BSOD while watching youtube videos! BAD POOL HEADER x19

Hello my week old custom built gaming pc crashed about a hour ago with these BSOD codes. Ive updated most drivers except for my tp link usb wireless card so ill do that now. Thanks in advance to those who help!:) I was using google chrome.

I tried updating the wireless card but windows7 is weird handling the drives it wouldnt let me update the drivers manually and if i try and let it auto update it installs a driver from 2010.

UPDATE: Ive ran blue screen viewer and it shows that a ntoskrnl.exe is causing the crash.

Many of us on the forums actually do not recommend automated optimization tools for Windows 7. Windows 7 does a much better job of handling its own optimization than its predecessors did. We especially do not recommend registry cleaning as an "optimization" step because automated registry cleaning causes more harm to the registry than it actually repairs.

In the future, if you need help optimizing Windows 7, please post a thread in Performance & Maintenance - Windows 7 Forums or follow the tutorial enclosed in that forum to Optimize Windows 7.

Your crashes may be related to an underlying driver or to audiodg.exe.
  • An underlying driver may be incompatible\conflicting with your system. Run Driver Verifier to find any issues. To run Driver Verifier, do the following:
    a. Backup your system and user files
    b. Create a system restore point
    c. If you do not have a Windows 7 DVD, Create a system repair disc
    d. In Windows 7:
    • Click the Start Menu
    • Type verifier in Search programs and files (do not hit enter)
    • Right click verifier and click Run as administrator
    • Put a tick in Create custom settings (for code developers) and click next
    • Put a tick in Select individual settings from a full list and click next
    • Set up the individual settings as in the image and click next
      Attachment 209758
    • Put a tick in Select driver names from a list
    • Put a tick next to all non-Microsoft drivers.
    • Click Finish.
    • Restart your computer.

    If Windows cannot start in normal mode with driver verifier running, start in safe mode. If it cannot start in safe mode or normal mode, restore the system restore point using System Restore OPTION TWO.

    Thanks to zigzag3143 for contributing to the Verifier steps.
    If you are unable to start Windows with all drivers being verified or if the blue screen crashes fail to create .dmp files, run them in groups of 5 or 10 until you find a group that causes blue screen crashes and stores the blue screen .dmp files.
    The idea with Verifier is to cause the system to crash, so do the things you normally do that cause crashes. After you have a few crashes, upload the crash reports for us to take a look and try to find patterns.

    When you are ready to disable Verifier: Start Menu -> All Programs -> Accessories -> Right click Command Prompt -> Run as administrator -> Type the following command and then Enter:
    verifier /reset
    -> Restart your computer.

  • See Fix: Audiodg.exe High CPU Usage for the possible audiodg.exe issue.

Some wireless drivers for some reason cause problems in Windows. When you install them to overwrite the current drivers via the install package that vendors provide, they don't stick. I do not know why. Also, if a user tries to update them through device manager, for some reason, Windows informs the user that the system already has the most up to date drivers. Again, I do not know why. There is a special procedure that must be followed for these devices to update them properly.

Now that you have downloaded the latest wireless drivers package, here are the steps to install it so it sticks and actually updates the drivers for the device.
  1. Click Start Menu
  2. Right Click My Computer/Computer
  3. Click Manage
  4. Click Device Manager from the list on the left
  5. Expand Network adapters
  6. Right click the wireless network device
  7. Click Uninstall (do not click OK in the dialog box that pops up after hitting Uninstall)
  8. Put a tick in Delete driver software for this device and hit OK
  9. Do not restart your computer
  10. Install the downloaded driver for the wireless network device.

  1. Login as an adminstrative user.
  2. Click Start Menu
  3. Click Control Panel
  4. Click Hardware and Sound
  5. Click Device Manager (the last link under Devices and Printers)
  6. Expand Network adapters
  7. Right click the wireless network device
  8. Click Uninstall (do not click OK in the dialog box that pops up after hitting Uninstall)
  9. Put a tick in Delete driver software for this device and hit OK
  10. Do not restart your computer
  11. Install the downloaded driver for the wireless network device.

You're welcome. There were no Verifier enabled crashes in the last batch, so hopefully the next batch will give some clues.
