    Hi... i have re-formatted this PC and still cant get rid of the blue screen... i have a attached the mini dumps for perusal...

    I see the errors include 3 (no less...) types,
    BAD_POOL_HEADER
    IRQL_NOT_LESS_OR_EQUAL
    PAGE_FAULT_IN_NONPAGED_AREA

    I have done tests on both ram and HDD for error however none found... in fact had the hardware checked out and all is OK! I was told it is a software issue.

    Pls help me. Rgds.

    Hey there, welcome.

    1) Uninstall AVG with the removal tool in safe mode:

    http://windows7forums.com/blue-screen-death-bsod/50402-removal-tools-antivirus-software-drivers.html

    Then reboot and install MSE.

    2) Update your Atheros wireless driver. This is way too old for Windows 7:

    ar5211 ar5211.sys Fri Oct 26 05:20:34 2007

    Check the device manager for which type it is then download here and install:

    http://www.atheros.cz/

    3) Use the Avira! removal tool in safe mode from the link in step 1 above to remove Avira! and all it's remnants.

    Yes, my instructions are always very thorough and I include all pertinent information in my original post, leaving nothing out.

    The only way to know if the machine doesn't bsod any longer is to use it and see if it bsods any longer.

    If any new crashes happen, please post the new dumps. I'd image not if you follow well, so good luck and enjoy.

    incorrect... i did 2 above, if you recall the 5 message above. is it still the wrong version of the driver? if so, any idea where else i can look... cos the atheros link above doesnt have them.
    As for 3, i dont have a better option and dont prefer MSE to be honest. I WILL do 3 above and see... thanks again.

    An excerpt of your latest crash dump:

    Code:
    0: kd> lmvm ar5211
    start    end        module name
    8f4fb000 8f581140   ar5211     (deferred)             
        Image path: \SystemRoot\system32\DRIVERS\ar5211.sys
        Image name: ar5211.sys
        Timestamp:        Fri Oct 26 05:20:34 2007 (4721B162)
        CheckSum:         00090099
        ImageSize:        00086140
        Translations:     0000.04b0 0000.04e4 0409.04b0 0409.04e4
    
    Download the driver again. Extract it to a folder. Open device manager. Right click the wireless adapter. Choose Update Driver Software. Browse My Computer. Let me pick. Have disk. Browse.

    Now navigate to the extracted folder and double click on the .inf.

    Hit ok then next and it will install.

    --------

    I highly recommend MSE as it is the only antivirus of them all that never crashes machines under any circumstances.

    Also I will note, it is is Microsoft's best interest to keep the machine malware-free, while all others do not have an equal incentive.

    AR8132 is your ethernet adapter. We need to update the wireless.

    There should be another entry in the Network Adapter section of the device manager.

    What does it say? And are you sure that you have an actual wireless adapter installed?

    I believe it is solved...

    Hi TG,
    i removed avira and uninstalled the driver... that is the short of it.

    it crashed a few times as I was busy doing above.... but the crashed all happened as i was busy with the latter... this to me then signifies that the driver was the issue. However i followed your (great... by the way) instructions regarding the driver update and it eventually registered the updated driver.

    So far so good... i hope i wont be hassling you again with this problem.

    FOR ALL THOSE READING... THIS GUY KNOW'S HIS SH1T!!

    Thanks Again.

    Please follow the above quote. You are definitely without doubt now, having errors with your old wireless adapter driver. Here is the conclusive proof, and it has not been updated yet:

    Actually, also type this command in a command prompt, press enter then make a screen shot or 2 for everything, and attach:

    ipconfig /all

    Forget all of that. There is no driver available to you that will not cause crashes. Disconnect or remove the wireless adapter from your machine. Uninstall the Atheros wireless software and make sure to manually delete C:\Windows\System32\drivers\ar5211.sys if it is still there. Reboot and now you will not have any further crashes.

    Purchase a new wireless adapter and install.
