  1. Good day,

    I am getting these stop-messages from time to time, but always when I'm playing Call of Duty: Modern Warfare 2. I've been trying out alot of things, and it seems like it doesn't crash that often anymore. It's one of these IRQL_NOT_LESS_OR_EQUAL messages. I spent alot of time to fix this. I failed, and now, I want to ask you guys for help. Here are my minidumps.

    In respect,

    Every minidump file cites your issue is with memory corruption. Therefore you’ll need to run Memtest on your RAM.

    1. Go to 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; 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.

    * Get back to us with the results.

    *** If 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?

    I'm sorry that I haven't replied yet. I was very busy lately. I'm currently burning the .iso Image to a CD. I'll post my results soon.

    Thanks for your help,

    Absolutely no need to apologize. We understand busy. :) Just follow the steps given and report when you can.

    I request this thread to be closed, since my problem suddenly disappeared. My computer isn't crashing anymore for some reason.

    But still, thanks for your help.
