Windows 7: BSOD Bad_Pool_Caller

BSOD Bad_Pool_Caller

I'm getting periodic BSODs (every week or 2) and every one has been a Bad_Pool_caller error. This has been ongoing for months now and it's starting to leave me with little options but to try a reformat, which I'd really like to avoid. They sometimes happen when the computer is being operating, but also have happened when the computer has been idle.

Here's what the last BSOD said:
Bad_Pool_Caller
Ox000000c2 (Ox00000007, O0000109B, Ox23232323, OxB9E9B008)

Here's some machine info:

-Win7 32bit Dell OEM (Desktop Precision T3500)
-Xeon E5507 2.27Ghz CPU
-4 GB RAM
-2 Vcards, Nvidia Quadro NVS290 and NVS420
-Add in video capture PCI card (WinFast VC100 WDM)
-Onboard Soundmax for audio

Here are steps I've taken already:
-Updated all drivers I could find, including BIOS, NIC, Vcard, Chipset, Audio etc.
-Fully patched the system
-Ran full hardware diagnostics (built-in Dell HW diagnostics at bootup). Everything passed.

Any direction on what could be causing this crash would be GREATLY appreciated!

Matt

These were caused by a memory exception. Please run these two tests to verify your memory and find which driver is causing the problem.


1-Memtest.

*Download a copy of Memtest86 and burn the ISO to a CD using Iso Recorder or another ISO burning program. Memtest86+ - Advanced Memory Diagnostic Tool

*Boot from the CD, and leave it running for at least 5 or 6 passes.

Just remember, any time Memtest reports errors, it can be either bad RAM or a bad motherboard slot.

Test the sticks individually, and if you find a good one, test it in all slots.

RAM - Test with Memtest86+



2-Driver verifier

Quote:
I'd suggest that you first backup your data and then make sure you've got access to another computer so you can contact us if problems arise. Then make a System Restore point (so you can restore the system using the Vista/Win7 Startup Repair feature).

In Windows 7 you can make a Startup Repair disk by going to Start....All Programs...Maintenance...Create a System Repair Disc - with Windows Vista you'll have to use your installation disk or the "Repair your computer" option at the top of the Safe Mode menu .

Then, here's the procedure:
- Go to Start and type in "verifier" (without the quotes) and press Enter
- Select "Create custom settings (for code developers)" and click "Next"
- Select "Select individual settings from a full list" and click "Next"
- Select everything EXCEPT FOR "Low Resource Simulation" and click "Next"
- Select "Select driver names from a list" and click "Next"
Then select all drivers NOT provided by Microsoft and click "Next"
- Select "Finish" on the next page.

Reboot the system and wait for it to crash to the Blue Screen. Continue to use your system normally, and if you know what causes the crash, do that repeatedly. The objective here is to get the system to crash because Driver Verifier is stressing the drivers out. If it doesn't crash for you, then let it run for at least 36 hours of continuous operation (an estimate on my part).

If you can't get into Windows because it crashes too soon, try it in Safe Mode.
If you can't get into Safe Mode, try using System Restore from your installation DVD to set the system back to the previous restore point that you created.

Thanks for the reply! The memory all came out clean which I expected, but always good to be sure. After running driver verifier, I was getting blue screens during the windows load. Luckily safe mode allowed me in to begin the trial and error of narrowing down the culprit. It looks to be a webcam capture card, but I'll be sure once we replace or update it and see if the BSOD's continue.

Thanks again for the assistance. I'll update the thread if theres further info, or a resolution has been found.
