    BSOD on startup - page_fault_in_nonpaged_area - can't access safe mode

    I've had this problem for the past couple of days. Every time I turn on my laptop I get the blue screen and it restarts. I've used the repair tool and that's got me to the point of logging in. I get the welcome message but then it shuts down and restarts and I get the blue screen again. I've tried to use safe mode and it either shows me the blue screen or logs in for a second and then shuts down. I'm using Windows 7 on a hp elite book 8570w. I think the issue may have been caused by a new update being installed automatically when I didn't have my power cable plugged in and I ran out of battery.

    this is what the blue screen says:

    A problem has been detected and windows has been shut down to prevent further damage to your computer.


    Technical information:

    ** STOP: 0x00000050 (0xFFFFFA8209F7883A, 0x0000000000000000, 0xFFFFF800049A8E30, 0x0000000000000005)

    any advise would be great, thanks in advance.

    Lets see if we can identify the problem, 0x50 in safe mode usually relates to the memory or NTFS problems.
    Please start with MemTest86+, for 8GB it could take 8-10h or more to reach at least 8 passes.
    16GB takes normally 1 day but could take up to 2 days.

    Diagnostic Test


    Run MemTest86+ to analyse your RAM. MemTest86+ - Test RAM - Windows 7 Forums


    MemTest86+ needs to be run for at least 8 complete passes for conclusive results. Set it running before you go to bed and leave it overnight. We're looking for zero errors here. Even a single error will indicate RAM failure.

    Make a photo of the result and post it.

    If errors show up you can stop the test, remove all sticks but 1 and test this single stick in each slot for 8 passes or until errors show, switch sticks and repeat.
    If errors show up and you see them a lot later, no problem, the errors don't affect the test.

    Hi Axe0,

    Many thanks for your reply. I tried a few more memory tests from the boot menu and that seemed to do the job. I restarted it a couple more times and it finally worked. I'm currently backing up all my files. If I get the same issue. I'll download Memtest.

    Thanks for your help.

    Sounds like you performed built-in memory tests, though they don't do anything regarding fixing memory problems, memory tests are only capable of diagnosing the memory to see if there is a failure somewhere but they cannot do anything more.
