BSOD Physical MemoryDump

Hello, I've recently started experiencing BSOD talking about memory dumping.
I was just browsing the internet and playing pokemon on an emulator when it crashed.
I've read about how to troubleshoot it but earlier after installing updates for the drivers it crashed again..

I'm running Windows 7 ultimate 32 bit

CPU: AMD Athlon II X2 245 2.91Ghz
Vid Card: Nvidia Geforce 9500 GT

Win 8 Release candidate 8400

Avast can be a contributing cause of BSOD'S . Please remove and replace with Microsoft Security Essentials AT LEAST TO TEST

Microsoft Security Essentials - Free Antivirus for Windows

The current thread is making a bad pool request.  Typically this is at a bad IRQL level or double freeing the same allocation, etc.
Arg1: 00000007, Attempt to free pool which was already freed
Arg2: 00001097, (reserved)
Arg3: 0074006f, Memory contents of the pool block
Arg4: 8997fb08, Address of the block of pool being deallocated

Debugging Details:

GetPointerFromAddress: unable to read from 82b6c718
Unable to read MiSystemVaType memory at 82b4c160

These are typically due to Drivers...
  • 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 203956
    • 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.
