  1. Laptop specs: TOSHIBA Satelite C655
    OS: Windows 7 home premium 64 bit
    BIOS: InsydeH2O Version 1.40
    Processor: Pentium r dual-core CPU T4500 @ 2.3 Ghz
    Memory; 4ghz RAM
    Integrated Mobile series GFX

    So I had like two BSODs in the past but they were like separated by 3 weeks so I didn't take notice of it. In the past 4 days however I've gotten at least one and I don't know what caused the sudden spike.

    I've tried using microsoft's debugging tools and gotten a number of "probable causes" from ftlmgr to ntfs.sys and a couple others.

    For the ones in the attachment, one was when i was loading a game and the other was when I playing. I've also had one just simply being in the desktop.

    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.

    Could you explain the purpose of burning the ISO to a cd is it for booting purposes or what? I'm confused about that part

    Burn the ISO file to a CD. That is your Memtest. Then place in CD and reboot. As the directions indicate the test will take over after you reboot.
