    Random audio stuttering and mouse freezing


    Hi, my computer will always randomly freeze for 1-3 seconds when I do normal tasks (like using chrome and skype). The freezes cause audio and mouse to also freeze during that time.

    I tried to swap CPUs, get a new mobo, use different RAM and nothing works. I've got this problem since Windows 8. But its been progressively worse. Now I also sometimes have problems POSTing and the display will turn black when I boot up to the login screen.

    I used latencymon to check which drivers are causing the problem and when I disable my GPU drivers the stuttering is gone. I don't have any of these problems when using DirectX apps. My GTX 660 has the latest drivers installed.

    I posted some more info into this issue with LatencyMon. It looks like it has something to do with dxgkrnl.sys and Wdf01000.sys. They both have the highest DPC and ISR counts. Not sure what to do cause i cant reinstall DirectX.

    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. 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  0:07:29  (h:mm:ss) on all processors.

    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.

     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.

    Can anyone help me out?

    I just done a clean install of my Nvidia gpu drivers and also reinserted the gpu into the slot. The issue still appears.

    Then it's not the Nvidia card, or drivers. It's either the chipset drivers, RAM, CPU, BIOS, mouse drivers, or audio drivers. OR, OR it'ss the fact that the Nvidia drivers are not compatible with Win 10/win8 or are not optimized for specific hardware, or something is bottle necking your system. If you have a 660, that specific card is old, so that too could be an issue where it doesn't go well with the latest drivers due to it being an older card

    The stuttering sound is probably only a byproduct of whatever is causing the mouse problem. I would eliminate the sound as a problem and focus on what is causing the intermittent mouse no response.

    Dig deeper into the Latency Mon report and see if you can find anything Latency Mon overwhelms (most) with data so it may take some time to digest it all.

    I don't get any problems with the gpu bottlenecking in any games. All these problems only happen when I'm not in a game. I've already updated most of my drivers. I will be updating my audio driver again.

    I also tested with another GPU (AMD HD 7870) and I had no more boot problems or stuttering.

    The only things i can find that seems to be causing all the problems is this. These are the only ones that have very high DPC and ISR count. What should I do?

    "High Definition Audio" suggests you only have the generic, basic function, Windows installed sound driver rather than the correct sound hardware driver. If this is the case, install the correct sound driver as step 1.

    Reviving old thread because I think I know the cause and a possible fix:

    I had this same issue (still do, now with Windows 10) with Windows 7.
    I'm not sure that this is actually it, BUT, the problem back then was coming from the nVidia drivers. I don't know why it had/has this problem and why it was never fixed, it may be related to older cards only as I'm too running an old card (Gigabyte GTX 560 SOC).
    The fix on Windows 7 was to actually install the manufacturer's drivers for the card, compatible with the version of Windows I was using and NEVER update it. As soon as I updated it, the problem with the stutter and freezes came back. I tested this by installing the same driver version, only this time provided by nVidia and the problem was once again present. The issue was not present with the manufacturer's drivers (downloaded from their website). Unfortunately Gigabyte has not released (and probably never will) a version of the drivers compatible with Windows 10. However, I suspect that the Windows 7 drivers will be compatible but I have yet to test this as the stutter is not really bothering me (except in games where the freezes are a pain and they tend to last longer, but I haven't had the time for games for a while now).
    You are welcome to try, just make sure you COMPLETELY remove the nVidia drivers (manually) before you try installing another version.
    Let me know the outcome.
    Cheers and good luck!
