Blue Screen BCCODE 19 BAD POOL HEADER Windows 7 Error

Hi, well my problem is that I have a Toshiba laptop with Windows Vista (Home Premium 32-bit), and I upgraded it to Windows 7 (Home Premium 32-bit.).

 

The install was clean and with a new hard drive,but every time I'm using the laptop occasionally the ''Blue screen of dead'' appears.

So the error that appears says this:

 

BAD POOL HEADER

Blue screen

BCCODE19

Service Pack 1_0

Product_256_1

C:/windows/minidump/041212-4-24601-01.dmp

C:/users/Me/AppData/Local/Temp/wer-42931-0.sysdata.xml

 

Then I look into the Devices and Printers windows and there's and icon of my laptop with my laptop's name with the yellow triangle thing with the ''!'' sign.

And It says that the driver of unknown device is missing.

 

I tried the safemode, and the Last good known configuration methods but I don't know what to do next.

 

I really don't know what to do, I read in the forums that it may be a non-updated drivers issue, or a hardware problem occasionally the RAM, or that my laptop is not compatible with Windows 7 but I know that it is, and the problem of it might be the last system change but it dosen't tell me if is either a sofware or hardware issue.

Hi,

Did you update the BIOS, chipset drivers, and all the other drivers that might be available
at Toshiba Support?
Also check the maker of the Video device for updated drivers such as ATI,
Nvidia, or Intel, whoever made the video device.

Toshiba does have a lot of information on upgrading many of their models to Windows 7 and be
sure to check with Toshiba Support and ask in their forums for you model as others might have had
the same issues or there may be known issues with recommended appropriate corrective actions.

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 and post screen shot/picture.

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.

BCCode: 19    0x00000019

That could be drivers although antivirus/antispyware/security programs and other hardware
are also probable causes. Updating the major drivers and BIOS would be the best plan of
attack. If needed also try uninstalling your antivirus/security as a test.

If needed run Driver Verifier to try to determine the cause. (Good idea to update BIOS and
all the major drivers). For netio.sys it most often is the Network Drivers.

Use BlueScreenView to see if there is a driver specified in the error message. Also check with
MyEventViewer at the time of the BlueScreen.

If DriverVerifier creates a minidump upload it and post the link here so we can analyze it.

References to Vista also apply to Windows 7.

This is my generic how to for proper driver updates : (BIOS and major drivers) 

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.
http://pcsupport.about.com/od/driverssupport/ht/driverdlmfgr.htm

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.

Thank you very very much haha. I run a driver scanner to my laptop, and it came in the report that I needed to update 4 drivers, so I did.

But the Unknown device with the driver missing doesn't go away... what is that device?

 

thx

Hi,

Check in Control Panel - Device Manager to see if anything is listed that helps.

One possibility is the Card Reader driver. Check the driver updates available
from Toshiba direct. Forget using automatiic driver updating programs as they
will eventually fail sometimes with spectacular results (BAD).

Use DriverView to see what versions are installed and compare those to the
ones at Toshiba for your model. And remember some drivers are probably
not installed and need to be.

Also check for BIOS and chipset driver updates at Toshiba.

Hope this helps.

Hi,

 

Every driver that I look out in toshiba's drivers page, It's and old one, like from 2009.

 

I got 3 of the 4 direvers from other pages. But the unknown device is still there

 

https://skydrive.live.com/redir.aspx?cid=b2839e2e917cff0b&resid=B2839E2E917CFF0B!675&parid=root

 

there is images and the minidump folder that you ask for.

 

Thank you very much for your help.

Hi,

Did you look in Control Panel - Device Manager?

The latest drivers at Toshiba in most cases will be newer than the ones installed
during the Upgrade though that is not a sure thing. So use DriverView as indicated
in the troubleshooter above to actually compare the versions and not just the dates.
Some driver updates will be available at the OEM device maker such as Video,
Sound/Audio, NIC (wired) and WiFi (wireless), touchpad and others.

Good chance the missing device is a driver not installed, such as the Memory Card
reader (again check Device Manager).

Read and follow the methods very closely instead of looking for alternative shortcut
methods which will not work.

Hope this helps.

Hi,

The drivers in toshiba web page are older both versions and dates.

Why do I open the device manager? It only shows me the unknown device and the missing driver.

I add the files to my skydrive:

 

https://skydrive.live.com/redir.aspx?cid=b2839e2e917cff0b&resid=B2839E2E917CFF0B!675&parid=root

 

Would you analyze it? Thank you, if I get more info about the problem I will post it.

Hi,

I looked at the picture and it does not tell me anything.

In Device Manager - double click the device - Driver tab - try Update Driver.

If no help then Right Click the device - UNINSTALL - when complete reboot
and see if that helps.

Did you look at Toshiba for drivers that are NOT loaded on your system?
 
I mentioned the Card Reader above, did you check it? Does the card reader
work? Are there any devices that do not work?

You are still trying to find shortcuts instead of doing what is needed to resolve the
issue.

Check with Toshiba Support and their forums.

Hope this helps.

Hi,

I updated the card reader and all of the drivers that I could found before anything.

Yes there are some softwares on the toshiba page that I don't have installed.

 

I did the update driver of the ''Unkown Device'', but it didn't work, so I uninstalled it.

The yellow thing now doesn't appear in the devices and printers window.

And it doesn't appear in the device manager anymore.

All of the devices work properly.

The only thing that I didn't get the driver to updated it is the Atheros AR5007EG Wireless Network Addapter.

And in the taskbar says it is disabled, but windows says that the driver is up to date.

Even tho the wireless internet works properly right now.

If the bsod doesn't appear in the next days, does it means that the problem is solved?

Im going to install the thing that I don't have in the Toshiba's page tho.

 

Thanks for all of your time and help.

Hi, the driver that I downloaded for this adapter is a .rar file with .sys, .cat and .inf files.

What do I do with them?

 

PS.

If the bsod doesn't appear in the next days, with the unknown device uninstalled, does it means that the problem is solved?

 

Thank you.
