    Windows 8.1 huge Latency

    A friend gave me this computer and i've been having huge sound issues(crackle noise) when i am downloading something or even when playing games, when i searched the problem i downloaded LatencyMon to see what was the problem but i couldnt fix it, so here i am looking for help.

    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. Also one or more ISR 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.
    LatencyMon has been analyzing your system for 2:27:01 (h:mm:ss) on all processors.

    SYSTEM INFORMATION
    _________________________________________________________________________________________________________
    Computer name: JOO
    OS version: Windows 8.1 , 6.3, build: 9600 (x64)
    Hardware: N751JK, ASUSTeK COMPUTER INC.
    CPU: GenuineIntel Intel(R) Core(TM) i7-4710HQ CPU @ 2.50GHz
    Logical processors: 8
    Processor groups: 1
    RAM: 16266 MB total




    _________________________________________________________________________________________________________
    CPU SPEED
    _________________________________________________________________________________________________________
    Reported CPU speed: 2494 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.




    _________________________________________________________________________________________________________
    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 (s): 52951,481191
    Average measured interrupt to process latency (s): 10,672993


    Highest measured interrupt to DPC latency (s): 31812,025485
    Average measured interrupt to DPC latency (s): 3,714564




    _________________________________________________________________________________________________________
    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 (s): 25061,766239
    Driver with highest ISR routine execution time: ndis.sys - Network Driver Interface Specification (NDIS), Microsoft Corporation


    Highest reported total ISR routine time (%): 0,034546
    Driver with highest ISR total time: ndis.sys - Network Driver Interface Specification (NDIS), Microsoft Corporation


    Total time spent in ISRs (%) 0,066844


    ISR count (execution time <250 s): 2995486
    ISR count (execution time 250-500 s): 0
    ISR count (execution time 500-999 s): 2663
    ISR count (execution time 1000-1999 s): 152
    ISR count (execution time 2000-3999 s): 35
    ISR count (execution time >=4000 s): 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 (s): 31948,410986
    Driver with highest DPC routine execution time: ndis.sys - Network Driver Interface Specification (NDIS), Microsoft Corporation


    Highest reported total DPC routine time (%): 0,146136
    Driver with highest DPC total execution time: ndis.sys - Network Driver Interface Specification (NDIS), Microsoft Corporation


    Total time spent in DPCs (%) 0,258470


    DPC count (execution time <250 s): 23938381
    DPC count (execution time 250-500 s): 0
    DPC count (execution time 500-999 s): 86505
    DPC count (execution time 1000-1999 s): 7604
    DPC count (execution time 2000-3999 s): 2304
    DPC count (execution time >=4000 s): 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: svchost.exe


    Total number of hard pagefaults 13856
    Hard pagefault count of hardest hit process: 5872
    Number of processes hit: 27
