Update Installed Device Drivers

Drivers are essential components of your PC. They facilitate communication between the system and all installed programs and applications. They need to be installed and must be up-to-date for smooth computer operations. If you face this irql_not_less_or_equal windows 10 BSOD Error.

Check for Hard Drive Corruption

While most storage-related, 0x9 blue screen errors are caused by problems with your hard disk drivers or storage controllers. In some cases, these BSODs can be attributed to hard drive corruption. Over time, your PC can develop errors on the hard disk drive due to repeated, unintended misuse. Improper shutdowns, “hard closing” programs, corrupt or incomplete installation of software (eg. Windows Operating System), Microsoft Corporation hardware failure, and power outages can corrupt your file system and stored data. As a result, you may experience blue screen errors associated with IRQL_NOT_GREATER_OR_EQUAL.




Microsoft has included a convenient utility called “chkdsk” (“Check Disk”) to scan and repair hard disk corruption. If the previous troubleshooting steps did not resolve your 0x9 STOP error, running “chkdsk” may uncover and repair the cause of your BSOD.

How to run chkdsk 

To do this simply open Command prompt as administrator. In the command prompt window, type chkdsk c: /f /r  command and press Enter key.

After restarting, the disk checking operation should start. Wait until Windows check your disk for errors.

Test Your Memory (RAM) for Corruption

RAM is often the cause of many BSoD errors, and irql_not_less_or_equal windows 10 BSOD error is one of them. Sometimes hardware-related IRQL_NOT_GREATER_OR_EQUAL blue screen errors can be due to memory (RAM) corruption. If you are experiencing random computer reboots, receiving “beep” codes on startup, or other computer crashes (in addition to 0x9 BSOD errors), it is likely that your memory could be corrupt. In fact, nearly 10% of application crashes in Windows are due to memory corruption.

If you have just added new memory to the computer, we recommend temporarily removing it to make sure it is not the cause of your IRQL_NOT_GREATER_OR_EQUAL error. After Remove If this resolves your BSOD error. Then this will be the source of your problem, and therefore your new memory is either incompatible or bad.  In  This case, you will then need to replace your new memory modules.

If you haven’t added any new memory, the next step is to perform a diagnostic test on your computer’s existing memory. A memory test will scan for hard memory failures and intermittent errors, either of which could be causing your 0x9 blue screen of death.

In order to verify the integrity of your system’s memory, you can use Windows’ own diagnostic tool. To access this tool, type Memory Diagnostic on the Start screen and click on Diagnose your computer’s memory problems to bring up a dialog box. It will ask you to perform the check by either restarting immediately or on the next restart. Opt for the immediate one to get going.

If you find any devices with conflicts, try upgrading / removing the drivers. Shared IRQ is usually no problem, but audio and raid controllers may cause issues if they share the same IRQ.

Check other hardware

Most commonly BSOD errors are caused by a faulty RAM, but other hardware components can also cause this error to manifest. Relatively often your motherboard can cause irql not less or equal error, so you might want to check it if it’s working properly.

In addition to the motherboard, there were reports that a faulty hard drive or a graphics card can cause this error, so you might have to perform a thorough inspection of your hardware. If you don’t know how to do this, we strongly advise you to take your PC to the repair shop and ask them to this for you. In addition to faulty hardware, your recently added hardware can cause issues as well. If you installed in any new hardware, such as a new hard drive, RAM, graphics card, or anything similar, it might be incompatible with your motherboard, and that can cause this BSOD error to appear. To fix this issue, we advise you to replace any recently added hardware and see if your PC works well without it.

Resolving a faulty hardware problem

If the hardware has been added to the system recently, remove it to see if the error recurs. If existing hardware has failed, remove or replace the faulty component. You should run hardware diagnostics supplied by the system manufacturer. For details on these procedures, see the owner’s manual for your computer.

Disable the service and confirm that this resolves the error. If so, contact the manufacturer of the system service about a possible update. If the error occurs during system startup, investigate the Windows repair options. For more information, see Recovery options in Windows 10.

Use Driver Verifier to identify faulty drivers

Driver Verifier is a tool that runs in real time to examine the behavior of drivers. For example, Driver Verifier checks the use of memory resources, such as memory pools. If it see errors in the execution of driver code, it proactively creates an exception to allow that part of the driver code to be further scrutinized. The driver verifier manager is built into Windows and is available on all Windows PCs.To open Driver Verifier, click on the Start icon > Run > type “cmd.exe” and press Enter.

In the window of the Command Prompt program, type “verifier” and press Enter.
