, viruses, and spyware.
To detect and remove them from your PC, download an antivirus and perform a system scan. Remove the detected viruses and malware to resolve. Please note, antivirus installation may lower the speed of your PC.
5. Repair Registry and Fragmented Disk
Due to poor PC maintenance, you may experience registry issues. The registry stores all the activities performed on the PC including the unnecessary pieces of information like junk files, internet history, temporary files, cookies, and other flies.
Such files take up a lot of disk space. When there is not much space on the storage device, the new data is saved in fragments. This is called disk fragmentation. When this file becomes fragmented it takes time to rearrange the data and reunite it to run the fragmented file on your PC.
If not resolved, this leads to registry issues and thereby generating various PC error codes including IRQL_NOT_LESS_OR_EQUAL errors.
