Run Windows memory diagnostic tool
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.
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.
- Press Windows + R, type mdsched and click ok

Check faulty 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 for 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.
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 sees errors in the execution of driver code, it proactively creates an exception to allow that part of the driver code to be further scrutinized.
- To run Driver Verifier open command prompt as administrator,
- Type command verifier and press Enter.
- You can configure which drivers you would like to verify. The code that verifies drivers adds overhead as it runs, so try and verify the smallest number of drivers as possible.
