    Try this:

    Launch System Configuration (msconfig)

    Services tab:
    Hide all Microsoft services
    Press the [Disable all] button

    Startup tab:
    Press the [Disable all] button
    Enable Click image for larger version only your Antivirus (AV) real time protection if one is in the list (some AV programs startup using a different mechanism, so you might not see an AV item on the Startup tab)

    Restart your machine and report the status.

    Fair question,

    These changes tell Windows not to load items at boot time. If a program needs a service, it loads it when needed. You can always reverse the operation and have the services and startup items load at boot.

    I run all my machines without the extra load (no items sitting in memory waiting to be used) - the same as I suggested for your machine.

    Your welcome, it sounds as though changing the System Configuration helped. The question remains, what caused the IRQL_NOT_LESS_OR_EQUAL ntoskrnl.exe+150aa0

    If you're adventurous, you can enable items one-by-one until the issue resurfaces, then you know what caused it and can fix it - it's often a driver needing the correct version.

    You have effectively moved the problem out of the way, if that's good enough for you ... it's good enough for me.

    The cause was Glarysoft Utilities, the GUBootStartup.sys driver was performing illegal operations. The driver has been removed.

    The driver was waiting for an object at IRQL 2 which is an illegal operation.
    Waiting for an object isn't allowed at IRQL 2 or above, primarily because doing so, requires a context switch to another thread (the current thread's quantum expired); this could leave the current thread in a loop. Not only this, but thread scheduling occurs at this IRQL, usually in the form of DPC routines, if objects are waiting, they hold up DPC routines and prevent any threads from being schedule, resulting in a lot of problems. As a result, waiting for objects at this IRQL is marked as an illegal operation, although driver developers should abide by this rule, apparently not...
