    Hello, I am a novice when it comes to computers, but know enough to be dangerous. With that said, for the past several weeks I have been getting BSOD's when using my laptop and they seem associated with the win32k.sys driver. Attached are the DMP files of the two most recent crashes.

    Someone else can address your blue screen issues and dump files, but I do have a question for you.

    ---------------------------------------------------------

    Why are you running Windows 7 Professional SP1 32-bit in your computer with 8 GB of RAM?

    A 32-bit version of Windows won't make use of more than 3.25 - 3.5 GB, so there's no point in having more than 4 GB in the computer.

    In some cases, having more than 4 GB in the computer will cause a 32-bit operating system to make use of less RAM.

    That appears to be the case in your computer because your log shows it's making use of only 2.92 GB.

    You are right, it has 8 GB installed, but only 4 GB is bing used. I will have our company IT person rectify so there is only 4 GB. Thanks.

    You're welcome.

    --------------------------------------------------------------

    If that perchance is a company laptop, why don't you have the I.T. person address the blue screen issue?

    The IT person did it as a favor regarding the memory, it is a personal computer so I can't get them to work on it unfortunately.

    Okay. I wasn't sure if you owned it or if the company owned it.

    Where the blue screen error is reported is not necessarily where it first started and may not be the cause.
    Some reasons for Blue Screens
    New hardware - software installed.
    Device driver - Video driver - corrupted - faulty.
    Faulty Ram - Overheating - Dying hard drive etc.
    ======
    Run a Mem Test.
    http://www.memtest.org/
    Scroll down to 'Download (Pre-built & ISOs)'
    'Download - Pre-Compiled Bootable ISO (.zip)'

    Download the ISO file from one of the links above to your desktop.
    Then burn the ISO to a Cd.
    Start the Pc using the Cd and run the memory test overnight or for at least 8 passes.

    It is best to run a full scan on individual Ram sticks if you can.
    Or run the test but if any errors are shown - then remove all sticks of Ram and test each Ram stick one at a time.
