    IRQL Not Less Or Equal crash, win32k.sys

    I have a sony vaio laptiop with Windows Vista Home Premium with 4 gigs of
    RAM. I have been frequently getting blue screen crashes right after start-up
    and shut-down.

    The complete dump file for the error is the following:


    ------------------------------------------------------------------
    IRQL_NOT_LESS_OR_EQUAL (a)
    An attempt was made to access a pageable (or completely invalid) address at an
    interrupt request level (IRQL) that is too high. This is usually
    caused by drivers using improper addresses.
    If a kernel debugger is available get the stack backtrace.
    Arguments:
    Arg1: 00000000, memory referenced
    Arg2: 0000001b, IRQL
    Arg3: 00000000, bitfield :
    bit 0 : value 0 = read operation, 1 = write operation
    bit 3 : value 0 = not an execute operation, 1 = execute operation (only on
    chips which support this level of status)
    Arg4: 82100cba, address which referenced memory

    Re: IRQL Not Less Or Equal crash, win32k.sys

    Hi,

    Something in Task Scheduler is trying to run and falling over, or something
    is trying to load TS and it's crashing. The memory address being accessed is
    invalid (arg 1), and the hardware is using a virtual IRQ, number 27 (arg 2).
    Two approaches to this might help diagnose the problem:

    1) Check TS for tasks trying to run at startup and shutdown. Check event
    viewer as well for mention of what's falling over.

    2) Run msinfo32 from the start/search line and go to hardware resources/IRQ
    and see if there is a device using #27. If so, see if there is an updated
    driver for that device from the manufacturer.

    Hello,

    For starters, thank you for trying to help. I do however have some questions
    regarding the solution you provided.

    1) The task scheduler have like dozens of tasks that are triggered by
    'start-up' or 'user log on', most of them are windows tasks. Should I look
    for any in particular?

    2) The event viewer also has millions of events stored. What exactly should
    I look for?

    3) I did look in msinfo32 but there are no devices using IRQ #27.

    Hi,

    1) Selectively begin disabling them until the problem stops.

    2) Under Windows Logs, check the System and Application logs at the time of
    the startup errors.

    3) Not surprised, as it may be that the issue could be that it is trying to
    invoke an IRQ that's not allocated.
