    hi folks,

    i have an acer laptop with xp home; suddenly, it keeps re-booting with the
    BSOD that says at the top "page fault in non paged area". it disappears too
    fast to read the rest - which lists a loong string of 0x00000050 .... etc.

    it boots into safe mode ok, but i don't have a clue what to do in safe mode.
    SP3 is up to date etc.

    thanks for any pointers.

    What anti-virus application or security suite is installed and is your
    subscription current? What anti-spyware applications (other than Defender)?
    What third-party firewall (if any)?

    Has a(another) Norton or McAfee application ever been installed on the
    computer (e.g., a free-trial version that came preinstalled when you bought
    it)?
    ~~~~~~~~~~~~~~~~~~~~~~~~~~~
    To see the STOP error, you'll need to change the way Windows reacts to a
    BSOD.

    Right-click on My Computer (on your desktop) | Properties | Advanced |
    Startup and recovery | Settings | System Failure | Make sure the first 2
    options here are checked but that "Automatically restart" is NOT checked |
    OK your way out and reboot.

    Alternately, look for the STOP error in Start | Settings | Control Panel |
    Administrative Tools | Event Viewer | System.

    Requested data was not in memory. An invalid system memory address was
    referenced. Defective memory (including main memory, L2 RAM cache, video
    RAM) or incompatible software (including remote control and antivirus
    software) might cause this Stop message, as may other hardware problems
    (e.g., incorrect SCSI termination or a flawed PCI card).

    The following actions might prevent an error like this from happening again:

    1. Download and install updates...for your computer from Windows Update.
    2. Scan your computer for computer viruses.
    3. Check your hard disk for errors.

    May be bad form - but I'll top post so everybody see this. On an ACER with
    page fault in non-paged area the first line of attack is to REMOVE the e-lock
    application. It may have worked when it was written but it conflicts with
    both AVG and something Microsoft updated back in 2008 or 2009

    And for those who always look at the END for any solutions:
    On an ACER with page fault in non-paged area the first line of attack is to
    REMOVE the e-lock application. It may have worked when it was written but it
    conflicts with both AVG and something Microsoft updated back in 2008 or 2009
