    Hi

    For a few weeks now I have been getting recurring BSODs. I ran a memory and disk check and the BSODs stopped for a few days. Then today I got another BSOD.

    I'm also a bit confused as to how to read a minidump file. I used the program WhoCrashed and it came up with this:

    6 crash dumps have been found and analyzed. A third party driver has been identified to be causing system crashes on your computer. It is strongly suggested that you check for updates for these drivers on their company websites. Click on the links below to search with Google for updates for these drivers:

    pwipf6.sys (pwipf6, Privacyware/PWI, Inc.)


    Not too sure how to update this particular driver.


    Thanks

    Hi, pwipf6.sys
    Relates to either Webroot firewall or Private firewall.
    Do you have one of the above installed?
    If yes, uninstall and then re-install.

    That should solve the problem but keep us updated.

    Got a new BSOD today.

    WhoCrashed says:

It is strongly suggested that you check for updates for these drivers on their company websites. Click on the links below to search with Google for updates for these drivers:

    aswmonflt.sys (avast! File System Minifilter for Windows 2003/Vista, AVAST Software)


    I'm not sure whether I should reinstall avast or what.

    Not so lucky, unfortunately. :(

    I got another one today. Windows seems to think I might have a memory problem so I ran a memory diagnostic scan and it came up with nothing.

    Whocrashed also says it's a memory problem as well. It says:

    This was probably caused by the following module: dxgmms1.sys (dxgmms1+0x1FF9B)
    Bugcheck code: 0x50 (0xFFFFFFFF920058CC, 0x0, 0xFFFFFFFF95E1FF9B, 0x0)
    Error: PAGE_FAULT_IN_NONPAGED_AREA
    file path: C:\Windows\system32\drivers\dxgmms1.sys
    product: Microsoft® Windows® Operating System
    company: Microsoft Corporation
    description: DirectX Graphics MMS
    Bug check description: This indicates that invalid system memory has been referenced.
    This appears to be a typical software driver bug and is not likely to be caused by a hardware problem.
    The crash took place in a standard Microsoft module. Your system configuration may be incorrect. Possibly this problem is caused by another driver on your system that cannot be identified at this time.

    Post the Minidump files so we can check them with the Windows debugging program.

    Create a new folder on the desktop and call it dumpfiles [or something similar]

    Look in c:\windows\minidump
    Copy the last 5 minidump files to that folder.
    Close the folder and right click on it and select Send To Compressed [zipped] Folder.
    Windows will compress the file and then save the new zipped file in the same location.

    Use the 'manage attachments' in the 'Go Advanced' reply window to upload that zip file here as an attachment.

    Some reasons for blue screens
    New hardware - software installed.
    Device driver - Video driver - corrupted - faulty.
    Faulty Ram - Overheating - Dying hard drive etc.
    As you have had 3 different blue screens in as many days - you may need to run an external memory test from a DVD.
    But we will come back to that.

    The server was busy but got enough information.
    The 2 minidumps from today - 30th Jan 2015

    aswMonFlt.sys
    Avast again - it does not like your pc!
    http://www.systemlookup.com/Drivers/635-aswMonFlt_sys.html

    I would uninstall Avast and try one of the following anti-virus programs.
    Microsoft Security Essentials.
    http://windows.microsoft.com/en-GB/windows/security-essentials-download

    Avg.
    http://free.avg.com/gb-en/homepage
    ======
    BAD_POOL_CALLER - can relate to faulty Ram - but let us know if changing the anti-virus program solves the problem.
    ======
    ======
    Edit
    I would still 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 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.

    ======
    The problem could be faulty Ram and it finds the so called weak spot in the system and that may be Avast in this case.
    So if you want to stay with Avast - run the MemTest first.

    Ok. I might need to get some help checking the ram sticks from someone. (Don't even know where they are lol) But I should be ok. I'll report back once that's all done. Thanks again!

    Just ran your first blue screen [pwipf6.sys] in the Debugging Tool and it mentioned 'Memory Management'
    Run the MemTest with all the Ram sticks in place - if it finds any errors, you may need to test each stick.
