    Solutions I've already tried:

    Uninstalling Microsoft ACPI-Complaint Control Method Battery

    Formatting

    Uninstalling Network Drivers

    Uninstalling Audio Drivers

    Using the Registry Editor

    Factory Resetting

    Windows Update


    If anyone has a specific solution, please help!

    :)

    High DPC latency causing audio stutters

    Quite different hardware but this may have your attention.

    Sound artifacts and high DPC latency seemingly related to storport driver can be caused by switching between Cx power saving processor states. My pci-express add-on soundcard works correctly only if C states greater than C1 are disabled:

    If you want to give it a try, see your mobo manual:

    High DPC latency causing audio stutters

    Does Latency Mon show hard page faults (and what device)?
    That seems to be the biggest item.
    Run Latency Mon and the post the overall screen (mine is shown below).
