    Win 7 BSODs

    If one of you guys could take a quick look at these dumps, I'd appreciate it. I can't run the BSOD script at the moment because I'm working on this remotely and the PC is offline.
    I believe this PC was a Vista to Win 7 x64 upgrade. Thanks

    The dumps are all over the place, with 3B being the most proific.
    BugCheck 19, {20, fffff8a00b2226a0, fffff8a00b2227d0, 5130315}
    Probably caused by : fltmgr.sys ( fltmgr!FltpPerformPreCallbacks+8f0 )
    BugCheck 3B, {c0000005, fffff960001935a3, fffff88005b67fe0, 0}
    Probably caused by : hardware ( win32k+c35a3 )
    BugCheck FC, {fffff8a002158dc8, ee90000067407963, fffff880046d4f70, 2}
    Probably caused by : rdbss.sys ( rdbss!RxFsdDispatch+2cf3 )
    BugCheck 3B, {c0000005, fffff9600019c913, fffff880035fae30, 0}
    Probably caused by : win32k.sys ( win32k+10c913 )
    BugCheck 1E, {ffffffffc0000005, fffff960000d8bcd, 0, 105005d}
    Probably caused by : win32k.sys ( win32k+88bcd )
    BugCheck 6B, {ffffffffc0000428, 3, 0, 0}
    Probably caused by : ntkrnlmp.exe ( nt!PspLocateSystemDll+13e )

    I would start with Memtest torule out ram first.

    Re: Win 7 BSODs

    What was the PC doing when it crashed?
    Is it anything in particular?

    I'm having a mixed opinion about these crashes to be honest.

    The pool is already corrupt at the time of the current request.
    This may or may not be due to the caller.
    The internal pool links must be walked to figure out a possible cause of
    the problem, and then special pool applied to the suspect tags or the driver
    verifier to a suspect driver.
    Arg1: 0000000000000020, a pool block header size is corrupt.
    Arg2: fffff8a00b2226a0, The pool entry we were looking for within the page.
    Arg3: fffff8a00b2227d0, The next pool entry.
    Arg4: 0000000005130315, (reserved)
    Essentially, something has corrupted a pool block header causing an inconsistency within a linked list.
    So lets look at the actual pool that is having problems.

    0: kd> !pool fffff8a00b2227d0
    Pool page fffff8a00b2227d0 region is Paged pool
     fffff8a00b222000 size:  430 previous size:    0  (Allocated)  AvN 
     fffff8a00b222430 size:   90 previous size:  430  (Allocated)  CMNb (Protected)
     fffff8a00b2224c0 size:   90 previous size:   90  (Allocated)  IoNm
     fffff8a00b222550 size:  150 previous size:   90  (Allocated)  FMfn
     fffff8a00b2226a0 size:  130 previous size:  150  (Free )  FMfn
    I would say from the looks of it, a filter driver is corrupting the pool, given that the NAME_CACHE_NODE structure appears to be corrupted I would say this looks more like a software issue.

    An exception happened while executing a system service routine.
    Arg1: 00000000c0000005, Exception code that caused the bugcheck
    Arg2: fffff960001935a3, Address of the instruction which caused the bugcheck
    Arg3: fffff88005b67fe0, Address of the context record for the exception that caused the bugcheck
    Arg4: 0000000000000000, zero.
    So we have a system service exception, this was caused by an access violation.
    The question is why? Well, lets take a look.

    fffff880`05b689c0 00000000`00000000 : 00000000`00000000 00000000`00000000 00000000`00000000 00000000`00000000 : win32k!AllocQueue+0x113
    Well... This isn't helpful at all, all we have is a Windows subsystem Kernel device driver allocating a queue of some kind.
    Any other ideas? Actually, the "Probably caused by" states it's a hardware error, I never normally listen to this, although I can see why...

    An instruction pointer misalignment, I won't go into detail about this as I actually made a blog on this here:

    Instruction pointer misalignments | bsoddebugging

    Basically I wrote that the CPU handles memory in multiples of 4th bytes, when the pointer isn't aligned with memory it can write to the 3rd byte of 5th byte which causes a bus error.
    Hence why this is usually a RAM failure.

    This is more complex, it's difficult when a lot of the functions are undocumented, networking also isn't a strong point for me so I'm not too familiar with what these routines are doing.

    It starts really with some mup routines, mup stands for Multiple UNC Provider which, AFAIK shows the path of the shared network resource such as a shared file etc.
    This is followed by csc routines, csc standard for Client Side Caching, this is probbaly related to offline file sharing that is waiting to be tranferred to the server.
    Lastly rdbss routines (Redirected Drive Buffering Subsystem), this seems to be a network interface to different parts of the Kernel including the I/O manager, memory manager and cache manager. It's essentially a mini redirector to send information to different parts of the system.

    So it would seem that a server is involved with this?
    I would say we might have a network driver causing some problems here.

    I have skipped a few files as they are 0x3Bs and 0x1Es which have very little information recorded, what is recorded seems to be very similar to our previous 0x3B.

    Arg1: ffffffffc0000428, Indicates the NT status code that caused the failure.
    Arg2: 0000000000000003, (reserved)
    Arg3: 0000000000000000
    Arg4: 0000000000000000
    This is the interesting one that mainly turned it around and seems to stem from a hardware failure.
    Lets look at that NT status code.

    0: kd> !error ffffffffc0000428
    Error code: (NTSTATUS) 0xc0000428 (3221226536) - Windows cannot verify the digital signature for this file. A recent hardware or software change might have installed a file that is signed incorrectly or damaged, or that might be malicious software from an unknown source.
    So an a file on boot up hasn't been properly digitally signed, as stated it's either corrupted, something malicious is taking place or hardware failure has corrupted the boot address.
    To be honest, the latter seems most likely.

    Well the callstack just reveals the system dynamic link libraries being initialised when be bugcheck.

    The last dump file is related to a push lock, it's very similar to a spin lock but that's for another time.

    So we seem to be at a mix here so I'll give a few suggestions.

    1. Remove Avast! and AVG as they are both installed, this isn't helpful and could easily cause crashes, I suggest replacing them with MSE.

    Download these removal tools and run them.

    avast! Uninstall Utility | Download aswClear for avast! Removal


    2. Update the
    Intel(R) PRO/1000 PCI Express Network Connection Driver as it's outdated (2009), it may be contributing to these problems.

    3. Memtest, it may well be RAM failing so memtest would be a good indicator.

    I suggest you run Memtest86 for at least 8 passes.

    Which one should I download?

    You have two options to choose from, you can either download the ISO version then burn it do a CD and boot it from there.
    The other option is downloading the auto installer for USB sticks, you then boot from that USB stick.
    Be warned though, it will format your USB then install the files needed to make it bootable so any files left over will be wiped off.

    Download it here:

    Memtest86+ - Advanced Memory Diagnostic Tool

    So how does it work?

    It works by writing a series of test patterns to most memory addresses over 9 tests, it then reads the data back to compare it for errors.

    The default pass does 9 different tests varying in access patterns and test data. A tenth pass is optional from the menu which writes all the memory in zeroes then sleeps for 90 minutes and compares it to see if any address have changed, this takes 3 hours per pass each time.

    My memtest86 isn't booting! What should I do?

    This can be caused by a number of different reasons, common ones include your BIOS not setting using the correct settings, you might want to change your boot priority order.
    Other causes include your motherboard not supporting bootable USB sticks in which case you'll need to use a CD (or floppy drive).

    Any other issues you might want to look here:

    Thanks, Wrench, I agree. I'm planning on running Memtest when I can get to the PC in person. Because the dumps are all over the place, I figured I'd ask the experts.

    Jared, all I can say is WOW!! What an analysis!

    I have no idea what it was doing. I think it was crashing when woken up from hibernation. It's only used occasionally for one program.

    I removed Avast a few days ago so you may be seeing it show up in earlier dumps. AVG isn't installed, but maybe there are some remnants.
    I think I tried updating the network driver several months ago and the installed driver is the latest ver. I found.

    It's not connected to a server OS, but some files are manually moved to another PC over the network every once in a while.
    I did notice a lot of Master Browser errors logged in Event Viewer, but haven't looked into them.

    Thanks again guys. I'll start with a memory test when I can and see what happens.
