    BSOD anytime, doing anything (including idle)


    I've been getting BSOD's for the past month or so now, and it's slowly getting worse. A friend of mine has helped me eliminate software issues (killdisk, then reinstall windows). The stated cause on the BSOD range from 'Iirql_not_less_or_equal' to 'bad_pool_header' to 'memory_management' and more besides. Attached is the Dm log .zip file. Thanks

    *** WARNING: Unable to verify timestamp for aswSnx.sys

    Uninstall Avast using Avast Uninstall Utility. Use Microsoft Security Essentials as your antivirus with windows inbuilt firewall, and free MBAM as the on demand scanner.

    Let us know for any further BSOD.

    Will do. Just a point to note, before the computer was wiped, I wasn't using Avast. My computer showed BSOD's less than 24 hours after the killdisk (only windows, headset and speaker drivers, DOTA 2 and Avast along with driver updates had been installed)

    The new crash dump says nothing other than it is somehow memory related. It may be the physical RAM, it may be any driver passing bad info to the memory. Let us check both the possibilities.

    Test your RAM modules for possible errors. Run memtest86+ for at least 8 consecutive passes.

    If it start showing errors/red lines, stop testing. A single error is enough to determine that something is going bad there.

    If it does not show any error, enable Driver Verifier to monitor the drivers. Run Driver Verifier for 24 hours or the occurrence of the next crash, whichever is earlier.

       Information
    Why Driver Verifier:
    It puts a stress on the drivers, ans so it makes the unstable drivers crash. Hopefully the driver that crashes is recorded in the memory dump.

    How Can we know that DV is enabled:
    It will make the system bit of slow, laggy.

       Warning
    Before enabling DV, make it sure that you have earlier System restore points made in your computer. You can check it easily by using CCleaner looking at Tools > System Restore.

    If there is no points, make a System Restore Point manually before enabling DV.

       Tip



    Let us know the results, with the subsequent crash dumps, if any.

    Adding my dm log file, unsure if I need to at this point (but have done to be sure)....
    I ran the memtest and within 1-2 minutes, my screen was filled with reams of red. Not sure what to do next, hoping you guys can help.

    Now follow the "Part 3: If You Have Errors:" of How to Test and Diagnose RAM Issues with Memtest86+

    Errors/red lines means one or more RAM is faulty. But the fault may occur due to a faulty DIMM slot, too, which is a motherboard component. Using memtest86+, you can discriminate between a faulty RAM and a faulty motherboard.

    How? Say you have two RAM sticks and two DIMM slots. You obtained errors at the test with all RAM sticks installed. Now, remove all the sticks but one. Test it in all the available slots, one by one. Continue the same procedure for all the available sticks.
    How to make the inference that is it a RAM issue or it is a motherboard issue? Suppose you have got the result like that:
    No code has to be inserted here.
    It is a RAM, a bad RAM.

    But if you have got a result like that:
    No code has to be inserted here.
    It is a motherboard issue. The particular slot is bad.

    If it is a bad RAM, you need to change the RAM. Take the other existing (good) RAM to the shop and get one of the exactly same specification. The best is, get a totally new RAM KIT.

    If it is a bad slot, it is a motherboard issue. But changing the motherboard needs a preparation for most of us; so dont populate that slot for the time being.

    No bugcheck analysis is needed until the RAM issue is fixed.
