    Is there anyway for me to reinstall a fresh windows copy and easily get it back to the state that its currently in?

    There are different third party software vendors that make imaging software.
    If you can only save files and install a new version of Windows you reduce problems with the return of questionable drivers.
    Macrium is frequently used on Ten Forums and it has been used most often to rescue failed boots.
    Macrium creates an image of the drive and when you repair using the image you unfortunately lose applications.
    So there is no full proof method to get everything restored as it once was.
    There are different versions of Macrium: Macrium Software | Your image is everything
    Macrium Reflect KnowledgeBase - KnowledgeBase v7 - Macrium Reflect Knowledgebase - KnowledgeBase v7 - Macrium Reflect Knowledgebase

    When considering time and the trade offs: continue troubleshooting with unknown drivers and malware history versus clean install then testing you may find one of the choices to more efficient and effective.
    Please post information about the ESET malware.

    Imaging software, like Macrium Reflect, take all data from selected partitions and make an image of it. If this image is restored you restore everything that was on selected partitions. This includes applications.

    Im confused, as zbook says that I would lose my applications, and axe0 says that I will retain them?

    naseemessa, I'm saying you will retain them when you backup the entire partition. Zbook is saying that one can't backup programs solely without anything else.

    The only way to get back to the state you're currently in, without problems, is by performing a clean install and manually restore personal files & reinstall programs.

    Hi. I reinstalled Windows using the option to keep my personal files, yet LatencyMon still picks up latency.

    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 0:04:58 (h:mm:ss) on all processors.

    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): 5122.467843
    Average measured interrupt to process latency (s): 6.650679

    Highest measured interrupt to DPC latency (s): 5108.519108
    Average measured interrupt to DPC latency (s): 2.469288


    ____________________________________________________________________________________________________ _____
    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): 2120.967147
    Driver with highest ISR routine execution time: Wdf01000.sys - Kernel Mode Driver Framework Runtime, Microsoft Corporation

    Highest reported total ISR routine time (%): 0.005256
    Driver with highest ISR total time: Wdf01000.sys - Kernel Mode Driver Framework Runtime, Microsoft Corporation

    Total time spent in ISRs (%) 0.006214

    ISR count (execution time <250 s): 14264
    ISR count (execution time 250-500 s): 0

    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): 2569.334936
    Driver with highest DPC routine execution time: tcpip.sys - TCP/IP Driver, Microsoft Corporation

    Highest reported total DPC routine time (%): 0.040210

    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.


    Process with highest pagefault count: none

    Total number of hard pagefaults 0
    Hard pagefault count of hardest hit process: 0
    Highest hard pagefault resolution time (s): 0.0
    Total time spent in hard pagefaults (%): 0.0

    Okay, I reset Windows completely, wiping my personal files on C Drive, and ran LatencyMon again. Here are more results

    I am seriously confused, what could the issue be?

    As some additional findings, I have noticed that when the dialog box sound plays, I can hear a popping sound from the speakers presumably, and speedtest.net results have showed that Im only getting 50% of my line speed on my laptop. I have tested the internet speed on other devices, and they get the full speed, its only the laptop thats a problem.
