IRQL_not_less_or_equal BSOD

  1. Hey fellas.
    I'm getting the all too familiar BSOD with the heading:
    IRQL_not_less_or_equal

    Under the technical information footer, it reads:
    STOP: 0x0000000A.... (there's more, but I can't get it all)

    This will happen at random, but tends to occur more frequently when gaming.

    The screen is only up for a couple seconds before my PC reboots.
    From debugging tools to reinstalling vid drivers, I can't figure this out.
    Ideas ?

    I've uploaded five recent minidump files for reference.

    Four out of five dumps specifically cited that your issue is with memory corruption. Therefore you’ll need to run Memtest on your RAM.

    1. Go to www.memtest.org and download the latest ISO version which is 4.20. It is free and perfectly safe.

    2. Burn ISO to a CD.

    3. Place CD in your drive and reboot with CD in drive. (You might have to place your drive as first bootable in your BIOS) The test will take over.


    There is a Tutorial: How to use Memtest in our Guides and Tutorials forum; follow the instructions. There is a newer version than what is listed; use the newer. If you need to see what the Memtest screen looks like go to reply #21. The third screen is the Memtest screen.

    Step1 - Let it run for a LONG time. The rule is a minimum of 7 Passes (not hours; this test is not measured by hours); the more Passes after 7 so much the better. The only exception is if you start getting errors before 7 Passes then you can skip to Step 2.

    There are 8 individual tests per Pass. Many people will start this test before going to bed and check it the next day.

    If you have errors you have corrupted memory and it needs to be replaced.

    Step 2 – Because of errors you need to run this test per stick of RAM. Take out one and run the test. Then take that one out and put the other in and run the test. If you start getting errors before 7 Passes you know that stick is corrupted and you don’t need to run the test any further on that stick.

    Hey Route 44,

    I burned the memtest ISO file to a CDR to make a boot CD.
    Restarted computer and allowed Boot CD to initialize and start memtest.
    I ran memtest all night and the next morning it was over 12 hours in with no errors.

    So, I restored the computer back to factory settings with the windows7 CD.
    From there, I only installed the core drivers.
    Video card; ethernet port; mouse; keyboard.

    So far, this has worked and no games have crashed with the ever dreaded BSOD.

    But the real issue was never discovered, so, I'm still at a loss if it happens again other than to system restore.

    Thanks for the follow up.
    Any other ideas, just let me know.

    Route44,

    Well, my system restore fix didn't last long...
    I have attached the latest dump file.

    I ran the Windows Memory diagnostic and it came back clean.

    Any other ideas from the latest attachment ?

    Sorry for the delayed response but I was one of those who fled the Jersey Shore and my power was off as well due to Hurricane Irene.

    Two things. The first error code is 0xD1 and these are usually caused by bad drivers but also can be caused by faulty or mismatched memory.

    This dump cited the JMicron JR036X RAID Driver jraid.sys as the cause.

    The second error is 0xA and these are caused by either hardware or drivers attempting to access a higher IRQ Level than they are designed for resulting is system crashes.

    This dump cited memory corruption.

    Since Memtest shows no errors then find the voltage specs of your RAM and compare it to the voltage setting in your BIOS. Do they match? Also, do you have any mismatched memory, i.e voltage or timings?
