Driver_irql_not_less_or_equal Stop 0x000000d1

  1. Hi. This is my first post. My computer is crashing with the referenced BSOD. I know many others have had this problem and from reading the Forum there apparently are many possible causes. The full STOP line is:

    STOP 0x000000D1 (0x71A5DF52, 0x00000002, 0x00000008, 0x71A5DF32)

    I am running Windows Media Center SP2 on an HP m7580n. I haven't installed any new hardware or software drivers. I have run both anti-virus and anti-spyware programs and the results have been clean. The problem occurs only about once a day. There doesn't appear to be any particular triggering event. Because of that, an uneducated guess would suggest a possible power supply or memory problem. But, I could be totally off base.

    After the crash, there is no problem rebooting.

    Minidumps attached. I have no experience reading minidumps. Any help in diagnosing the problem would be greatly appreciated.

    Outpost Firewall is the problem. Your version is dated 2002. See HERE for the same problem.

    BugCheck 100000D1, {71a5df52, 2, 8, 71a5df52}
    PROCESS_NAME: svchost.exe
    Probably caused by : Unknown_Image ( INVALID_CONTEXT )

    Thank you very much. Obviously I'll have to replace my firewall.
