Windows 7 is shutting down. Blue Screen - BAD_POOL_CALLER

Hi,

References to Vista also apply to Windows 7.

This is my generic how to for proper driver updates : (Check for BIOS and driver updates.)

This utility makes it easy to see which versions are loaded :

DriverView - Free - utility displays the list of all device drivers currently loaded on your system.

For each driver in the list, additional useful information is displayed: load address of the driver,

description, version, product name, company that created the driver, and more.

http://www.nirsoft.net/utils/driverview.html

For Drivers check System Maker as fallbacks and Device Maker's which are the most current.

Control Panel - Device Manager - Display Adapter - write down the make and complete model

of your video adapter - double click - Driver's tab - write down the version info. Now click UPdate

Driver (this may not do anything as MS is far behind certifying drivers) - then Right Click -

Uninstall - REBOOT this will refresh the driver stack.

Repeat that for Network - Network Card (NIC), Wifi, Sound, Mouse and Keyboard if 3rd party

with their own software and drivers and any other major device drivers you have.

Now go to System Maker's site (Dell, HP, Toshiba as examples) (as rollback) and then Device

Maker's site (Realtek, Intel, Nvidia, ATI as examples) and get their latest versions. (Look for

BIOS, Chipset and software updates at System Maker's site while there.)

Download - SAVE - go to where you put them - Right Click - RUN AD ADMIN - REBOOT after

each installation.

Always check in Device Manager - Drivers tab to be sure the version you are installing actually

shows up. This is because some drivers rollback before the latest is installed (sound drivers

particularly do this) so install a driver - reboot - check to be sure it is installed and repeat as

needed.

Repeat at Device Makers - BTW at Device Makers DO NOT RUN THEIR SCANNER - check

manually by model.

Manually look at manufacturer's sites for drivers - and Device Maker's sites.

Installing and updating drivers in Windows 7 (updating drivers manually using the methods above

is preferred to ensure the latest drivers from System maker and Device makers are found)

http://www.sevenforums.com/tutorials/43216-installing-updating-drivers-7-a.html

If you update drivers manually then it is a good idea to disable Driver Installations in Windows

Updates, this leaves Windows Updates ON however it will not install drivers which will usually be

older and cause issues. If Updates suggests a new driver then HIDE it (Right Click on it) and then

go look for new ones manually if you wish.

==========================================

Memory tests do not catch all errors such as mismatched memory (possible even for sticks

that appear to be identical) and when faster memory is placed in system behind slower memory.

So it is best to also swap sticks in and out to check for those even if all memory tests fail to show

a problem.

To test RAM check here - let it run 4+ hours or so.   <-- best methodwww.memtest.org

Hi,

Resolving stop (blue screen) errors in Windows 7 - has a section for if you can or can't start Windows.http://windows.microsoft.com/en-us/windows7/Resolving-stop-blue-screen-errors-in-Windows-7 

See this thread for information on using BlueScreenView, MyEventViewer, and other methods to

troubleshoot BlueScreens - top 3 answers (+1 other).

http://answers.microsoft.com/en-us/windows/forum/windows_7-system/sometimes-i-get-a-blue-screen-when-using-ie-8/c675b7b8-795f-474d-a1c4-6b77b3fcd990 

We can analyze the minidumps if you make them available from the SkyDrive or other file

sharing sites (such as MediaFire). If you have problems uploading the minidumps copy

them to the Desktop or the Documents folder and upload them from there.

Zip or upload the contents of C:\Windows\minidump

Use SkyDrive to upload collected files.

BCCode: C2   0x000000C2This error is usually a driver issue and display adapter (video) driver is the most suspect though it

could be others. Antivirus/antispyware/security programs, hardware (heat) and major software issues

can also cause the error. When you get to the driver section of the troubleshooter use my generic

methods in the next message and then return to the troubleshooter if needed. Memory issues are

another possibility after drivers.

Have you added hardware recently or updated drivers? Be sure to look in Control Panel - Windows

Updates to see if any drivers were updated there. Other lessor possibilities include antivirus/anti-

spyware/security programs.

BCCode: C2   0x000000C2 Bug Check 0xC2: BAD_POOL_CALLERThe BAD_POOL_CALLER bug check has a value of 0x000000C2. This indicates that the current thread is making a bad pool request.

Important Info If You Have Received a STOP Code

If you received a blue screen error, or stop code, the computer has shut down abruptly to protect itself from data loss. A hardware device, its driver, or related software might have caused this error. If your copy of Windows came with your computer, call the manufacturer of your computer. If you purchased Windows separately from your computer, Microsoft provides support. To find contact info for Microsoft or your computer manufacturer, Contact Support.

If you have experience with computers and want to try to recover from this error, follow the steps provided in the Microsoft article Resolving STOP (Blue Screen) Errors in Windows.

These actions might prevent an error like this from happening again:

1. Download and install updates and device drivers for your computer from Windows Update.
2. Scan your computer for computer viruses.
3. Check your hard disk for errors.

You can disable Driver Verifier

http://support.microsoft.com/kb/244617

Start - type in Search box -> verifier /reset      hit enter to disable

Use BlueScreenView to see if there is a driver specified in the error message. Also

check with MyEventViewer at the time of the BlueScreen. (See the troubleshooter

above.)

Upload any minidumps created when you run DriverVerifier so we can analyze them.

=========================================================

=========================================================

Look in the Event Viewer to see if anything is reported about those.

Also do this so you can see the likely bluescreens.

Windows Vista automatically restarts if your PC encounters an error that causes it to crash.

(also Windows 7)

Here are some methods to possibly fix the blue screen issue. If you could give the Blue Screen info

that would help. Such as the BCC and the other 4 entries on the lower left. And any other error

information such as STOP codes and info such as IRQL_NOT_LESS_OR_EQUAL or PAGE_FAULT_IN_NONPAGED_AREA and similar messages.

As examples :

BCCode: 116

BCP1: 87BC9510

BCP2: 8C013D80

BCP3: 00000000

BCP4: 00000002

or in this format :

Stop: 0x00000000 (oxoooooooo oxoooooooo oxooooooooo oxoooooooo)

tcpip.sys - Address 0x00000000 base at 0x000000000 DateStamp 0x000000000

This is an excellent tool for posting Blue Screen Error InformationBlueScreenView scans all your minidump files created during 'blue screen of death'crashes, and displays the information about all crashes in one table - Freehttp://www.nirsoft.net/utils/blue\_screen\_view.html

Many BlueScreens are caused by old or corrupted drivers, especially video drivers however

there are other causes.

You can do these in Safe Mode if needed or from Command Prompt from Vista DVD or

Recovery Options if your system has that installed by the maker.
