Preferred Solution: Random BSOD with error message BAD POOL CALLER/MEMORY MANAGEMENT

I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link http://downloadreimage.com/download.php. (This link will automatically start a download of Reimage that you can save to your computer.)


Hello, as my title suggests, I am getting lots of BSOD's and freezing, specifically, I've been getting Bad Pool Caller, Memory Management, Page Fault in Nonpaged area, reference by pointer, and system service exception just to name a few. These crashes and freezes happen at seemingly random times, and do not appear to be related to what I am doing, whether it be browsing the internet or gaming Here are the system specs, bought December 2010, it worked well for the first few months. Of course attracted below is the BSOD dump and system health report. Thanks for any help.

A:Many BSOD's, Bad Pool Caller, Memory Management, and freezing.

Many of these issues are being cause by your ati video card drivers and ati catalyst suite please update them from here:
AMD Graphics Drivers & Software make sure you put in all the right specs.
Also please run Memtest86 and test your ram following this tutorial:
RAM - Test with Memtest86+
and last please check your disks by running chkdsk to check for any errors.

Hi there,

I'm not sure where to begin with my troubles so I'm going to list all of them in chronological order:

1. I've been having a few BSODs the past two weeks, starting with page_fault_in_nonpaged_area. I left it alone.
2. I had installed a game that didn't work (graphics card on a laptop isn't so great) so I uninstalled it and downloaded new drivers for my graphics card. Installed those.
3. Got a virus on facebook where a person's account was hacked and they posted a link to a video where there was a virus. I got rid of the virus with AVG and by deleting all temporary internet files, cookies, everything and even scanning my computer with both AdAware and AVG in Safe Mode. So I should be clear of the virus except now my firefox doesn't work. Whenever I type anything in and push enter, nothing happens. I can browse though. I'm not sure if it's related to the Firefox profile I'm using right now, which was infected when with the facebook virus.
4. Decided to use System Restore to see if it would cause everything to go back to normal and went back to prior to the installation of the game (and getting the virus).
5. I'm now faced with two BSODs: Bad Pool Caller and Memory Management. I get them whenever I'm watching video (not youtube) on supernovatube. Obviously it's not a peripheral problem because I don't have any hooked on (except for a USB mouse). I ran Memtest86 last night and things came back clean.

I am facing random BSODs since few months. Now they have become more frequent. I tried to use driver Verifier but I couldn't boot after that. I have attached my dump files which i retrieved using SF tool. Please analyse it.
PS.: I think it is due to some issue with WiFi driver as it BSODs sometimes when I start WiFi or open utorrent. I tried refreshing PC and updating Drivers but it didn't help.

Any help would be appreciated.

A:Random BSOD bad pool caller

Uninstall Connectify - the version that you are using (cnnctfy2.sys) may have known BSOD issues, it dates from 2011 (before Win8.1 was released) and it was blamed in the latest Driver Verifier enabled memory dump.

The previous memory dump has traces of Kaspersky all over it (but is not directly blamed). So, I looked at your 3rd party drivers and I also found traces of McAfee installed. Only use 1 antivirus and one firewall at a time. They can conflict with each other and cause problems (to include BSOD's).

I suggest uninstalling both Kaspersky and McAfee and seeing if that helps.
Use Windows Defender and the Windows Firewall while testing.
Once the testing is done, feel free to reinstall one (and only one) of the security protection products (Kaspersky or M that you were using. Make sure to get the latest, Win8.1 compatible version from the developer's website.

First of all sorry for my bad english, i'm all but a native speaker.
Ever since i bought my new mainboard, GPU, EAM and CPU some years ago i get a BSOD.
Never cared about it, so i can't say if it's always the same error. Nonetheless, i'm sure it's at least often the error mentioned in the threadtitle.
BSOD occurs while gaming or browsing with Firefox or using OpenOffice, ... well it can occur whatever i'm doing.
The issue survived several reinstalls of Win7 and once even occured shortly after first start of a freshly installed Win7.

After he's finished "dumping physical memory to disk" he attempts to restart but he hangs up during this restart, so i have to turn power off and on.
Thanks in advance

Remove AVG and use MSE for testing purpose.

Revo Uninstaller:

Use Revo Uninstaller to uninstall stubborn software.

Download and install the software
Opt for Advance Mode while uninstalling which allows you to remove leftover registry.
Download Revo Uninstaller Freeware - Free and Full Download - Uninstall software, remove programs, solve uninstall problems
Microsoft Security Essentials is recommended from a strict BSOD perspective, compatibility & stability compared to other internet security software. Malwarebytes is a great combo to MSE. They are free and lightweight.

Also uninstall your existing Antivirus software before you install MSE.

Good and Free system security combination.

Do not start the free trial of Malware Bytes; remember to deselect that option when prompted.

Please uninstall Daemon Tools. It uses a driver called sptd.sys which is known to cause BSODs in Windows 7.

 SPTD Removal:
Uninstall the software using Add/Remove Programs.
Reboot the system.
Once the program is uninstalled, run sptd.sys uninstaller to remove the driver from your system.

So I've been having BSOD's frequently for the past few days and I've tried to do a little of my own investigating into the problem. My research led me to believe these were driver issues, particularly with my wifi (a wireless connection to router via Netgear WN111 adapter).

I uninstalled the device completely from my machine and cleaned out the registry files. I rebooted and reinstalled using updated drivers from the netgear site. The BSOD's still occured. The CD driver & software that the adapter came has worked perfectly well for years on Windows 7 and previously Vista. So I went back to those and still the problem continues.

I updated my creative soundblaster driver through the same methods, using unstall from device manager and then cleaning out remaining drivers using Driver Sweeper. I then installed the new drivers from the Creative website.

Same with my nVidia GEforce GTX 260 Card.

Still no cure.

So far the headers have included:

- netio.sys
- nwifi.sys
- bad_pool_caller
- IRQL_not_less_or_equal

I'm hoping one of you kind genius' would take some time to analyse my minidumps of today. I've uploaded two in one zip file.

Failing that, I'll obviously take it upon myself to try and diagnose them further, I'm just hoping someone here who is far more knowledgeable about dmp files can clear things up with a definitive direction of solution.

Thanks guys.

I have been getting BSOD and occasional crash/restarts (with no BSOD) for at least a few months now. The exact cause of this is something I have no luck pinning down since very little on my computer has changed hardware wise and according to the device manager all my drivers are up to date :/

I have also noticed that my computer tends to quite sluggish when it reboots after such a crash has occurred. Since I am little clue how to read the minidump files, I have followed the forum instructions and uploaded a zip file with all the information gather by the SF tool contained within it.

So any help that can be given would be greatly appreciated

I built this computer six weeks ago and had no problems for a month! The first sign of problems came just before Christmas with random crashes and lock-ups!
It appeared to be a video card error and I pursued that avenue for a while, even sent the card back to the manufacturer (with there approval) for replacement. In the meantime, I bought another video card (so that I can SLI them when both get here) of the same manu. and model. I installed it, updated the drivers and all seemed well... For about 2 hrs! Then I got more crashes. I downloaded MEMTEST and found that one of my 512mb RAM cards was showing errors. I moved them to a different slot and tried again... No luck, so I removed one and the errors quit in Memtest. I thought I had the problem!
Yesterday, I got this new error (the one in the header), since this one is a new type of error that I have never seen on this system, I thought I would get some help!!
The system is:
AMD Athlon 64 3500+
Abit A8N-SLI mobo
1GB RAM (Currently using 512MB)
eVGA Nvidia 7800GT Video card
DVD/CD ROM combo

The error message is:

***STOP: 0x000000c2 (0x00000007, 0x00000cd4, 0x00000000, 0xfb913b78)

Any help would be appreciated, as I have reached my level of experience!!
I have attached the last four or five minidumps. Keep in mind that the earliest ones may have occurred prior to me removing the bad RAM!

A:BSOD Bad Pool Caller Error

Here is an MS article on the 0xc2 stop message, maybe that may lead you somewhere.

You dumps point to:

nv4_mini.sys "GetUlongFromAddress: unable to read from 80562970"
^^nvidia driver.

BugCheck 10, caused by cmudau.sys
^^looks like an audio driver

BugCheck 1000007F- cause by ntoskrnl.exe
^^ likely before ram

BugCheck 4E- probably caused by memory_corruption

GetUlongFromAddress: unable to read from 80562970. caused by dxg.sys
^^not sure what dxg.sys is for

That may give you something to research. It would be good to get a few fresh dumps from AFTER taking ram out, just to be sure. I checked these in no particular order.

I recently built a full computer for the first time and ive been having some random crashes and bsod's. this happens most often when playing games or multitasking. the most frequent is the memory management, mixed with pfn list corrupt, and bad pool header. the program that crashes most frequently is battlefield 3, happens a few times a night at least. shockwave has also been crashing while using chrome.

windows has prompted me several times to do a memory check, which i have, but it says no memory problems found. i burned a disk to check the ram and let it run for about an hour and it found nothing wrong. i did a clean install of windows 7 and made sure my drivers were up to date. same problems happening. if there's any more information i can give just let me know. thanks

any help would really be appreciated!

Problem is, built a new system, mobo, ram, cru. power supply all new. Runs pretty good but highly unstable,
Anyway, the BSOD seems to happen mostly while doing updates to either windows or drivers. I suspect something to do with the ATI driver that came with mobo but i'm at a loss here as i got same bad pool header or memory management BSOD during fresh install.

I have been getting memory management BSODs left and right, but I have seen a kernal security check failure and a bad pool header. This has been happening since before I upgraded from 7 to 8, so I'm guessing it's hardware? In Win7 I started getting BSODs, mainly while playing games (since that is what I use it for mostly). Chrome also crashed a lot. I figured I put something on there I shouldn't have, so I decided to wipe it and start fresh with a my student copy of Win8.

With a clean slate (SSD and HDD formatted), the problem was still there. However, in Win8 I could see that it was a memory management error. I looked it up and learned about checking my RAM, so I ran Windows Memory Diagnostic, which didn't find any error, and memtest, which crashed every time. Tested my RAM in another system and it passed. Long story short: after RMAs and sending parts in, I'm sitting with a new motherboard and cpu, and the problem is still there.

Components and what (if anything) I've done to test them:

Old CPU: AMD FX-8150
Current CPU: AMD FX-8350
(brand new) With the new cpu but old motherboard, memtest still crashed.

Old Motherboard: Gigabyte GA-990XA-UD3
Current Motherboard: ASRock Fatali1ty 990FX Killer
(brand new) After swapping the motherboard, memtest now completes.

GPU: ASUS EAH6850 DC/2DIS/1GD5/V2 Radeon HD 6850
I don't know how to test this. I made sure the drivers were up to date.

I have been getting some BSOD's for the past month or so. These are the three errors that I have received ... Memory Management, PFN_List_Corrupt and Bad Pool Header.

To try and solve the problem I have so far swapped the hard drive and reinstalled the OS (Win7 64). I also ran Memtest 86 on my ram. It ran all night and didn't find anything but I am thinking that perhaps I should test it one chip at a time. I have 3 4GB sticks of Tri channel memory so that is why I am thinking maybe they should be tested individually.

It is possible it is a driver but I have a pretty vanilla set up so I am a bit lost. I really hope it isn't a motherboard at this point. I am pretty tech savvy but I am struggling so I came here to beg for your wisdom.

I attached the dump file as directed.

A:BSOD Memory Management, PFN_List_Corrupt and Bad Pool Header


The bugchecks you're getting mostly refer to memory. So go ahead and test the sticks individually on different slots and let us know the results.

Good day all, I hope someone can help me with a consistent BSOD problem I've had today.

Every time my Steam client starts up and attempts to download its latest update, I get a BSOD with a Bad Pool Caller (one time out of about a dozen crashes it was Bad Pool Header instead). I have tried the Steam support, but their guides are focused on the program crashing, not the whole computer and I have had no luck fixing it there.

I downloaded DM Log Collector and attached my report, but I want to point out now that Windows has not produced dmp files for any of these crashes, even though the correct options are checked in the "Startup and Recovery" settings.

Thank you kindly for any help you can offer.

PS - I'm headed to bed, I'll be back tomorrow around 7am EDT.

I didn't think much of it until I got another BSOD the next day, maybe while playing DiRT 3. The first two BSOD's gave me the Memory Management error, so I downloaded Memtest86+ and ran 7 passes with no errors.

I then got another BSOD while trying to play the Kerbal Space Program Demo and running [email protected] on both the CPU and GPU. This gave me the "Bad Pool Header" error. I tried several things after this BSOD, including flashing the motherboard BIOS to a newer version and uninstalling and reinstalling my video card drivers. I also ran a GPU memory stress test and a 15 minute Furmark stress test on the GPU, thinking it might be my problem. No issues.

I booted up the computer today thinking that my problems might be solved, and left the computer running all day with [email protected] on full on the CPU and GPU. I started the KSP Demo again and got the Page Fault BSOD within about 30 seconds of opening the game.

I'm at a loss as to what to do next. Thanks for taking the time to read through my issues and a big thanks for any help you can give.

A:BSOD Memory Management, Bad Pool Header, Page Fault

Hi waharvey.

Before doing anything else, uninstall AVG following http://www.avg.com/us-en/utilities. 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; as the installed antivirus is failing.

Let us know the results. Will decide about the further steps after seeing it.

I recently have been having constant BSODs within the past month or so that at first seemed graphics related. I am not sure what the problem is but any assistance would be greatly appreciated.

OS: Windows 7 Ultimate x64 SP1
CPU: AMD Phenom II x4 965 Deneb @ 3.4 GHz
RAM: 8GB G.Skill Ripjaw Series DDR3 1600 (4x2GB) **Originally 4GB See Below
VID: Sapphire RADEON HD 6850 1GB
HDD: 300 GB Hitachi SATA (Primary) / 1.5 TB WD Sata (Secondary)
PSU: Thermaltake Toughpower 700W PSU

Originally I had thought this to be a graphics card issue because I had a prior GeForce GTX 280 die on me. It was replaced by a GeForce GTX 460 Superclocked and I was still experiencing BSODs.

After that I ran Memtest to test my ram and it came back with no errors. I only ran the test for a few hours so I am wondering if I did not test thoroughly. I ended up purchasing another 4GB and just replacing the original RAM. The machine still continued to blue screen so I figured it wasn't a memory problem and installed the original 4GB of RAM.

I am still continuing to receive 0x1A (Memory Management) and Bad Pool Header errors. Any help that I could get would be greatly appreciated.

A:Recent BSOD errors (Memory Management/Bad Pool Header)

Typical Memtest86+ runs should be done with at least 7 consecutive passes.

Nothing here is conclusive so far. I recommend you start Driver Verifier to see if it's driver related.

So far my biggest suspicion is hardware. One of the crashes mentioned code corruption where one solitary bit was lost. Often memory failure is not the cause of solitary bit problems, but they still have the potential to do so, in which case you'll want to run Memtest more. Usually, however, this is caused by either a failing Motherboard, CPU or PSU, or one of the components are overheating.

You can check with overheating using HWInfo with Sensors only enabled. Log two 30 minute sessions: one for idle, and one for high load (gaming, benchmarks, etc.). Send to use for viewing.

Last night I was trying to troubleshoot a video issue where my monitor would stop receiving a signal anytime I changed the screen resolution. I updated the driver for my video card to the latest version, then tried changing the resoltion and now I get a constant BSOD upon startup.

stop: 0x000000c2 (0x00000099,0x86B27330,0x00000000,0x00000000)

I've attached the minidumps also.

I've done a system restore and even a full restore from backup and I am still having the issue. My next step will be to reinstall Windows, but that will be a little difficult because I installed Windows 7 from the Student download. I can create an ISO using those files, but it will be a little difficult logistically so I thought I might see if anyone else has any suggestions.

My system:
Dual Core AMD Athlon 64 X2 4400+
ATI Radeon X1250 IGP
Windows 7 32bit

Output to Sceptre 46" LCD via HDMI

Thanks for any help you can give me.

The BSOD's blame avcuwil2.sys - an Adaptec AVC-3610 USB TV Tuner driver. Go the the Adaptec website and download the latest, Windows 7 compatible driver for that device.

Additionally, there are several older drivers on the system. They should be updated from the manufacturer's website to ensure that there are no compatibility issues:

When gaming on the computer it will crash and a BSOD will come up saying Bad Pool Caller. Or just a blue screen of death saying there is a problem with your video card. I have reinstalled the drivers for this card and used older drivers however the problem still contuines. I have now put my Gigabyte GTX260 in this sytem above and all seems well at the moment plays games and passes tests with 3DMark 06.
Does this sound like a dirver or a faulty video card problem??
Also one other thing I have notcied about the disk drive is the tray that opens seems to open a bit then open fully has anyone else experinced this problem before?

I'm getting a blue screen occassionally while gaming and under heavy load(dual logged). This is happening regularly for the past week(every 1-3 hours while playing). I have not installed any new software, but I have installed new drivers for soundcard and video card and a logitech camera. I don't recall exactly if I installed these drivers as a result of getting the blue screen or if they were the cause of it. The only major changes to my pc was a new power supply within the past month. The old one died and could not maintain a high enough voltage output which caused random rebooting.
The error message on the blue screen is as follows:
A problem has been detected and windows has been shut down to prevent damage to your computer.
After that message is a generic message followed by:
Technical Information:
*** STOP: 0x000000C2 (0x00000007, 0x00000CD4, 0x0202001, 0x86323608)

The reason i suspect a problem with my sound card is when I checked the event log after my last blue screen it said the following:
Unable to start a DCOM Server: {A41AF26F-59E4-11D1-AD3A-00AA003E4F83}. The error:

Otherwise, it runs perfectly, except few crashes in almost 10 months.

I tried to google it, but didn?t find anything specific. Last thing I installed was MS Visual C++ 2010 Express, and I noticed that Ad Aware (free edition) takes unusual long time to update and long time while performing scans.

My laptop encountered a BSOD just now, with an error message BAD_POOL_CALLER. Doesn't know what it means, need help.

That time I was playing Left 4 Dead 2 with my friends through LAN, my friend (the game host) dc-ed for a while so it affects the three of us. But then he reconnects back so my other friends just reconnect into the game also. Not for my laptop though, my game is not responding and I cannot reconnect back into the game, it freezes. So I hit Ctrl+Alt+Del and I click the Sign out button. My laptop restarted and I log in back. After logging in and going to the desktop, my pc hangs and the BSOD occurs. It restarts again and back to normal. But what could have make that BSOD occurs in the first place?

What is the source of the windows disc that you are trying to install? Can you have am alternative DVD/ ISO? How old the motherboard and the BIOS version is?

Also, you may try to install Ubuntu, just to make it sure that it is not a hardware problem. Though usually a Bad Pool Caller is not a hardware issue, it is related with driver/ software.

A:BSoD - bad pool caller

Start backing up you files, clone the drive if possible, and check to see if your hard drive is under warranty.  If so, contact them for an RMA so you can replace the drive, because it is almost certainly going to fail very soon.
Edit: To clarify- BAD_POOL_CALLER means your computer is trying to protect itself from data loss, and given that you have all of those disk errors in the event viewer (from your screenshot), I'd say that's probably why.  It could also be a controller failure or just a bad SATA cable, too, but I'd still get a good backup and run diagnostics on the drive.
