Help Reading Minidump

  1. At random times (sometimes at startup, sometimes after 30 minutes or more) a BSOD appears displaying one of these messages: multiple irp complete requests, pfn list corrupt, or driver irql not less or equal. These errors don't occur every time I run my computer, but maybe once in 5 startups and sometimes popping up when I restart my modem.

    I ran Driver Magician and Driver Detective and made sure all my drivers were updated. I also ran Vista's built-in memory diagnostic tool and memtest86+ (for 3 passes) but both came up with no errors. I couldn't find any consistent errors in Event Viewer and there were no warnings in Device Manager.

    I tried using WinDbg to read my minidump files, but I get errors like "Your debugger is not using the correct symbols" and "Symbols can not be loaded because symbol path is not initialized."

    So can someone please help me interpret the minidumps (I've attached 6 of the most recent)? Thanks in advance!

    P.S. I've also attached some of the Windows error logs I get when I restart after the BSOD. When I press "check for solution", sometimes Windows says an outdated version of Kaspersky is the culprit. Yet I have the latest version (, so I don't know...

    You should only have one AV program installed. Remove one and then post any new minidumps received.

    Hm...I've always had both Kaspersky and Avast installed and received no problems. I'll uninstall Avast and see if that fixed anything. Thanks!

    So it happened again, when I booted up and logged in. "Multiple irp complete requests". I've uploaded the minidump and the Windows error notification.

    Window's "check for solution" option told me "the problem was caused by antivirus software" but couldn't determine the "specific cause". Kaspersky is updated and Avast is uninstalled. What could be the error?

    Inside the 1 MiniDump:
    Your Trillian Chat Client, plus Vista, plus Kaspersky caused a fault.

    I think you chose the wrong AntiVirus to un-install
    Kaspersky is just too big (memory wise) these days I feel

    Thanks for the help! Do you think uninstalling just Trillian would resolve this error? I'm pretty satisfied with Kaspersky (but not Trillian).

    Sadly the fault points to Kaspersky
    But it's a matter of trial and error

    ie it could work, just removing Trillian

    Okay, I installed the newest version of Kaspersky ( and haven't gotten a problem in three days. Yet the BSOD just popped up again...

    Is it still Kaspersky's fault?

    States it can be driver issue
    Please update all your drivers from your manufactures support page.
