Windows 8.1 Bad Pool Header

Hi,
Since last few days My PC is crashing randomly with blue screen saying "Bad Pool Header". Most of the times, when booting. I was able to boot and get the minidump.
Could you please look and tell me why its happening ?
Here's my minidump file:
https://onedrive.live.com/redir?resid=95A241C3BAC4C83E!29908&authkey=!AIELf_qnWY-0dy8&ithint=file%2cdmp

Hi,
After analyze your dump file, I noticed that this issue is related to the graphic card driver and NVIDIA GeForce Experience.
Please update the graphic driver and block NvBackend.exe in Startup process to see what's going on.

  • (PC and Surface 8.1)bad pool header error: remote debugging using ARM device

    Tools used:
    Microsoft Visual Studio Professional 2013
    Remote Debugger Monitor (Surface RT 8.1)
    I have successfully activated the developer license as administrator.
    I have attempted to run the test app on remote device but my pc crashes before or when reaching certification.
    So far, I have attempted to run an app software for the ARM device; however, ever since I have upgraded the surface to 8.1, I constantly get the bad pool header crash, even after successfully connecting the pc to rt device.
    is there any way I can resolve the issue so I can successfully to remote debugging?
    any help is appreciated.

  • CS6 (64 bit) crashes 'Bad Pool Header'

    Hi All,
    I just installed Photoshop CS6 International English and the 13_0_1_1 update.
    Bridge standard and 64 bit both work. CS6 standard works. CS6 64 bit crashes with a blue screen 'Bad Pool Header'.
    I reinstalled CS6 and the update. No change.
    Windows and all drivers are up to date.
    I have been using Photoshop for many years - starting with v 6. I have been using CS5 64 bit on this system since it came out with no problems. CS5 64 bit is still working with CS6 installed.
    CS6 64 bit is the only program to have ever given me this error on any computer I have ever had.
    Custom built system:
    Asus motherboard M4A78-e
    AMD Phenom 9950 quad 2.61 GHz
    8 GB 1066 MHz Corsair ram
    Ati Radeon Sapphire Vapor-X HD4890 1GB memory
    Enermax Revolution 85+ power supply
    Zalman CPU 9950 fan
    Lian-Li PC60FN case
    Windows xp professional x64 service pack 2.
    Thank you for taking the time to read about my problem and thank you in advance for any suggestions.

    Dear Mylenium,
    I can see from your profile you have been very active on this forum for many years and have undoubtedly helped too many people to count. However, your certainty and negativity belies my experience, both with CS 5 64 bit and with CS 6 Bridge 64 bit, as you can see from my initial post.
    I took your suggestion and opened the Event Viewer. There were no logs to read. I looked in the properties of each of the log types in the events window and went to windows\system32\config\ just to be sure. Is there anything I can do to trigger creatitng an event log or should I look to finding the info in some other way or place?
    Thank you for taking the time to respond.

  • Error Bad Pool Header

    I have had
    frequent crashes (windows 8)
    with the message Bad Pool Header
    Looks like tel something to do with
    the network card, it only happens
    when I'm using wifi and I'm a bit
    far from the router, with a slightly
    weaker signal.
    Is it related?
    What do I do to solve?
    My laptop is a Dell Inspiron
    14z.
    Thank you.

    Not a problem! Luckily, in this case, it appears that a kernel-dump won't be necessary.
    We have a few bug checks:
    BAD_POOL_HEADER (19)

    ^^ The pool block we're looking at within the pool page belongs to LKsc (unknown). When the owning component is unknown and it alerts to update the pooltag, it's generally a 3rd party driver causing corruption.
    We can confirm this by checking the call stack:

    ^^ The driver(s) which appeared to have attributed to the corruption are Kaspersky drivers, with
    klwfp.sys (the one that caused the pool corruption) specifically being the Network Filtering Component driver for Kaspersky.
    DRIVER_IRQL_NOT_LESS_OR_EQUAL (d1)
    This indicates that a kernel-mode driver attempted to access pageable memory at a process IRQL that was too high.
    A driver tried to access an address that is pageable (or that is completely invalid) while the IRQL was too high. This bug check is usually caused by drivers that have used improper addresses.
    Unable to load image \SystemRoot\system32\DRIVERS\klwfp.sys, Win32 error 0n2

    Probably caused by : klwfp.sys ( klwfp+6ff1 )
    ^^ Once again, the Network Filtering Component driver for Kaspersky.
    Remove and replace Kaspersky with Windows 8's built-in Windows Defender for temporary troubleshooting purposes as it appears to be causing NETBIOS conflicts:

  • BSOD with both Kernal Security Check Error and Bad Pool Header.

    All -
    I have a HP DV7 laptop with Windows 8.1. It has BSOD with both Kernal Security Check Error and Bad Pool Header.
    Despite doing all the built in HP tests, there is nothing. Using an Anker HardDrive Dock results in the identical errors on another machine.
    Bottom line, even if I could see the DMP files (which I cannot); because the machine fails to boot, there are no files to be copied.
    I have tried various AIO and UEFI disks and USB, and the laptop NEVER accepts the PREINSTALL environment. Being unable to use the Anker has never happened. I seem completely locked out of the drive. Any suggestions? Thx.
    Bruce A Ades

    Hi Texas_Bruiser
    Some required details are needed for us to help you.
    Ensure that the BIOS/UEFI has been configured to allow boot from DVD/CD or USB.
    When you attempted to boot into PREINSTALL environment (PE) by using disks or USB, we need more details about error message or what happened?
    If your computer cannot even boot into Windows PE by using installation media, we suggest you check if memory and other hardware are works properly on this computer. Also try to plug this hard disk on other computer as data volume, see if the hard disk works.
    Regards

  • Bad Pool Caller and Bad Pool Header issue

    Hi,I recently upgraded my system from Windows 8 to Windows 8.1. Since then it doesn,t start normally. Mainly give Blue screen with error Bad Pool caller, Bad pool header, Service Exception error, Driver corrupted expool. The system never hibernate or sleep. Please help. 

    Hi there
    Welcome to the HP Support Forums! It is a great place to find the help you need, both from other users, HP experts and other support personnel. I understand that after upgrading to Windows 8.1 you are experiencing various BSOD errors. I am happy to assist with this. Did this start immediately after the upgrade to Windows 8.1, or was it shortly after? Checking online for those messages, I found suggestions about conflicting drivers, multiple antivirus programs in use. Here are a few examples I found from the Microsoft support forums. Something within may be of use to you. driver expool corrupted windows 8 - answers.microsoft.comBAD_POOL_CALLER error in Windows 8.1 -  answers.microsoft.comsystem service exception error blue screen - answers.microsoft.com It may also be useful to open your own thread on the Microsoft Forums, as often the experts there are looking for dump files to look for specific causes. I hope this helps.

    If anyone could potentially help me fix this error, it'd be greatly appreciated!

     We do need the actual log file (called a DMP file) as they contain the only record of the sequence of events leading up to the crash, what drivers were
    loaded, and what was responsible.  
    We prefer at least 2 DMP files to spot trends and confirm the cause.
    Please follow our instructions for finding and uploading the files we need to help you fix your computer. They can be found here
    If you have any questions about the procedure please ask
    If you are using Blue screen view, who crashed, or a similar application, don't.  They are wrong at least as often as they are correct

  • Windows 8 crashes in boot camp.... bad pool header

    I continuously am forced to reboot window's 8 in bootcamp due to a blue screen.  The majority of time the error states "Bad_pool_header" but there are times when it is another message.

    I would point out as I did above:
    I also installed the Boot Camp special hardware.
    you are running Windows.
    Boot Camp (Assistant) partitions the drive, and in Lion downloads Windows Support software.
    Lion 10.7.4 w/ Boot Camp 4.01 is the better choce.
    With Windows you will always be on your own and need to update drivers.
    Apple isn't going to until after 8 is either  released or is finalized, and maybe only for Mountain Lion (guess based on past)

  • Bad Pool Caller on startup

    I'm getting a Bad Pool Caller and Bad Pool Header errors upon startup.
    I can't even get to the desktop or to Metro screen so I can't get any log or dump files.
    It started after I accidentally installed an older version of Norton Utilities which had compatibility errors. The PC reset itself and came up with a Blue Screen error. saying
    "Your PC ran into a problem and we need to restart, Just collection some data"
    Each time it immediately restarts.
    When I get to the Recovery screen I select advanced repair options, troubleshoot, Advanced Options, Startup options.
    I've tried safe mode and but it just keeps repeating the same thing.
    I also tried to Startup Repair but that failed too!
    I would love to get in to uninstall Norton. Can you give me any advise.

    You should first make sure that there is the latest drivers installed from the manufacturer's website.
    Have you chance to upload a memory dump to your SkyDrive drive that we can analyze what is going on?

    These were Related to
    atikmpag.sys AMD multi-vendor Miniport Driver from Advanced Micro Devices, Inc.  Yours is 2 years old.  I would install the newest driver available.
    If you continue to crash I would remove McAfee and use the built in defender in its place.

  • Please help me Solve Bad Pool Caller Error (Windows 8)

    I'm repeatedly getting "Bad Pool Caller Error" on my Windows 8 PC causing it restart again and again. Tried all I knew, nothing worked. However, I'm able to use the PC in Safe Mode (right now I'm on it). Here is the link to dump files (zipped),
    -https://onedrive.live.com/?cid=574E051B8481CE34&id=574E051B8481CE34%21231
    Thank you in advance,

    For starters you need to update to win 8.1 ASAP and you need to either remove or update your PGP (Related to PGPsdk.sys PGP Software Development Kit NT Driver from PGP Corporation.) which is dated 2005 and can not possibly work in win 8.
    Then please run driver verifier to find the under lying issue
    These crashes were related to memory corruption (probably caused by a driver). 
    Please run these two tests to verify your memory and find which driver is causing the problem.  Please run verifier  first
    If you are over-clocking anything reset to default before running these tests.
    In other words STOP!!!  
    If you do not know what this means you probably are not
    1-Driver verifier (for complete directions see our wiki here)
    2-Memtest. (You can read more about running memtest here)

    It is never a good idea to have more than one active malware application as it leads to all sorts of instability and crashing.  This is your problem.  You have Kaspersky (in my opinion a leading cause of these) and Symantec (also a huge contributor)
    I would remove them both and use the built in defender of some other malware application.
    I would remove Kaspersky and use the built in defender.
    Kaspersky is a frequent cause of BSOD's.

    Symantec  is a frequent cause of BSOD's.
