    Random BSODs on a brand-new PC (ntoskrnl.exe)


    Hi,

    Bought a new computer a month ago, since then I've been having random BSODs from time to time, all related to the following: ntoskrnl.exe
    Done fresh windows install twice, those BSODs keep coming after a while.
    Recently updated bios, no results.
    Already done some hardware tests, such as:

    memtest86: running over 9 hours, no errors.
    seatool: Seagate's HDD check, passed.
    furmark: stressing the GPU, no problems.

    I'm running Driver Verifier in the background, got 3 BSODs since that.
    Razer DeathAdder mouse driver wouldn't let me go into Windows while being stressed by verifier (blue screen), so that's the only no-Microsoft driver that is not being stressed at the moment.
    (Updated that driver too, the same happened)

    Tried to analyse the .dmp files, but I guess I wasn't able to understand those.

    Hope you guys could help me, as I've had enough trying to solve this by myself.

    Thanks in advance!

    Hello rslembo, disable driver now, and test your RAM modules for possible errors.
    How to Test and Diagnose RAM Issues with Memtest86+
    Run memtest for at least 8 passes, preferably overnight.

    Uninstall BitDefender. Use Microsoft Security Essentials as your antivirus with windows inbuilt firewall, and free MBAM as the on demand scanner.
    Download, install and update those, and then run full system scans with both of them, one by one.

    Let us know the results.

    Hello, Arc.
    Thanks for the reply.

    I've just done the following steps as you suggested:

    - Disabled Driver Verifier
    - Uninstalled BitDefender
    - Scanned with MSE
    - Scanned with MBAM

    No problems with those, system is clean.

    However, I had another BSOD in the meantime:

    MEMORY_MANAGEMENT
    0x1a
    ntoskrnl.exe+7efc0

    About memtest86+, I've already done all those tests, with each memory stick separately in each memory slot.
    I guess we can assume they're all OK.
    But, just to be sure, I'll be doing all of them again from now on.

    Additional information:

    - Ran chkdsk c: /f /r with no problems related.
    - Ran sfc /scannow as Windows found a problem on "NlsData0045.dll" and could not repair it.

    - Did some hardware stress tests S&M and Prime95 with Hiren's Boot Mini XP, all ok

    Any other suggestion so we can go further with the problem?
    Thanks for the help!

    Arc, what else could I provide to you?

    Left memtest86+ overnight with one stick at channel A1, no error reports.
    I'll keep testing sticks and channels.

    I'm attaching the last dump file about the MEMORY_MANAGEMENT yesterday.
    Could you take a look at it?
    Thanks!

    Checked it all, but found nothing. According to the parameters of your data, I searched in MSDN library too, but got nothing helpful there, too.
    Code:

    Bug Check 0x1A: MEMORY_MANAGEMENT (Windows Debuggers) says, An unknown memory management error occurred.

    What can I suggest you that, you rum memtest with all the sticks together, for 8 hours. If it comes free from errors, it is definitely being caused by a driver, and verifier is unable to catch it. In this situation, better you go for a clean install.

    Driver Verifier was unable to catch or was badly executed somehow? Should give it another try?
    I'm still doing those memtest86+, almost finished one stick, no errors since.

    Doing fresh Windows install when I backup the HDD data. Maybe today or tomorrow..
