N500 Bad Pool Caller

hi folks, having a bit of trouble with my N500. It's been crashing a lot lately with a blue screen and saying "Bad Pool Caller". any ideas? I thought it was an external firewire card, but I haven't used it in days, then I thought it was the wireless card but the error log didn't show much.
Also, Windows Update crashes every time I try to open it!

Bad Pool Caller - Blue Screen of Death

Windows Blue Screens of Death (BSoDs) happen whenever your computer encounters something it doesn’t know how to process, so it shuts itself down to prevent any damage. Sometimes BSoDs happen once and you don’t see them again when you restart — however, this isnt always the case and a BSoD may show up repeatedly.
In this article we will look at issues causing a bad_pool_caller BSoD. What has happened is that a thread in the laptop's processor has made a bad pool request. This means that it’s asking to use resources that are unavailable, nonexistent, or in use by another thread. It could also mean that the pool header is corrupted — regardless of the particular error, it, like most BSoDs, is caused by driver issues.
Drivers are what makes your computer work. Every device connected to your computer, and nearly every component inside it has a software driver that determines how Windows interacts with your device. When driver issues are encountered- which is fairly common on new operating systems like Windows 8 — it can cause a lot of problems, but, fortunately, sometimes there is an easy fix.
Recently Connected and Installed Device
Try to determine which device was last connected or installed before an error appeared. Often this can be a new peripheral device. Go to Device Manager (in the Control Panel) and find the driver for the recently connected peripheral device driver. From there, you can get Windows to search for updates, you can disable it, or you can uninstall it entirely. You can also disconnect the problem device and perform a system restore to before the device was connected and supporting software was installed.
Recently Installed Program
If your drivers aren’t the problem, a recently installed program may be the issue. If you can determine what program you installed that started this, uninstall it or perform a system restore to before the program was installed, and, after a restart, you should be good to go.
System Restore
Windows 7 and earlier
Windows 8
Any further issues that cannot be resolved may require your computer to be repaired.

Every time we try to connect his Nano it causes the PC to crash with this Bad Pool Caller message.
is the BADPOOLCALLER citing a specific file, Laurita? if so, what is it called? (exact spelling please.)
if it's not citing a specific file, let's try getting a minidump to the Apple engineers for a look.
To set up your machine to capture a minidump, right click on "My Computer", select "Properties", select the "Advanced" tab, select the "Startup and Recovery" Settings button, select "small memory dump" from the popup. When it crashes, look for the MiniDump file. It's usually in the folder "C:\WINDOWS\Minidump" and is called something like Mini<number>-<number>.dmp.
Find that file and send it as an attachment to this email address.
in the email to Roy, be sure to include the following information:
- A link to the thread on Apple Discussions where the issue is being discussed
- The username you are using in the thread
- The version of iTunes you are using or trying to use
- the version of Windows you are using (mention service packs)
- A concise description of the issue you are seeing
- The exact text of the error message you are seeing

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)

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.

How to solve Bad Pool Caller issue (Windows 8.1)

I have encountered blue screen Bad Pool Caller error on my Windows 8.1 today. It happened a couple times today. I don't know why this happen.
Here is my dumps file of skydrive link.

Thanks a lot!

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.

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?

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

BSOD Bad Pool Caller Windows 8.1

Hello,
My problem is my laptop sometimes got the BSOD (that said about BAD_POOL_CALLER) when I connected my laptop to computer via WI-FI and it happened many times like 3 times until I used cable network and the problem is gone.
Product name: HP Pavilion 15 Notebook PC. Windows 8.1 64-bit
I can't verify my account so I don't know how to submit my dump file.
Thank you
PS: This is my dump file: http://1drv.ms/MPUQ7s

Hi,
After analyzing your dump file, I noticed that this issue is caused by network driver, please update it from manufacturer’s website to check the issue:

We do need the actual log files (called a DMP files) as they contain the only record of the sequence of events leading up to the crash, what drivers
were loaded, and what was responsible.
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

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)
This indicates that a pool header is corrupt.

^^ 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
*** WARNING: Unable to verify timestamp for klwfp.sys
*** ERROR: Module load completed but symbols could not be loaded for klwfp.sys
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:
