Stop BAD_POOL_CALLER 0x000000c2 Error in Xp and Windows 7

BAD_POOL_CALLER 0x000000c2 problem is a common problem with Windows operating system with many forums discussing it over and over.
I recently had my Blue screen problems with DELL XPS Laptop and it was that time when i search for this bad pool caller or bad poll header problem.But there were pointers only with no to the point solution s and this has made me to write this post.

A problem has been detected and Windows has been shut down to prevent damage to your computer.
If this is the first time you've seen this Stop error screen, restart your computer. If this screen appears again, follow these steps:

Check to make sure any new hardware or software is properly installed. If this is a new installation, ask your hardware or software manufacturer for any Windows updates you might need.

If problems continue, disable or remove any newly installed hardware or software. Disable BIOS memory options such as caching or shadowing. If you need to use Safe Mode to remove or disable components, restart your computer, press F8 to select Advanced Startup Options, and then select Safe Mode.
Technical Information:
*** STOP: 0x000000C2
Beginning dump of physical memory
Physical memory dump complete.

Contact your system administrator or technical support group for further
Sometimes error code may appear differently due to different cause of the error

Root Cause - Bad Pool Caller (stop code 0x000000C2)
  • A defective memory or a faulty hardware.
  • Generally this is associated with damaged or incompatible drivers.
  • If you encounter this message while upgrading Windows, it may mean that the hardware is not compatible with new updates.In that situation either rollback or  Try disconnecting devices, or looking for a suitable driver for Windows.
Solution 1 - Fix Driver issues
Restart your system and keep pressing f8 immediately to boot windows in safe mode.
  1. Login and enter password if needed
  2. Then in safe mode click start->run 
  3. Type devmgmt.msc and hit enter this will run device manager
  4. Expand all (+) if needed and see if you find any yellow exclamation marks.Any yellow exclamation marks will indicate corrupted or incompatible drivers.
  5. Remove or uninstall that driver and install a updated copy of the driver from the official website.
Some of the most common Driver download pages are - 
Video Drivers: NvidaATI, Intel
Chipset and CPU drivers - Intel ,AMD, Via

Solution 2 - Check Memory 
Both Windows7 and Vista includes memory test program when booting from the Windows DVD.
or Download Free memory test software from : http://www.memtest.org
Burn it to black CD or make a bootable USBstick.Once booted it will test your memory. One full past will catch most errors, but you can let it run longer.
I would run it first to see if it finds any problems with either stick. If it does take one out and test on each stick individually.If only one stick tests bad then it's very likely the problem, but if both test bad ,or neither, then it's likely something else.

Solution 3 - Re install Windows
New installation if windows will insure that all drivers and hardware compatible errors are gone and everything will be back to normal.Pleasee backup your date before formatting your windows.

Hope this will solve all your blue screen problems. If you have something to contribute please use comment system to add to this post. Thanks


  1. Organized content is the best way to display or post an article, thank you for making it easy to digest your post.

  2. I instal new instalation (recover) and after lookt in internet youtube video was problem: Stop... ox2... why.

  3. Reinstalling windows is NOT a 'solution'...it is a surrender. Even a 'repair install' (or in-place upgrade,) would be stretching it as a so-called 'solution.'
