    Extremely High Latency

    Hi guys, I have been having this problem for the past 2 weeks or so. I have tried numerous re-formats, going back to Windows 8.1, disabling/enabling lots of devices, all to no avail. Basically I can't even use the computer anymore. Audio is a nightmare. I am suspecting a faulty motherboard or HDD (I don't have SSD). Check my Latency Monitor reports here:

    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. At least one detected problem appears to be network related. In case you are using a WLAN adapter, try disabling it to get better results. One problem may be related to power management, disable CPU throttling settings in Control Panel and BIOS setup. Check for BIOS updates.

    SYSTEM INFORMATION
    _________________________________________________________________________________________________________
    Computer name: DESKTOP-QJ8RC7A
    OS version: Windows 10 , 10.0, build: 10586 (x64)
    Hardware: Z270-Gaming K3, Gigabyte Technology Co., Ltd.
    CPU: GenuineIntel Intel(R) Core(TM) i7-7700 CPU @ 3.60GHz

    CPU SPEED
    _________________________________________________________________________________________________________
    Reported CPU speed: 360 MHz
    Measured CPU speed: 1 MHz (approx.)

    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 (Ás): 30934.444714
    Average measured interrupt to process latency (Ás): 13.921299

    Highest measured interrupt to DPC latency (Ás): 30931.315827
    Average measured interrupt to DPC latency (Ás): 11.731923


    _________________________________________________________________________________________________________
    REPORTED ISRs
    _________________________________________________________________________________________________________
    Interrupt service routines are routines installed by the OS and device drivers that execute in response to a hardware interrupt signal.

    Highest ISR routine execution time (Ás): 306.9150
    Driver with highest ISR routine execution time: dxgkrnl.sys - DirectX Graphics Kernel, Microsoft Corporation

    Highest reported total ISR routine time (%): 0.091659
    Driver with highest ISR total time: storport.sys - Microsoft Storage Port Driver, Microsoft Corporation

    Total time spent in ISRs (%) 0.142328

    ISR count (execution time <250 Ás): 5378763
    ISR count (execution time 250-500 Ás): 0
    ISR count (execution time 500-999 Ás): 3
    ISR count (execution time 1000-1999 Ás): 0
    ISR count (execution time 2000-3999 Ás): 0
    ISR count (execution time >=4000 Ás): 0


    _________________________________________________________________________________________________________
    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.

    Highest DPC routine execution time (Ás): 30950.207222
    Driver with highest DPC routine execution time: ndis.sys - Network Driver Interface Specification (NDIS), Microsoft Corporation

    Highest reported total DPC routine time (%): 0.183313
    Driver with highest DPC total execution time: ndis.sys - Network Driver Interface Specification (NDIS), Microsoft Corporation

    Total time spent in DPCs (%) 0.498760

    DPC count (execution time <250 Ás): 14471514
    DPC count (execution time 250-500 Ás): 0
    DPC count (execution time 500-999 Ás): 19158
    DPC count (execution time 1000-1999 Ás): 16669
    DPC count (execution time 2000-3999 Ás): 3051
    DPC count (execution time >=4000 Ás): 0


    _________________________________________________________________________________________________________
    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: leagueclient.exe

    Total number of hard pagefaults 59867
    Hard pagefault count of hardest hit process: 15536
    Highest hard pagefault resolution time (Ás): 2812413.218056
    Total time spent in hard pagefaults (%): 1.387964
    Number of processes hit: 50
