    Intermittent BSOD's PFN and Driver IRQL


    Hello All,

    I am having some issues with my Machine. My game graphics will mess up upon occasion and shut me out of games(Global Agenda, Tribes Ascension) all together. Intermittent BSOD's PFN List Corrupt and Driver IRQL not Less or Equal.

    I run a retail installed version of Windows 7 Professional 64bit. This is a machine I have built a couple of years ago. The OS install is more recent.

    I have run memtest86 and I have passed with no errors through more than 7 tests.

    I have updated my graphics card driver to the newest version.

    I believe it to be a driver issue but I cannot pinpoint the outdated driver that may cause this. I did run driver verifier which resulted in consistent blue screens. I had to do a system restore in order to login without Safe Mode.

    Attached is my dump files and performance report.

    Please let me know what I might do to fix this and thanks for your time!

    Anti Virus


    I had Avast during these scans and performance reports. I have since moved to Microsoft Security Essentials. Just an update for anyone looking to assist.

    Several of your crashes (driver verified) were Related to dtsoftbus01.sys Virtual Bus Driver from DT Soft Ltd. Please remove it at least to test.

    Please remove any CD visualization programs such as Daemon Tools and Alcohol 120%.

    They use a driver, found in your dmp, called sptd.sys, that is notorious for causing BSODs.

    Use this SPTD uninstaller DuplexSecure - Downloads DuplexSecure - FAQ

    when you're done you can use this Freeware:

    MagicISO Virtual CD/DVD-ROM (MagicDisc) in its place

    Using MagicISO to create ISO image files

    Your DMP's indicate that remnants of Avast remain.
    Did you use their uninstall tool?

    JMH,

    I have already removed this program. I will place updated dump files if I can recreate the BSOD


    zigzag3143,

    Should I utilize the Driver verifier now that I have removed Daemon tools for troubleshooting?

    Thanks for your responses!

    If you have stopped crashing there is no need to run verifier, so I would wait a bit.
