Storeport.sys has the highest DPC routine 100781, any fixes? RRS feed

  • Question

  • I Just got and i5-7500 and before i put it in i noticed my pc was lagging a lot.
    Something is up and i dont know what, i updated the nvme, gpu audio and usb drives bit it didnt work.
    Reverting to an older systemimage didn't help either, noir reflashing the bios.
    All games lagg and HL Alys crashed now and it didnt do that before.

    Here is the LatencyMon Report

    CONCLUSION
    _________________________________________________________________________________________________________
    Your system appears to be having trouble handling real-time audio and other tasks. You are likely to experience buffer underruns appearing as drop outs, clicks or pops. One or more DPC routines that belong to a driver running in your system appear to be executing for too long. One problem may be related to power management, disable CPU throttling settings in Control Panel and BIOS setup. Check for BIOS updates.

    CPU SPEED
    _________________________________________________________________________________________________________
    Reported CPU speed:                                   3696 MHz

    Note: reported execution times may be calculated based on a fixed reported CPU speed. Disable variable speed settings like Intel Speed Step and AMD Cool N Quiet in the BIOS setup for more accurate results.

    WARNING: the CPU speed that was measured is only a fraction of the CPU speed reported. Your CPUs may be throttled back due to variable speed settings and thermal issues. It is suggested that you run a utility which reports your actual CPU frequency and temperature.

    MEASURED INTERRUPT TO USER PROCESS LATENCIES
    _________________________________________________________________________________________________________
    The interrupt to process latency reflects the measured interval that a usermode process needed to respond to a hardware request from the moment the interrupt service routine started execution. This includes the scheduling and execution of a DPC routine, the signaling of an event and the waking up of a usermode thread from an idle wait state in response to that event.

    Highest measured interrupt to process latency (µs):   31535.20
    Average measured interrupt to process latency (µs):   6.724318

    Highest measured interrupt to DPC latency (µs):       31532.20
    Average measured interrupt to DPC latency (µs):       3.046365

    REPORTED DPCs
    _________________________________________________________________________________________________________
    DPC routines are part of the interrupt servicing dispatch mechanism and disable the possibility for a process to utilize the CPU while it is interrupted until the DPC has finished execution.

    Driver with highest DPC routine execution time:       storport.sys - Microsoft Storage Port Driver, Microsoft Corporation

     REPORTED HARD PAGEFAULTS
    _________________________________________________________________________________________________________
    Hard pagefaults are events that get triggered by making use of virtual memory that is not resident in RAM but backed by a memory mapped file on disk. The process of resolving the hard pagefault requires reading in the memory from disk while the process is interrupted and blocked from execution.

    NOTE: some processes were hit by hard pagefaults. If these were programs producing audio, they are likely to interrupt the audio stream resulting in dropouts, clicks and pops. Check the Processes tab to see which programs were hit.

    Process with highest pagefault count:                 avgsvc.exe

    Total number of hard pagefaults                       1271
    Hard pagefault count of hardest hit process:          1261
    Number of processes hit:                              9
