    directX and Nvidia drivers causing high DPC? FIX: DISABLED ONBOARD GRAPHICS CARD

    I am largely a PC newbie, but will try to include as much detail as I can: I recently put together my first water cooled PC, and have been experiencing audio drop-outs, pops, and occasionally lag and drops in FPS during gaming. For the most part, the audio problem arises when streaming online, particularly when opening a new window or other program or when the video is loading. Im running an ethernet cable and generally get 200-250Mbps (most recent speedtest: http://www.speedtest.net/result/7079366170.png), so I dont think its the connection. Recently, audio has begun to drop out while gaming too, and I have to go to the realtek audio manager and disable then enable the device to get it to turn back on. Im using a Samsung 4k TV through an HDMI cable as my monitor, the problem is not in the speakers themselves, they're fine when using the tv directly (via netflix, amazon, or other in-TV programs).

    high DPC latency seems to be common so here are some of the things I have tried (and have been unsuccessful with) while checking with latencymon:

    changed XMP profiles
    disabled all audio drivers and ran one at a time
    revert to an old NVIDIA driver with clean install (388)
    reinstall current NVIDIA driver w/o any other drivers (audio, 3d, phsyx, etc)
    update BIOS (both to latest, then to slightly older version to avoid buggy chipset fix)
    ran MEMTEST (no issues found)
    tried running audio directly from mobo instead of GPU
    turned off mobo audio in bios
    updated all drivers w/ iobit driver booster
    disabled avast/malwarebytes
    disabled network adapter drivers

    I have not tried:
    messing with C states in bios
    enabling driver verifier
    starting w/o gpu or trying different pcie slots


    I would not be surprised if Im just doing something stupid or have something activated/deactivated that shouldnt be... this build has been a learning process, but Im floored that anyone would need to jump through this many hoops and spend all this $ on a product that doesnt work 100%
    here are the some of the stats, if Im missing anything let me know:

    Dxdiag and msinfo.zip

    Have you re-installed the OS? no
    CPU i7-8700 CPU @ 3.20GHz, 3192 Mhz, 6 Core(s), 12 Logical Processor(s)

    Video Card EVGA GeForce GTX 1080 SC GAMING ACX 3.0 8GB (PCIE 16 slot)
    MotherBoard - (if NOT a laptop) Z370 AORUS Gaming 7
    Power Supply - brand & wattage (if laptop, skip this one) EVGA SuperNOVA 850 G2 gold fully modular
    Is driver verifier enabled or disabled? disabled
    What security software are you using? (Firewall, antivirus, antimalware, antispyware, and so forth) avast (subscription), malwarebytes (subscription)
    Are you using proxy, vpn, ipfilters or similar software? no
    Are you using Disk Image tools? (like daemon tools, alcohol 52% or 120%, virtual CloneDrive, roxio software) no
    Are you currently under/overclocking? Are there overclocking software installed on your system? unsure, I havent changed settings on overclocking but the system comes w/ OC software

    latencymon: directx and nvidia drivers seem to be the most frequent, but the audio driver (HDAudBus.sys) also pops up occasionally
    _________________________________________________________________________________________________________
    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 0:09:54 (h:mm:ss) on all processors.

    Re: completely stumped, directX and Nvidia drivers causing high DPC?

    The thing we're missing from the posting instructions is the Sysnative reports. This includes the crash dumps, event viewer and other info. That would sure help if you would upload it. Thanks.

    Hi chef,

    to Sysnative.

    Could you please follow steps E and F of POSTING INSTRUCTIONS for DPC/ISR latency, stuttering, cracks/pops, the trace file is the only thing that's missing

    Re: completely stumped, directX and Nvidia drivers causing high DPC?

    There weren't any dump files produced. The errors in the event viewer all point to Malwarebytes. Please make sure you are running the latest version. You can use the Check For Updates in the program itself. If that doesn't help you can uninstall it then redownload it and reinstall it.

    ok! ill give this a go when i get home, thanks!

    definitely running the newest version, will also try an uninstall/reinstall. thanks!

    Re: completely stumped, directX and Nvidia drivers causing high DPC?

    OK, so the SDK trace was too big to attach (10mb), but here's a drive link:
    trace2-22.zip - Google Drive

    let me know if that doesnt work. It looks like chrome comes up the most in the trace, but the latency issue pops up even w/ firefox and when playing steam games. maybe a complete chrome uninstall is necessary?


    also, uninstalled malwarebytes, no fix. I also booted in IGFX instead of the GPU and the latency was still there, AND it went BSOD once as well...that hadnt happened with the GPU as of yet

    here was the latencymon run while in IGFX

    It got saved as an .etl file that I can't open.

    should I save it under a different file type? just followed the instructions for steps E and F here (POSTING INSTRUCTIONS for DPC/ISR latency, stuttering, cracks/pops). Or was it a drive issue? would a dropbox link change anything (Dropbox - trace.etl ) forgive my lack of experience!

    Re: completely stumped, directX and Nvidia drivers causing high DPC?

    the drive file was a zipped file, so maybe thats why? the dropbox link should work

    Re: completely stumped, directX and Nvidia drivers causing high DPC?

    Windows Performance Kit from Windows Assessment and Deployment Kit needs to be installed to open the trace file properly.

    Please revert the driver installs done by Driver Booster and uninstall all programs from IObit, the software of IObit is known for causing issues (especially Advanced SystemCare and Driver Booster) and/or can be replaced with better alternatives.

    Thanks AxeO. I was searching for how to open them.

    will do, tho the latency issue showed up before any IObit program installation

    He was telling me how to open the file Chef. You don't need to download it. At least I don't think so.

    Re: completely stumped, directX and Nvidia drivers causing high DPC?

    Chef already has the kit installed to provide us the trace file.

    @chef, it doesn't matter if the problem started before IObit was installed, there are enough situations where IObit rendered systems unable to boot mainly after using Advanced SystemCare.
    chef says thanks for this.

    ok, do I need to worry about any potential files that arent deleted by the uninstall?

    also, any chance this latency stuff is caused by a PCIe riser cable? it still showed up when I booted on IGFX but im curious

    Not that I'm aware of. Of course, if there are any problems use either a system restore point or different system backup (if any).

    Re: completely stumped, directX and Nvidia drivers causing high DPC?

    read on another forum that IRQ (conflicts) might be the cause, so checked out my device manager (attached). Any idea why this USB 3.1 controller would be taking up so many slots? also, correct me if im wrong but it seems to be competing with everything else using a PCI? or is IRQ not a concern?

    Re: completely stumped, directX and Nvidia drivers causing high DPC?

    I don't see IRQ data in my device manager, what does msinfo32 say in Hardware Resources > IRQs?

    will check when i get home, but to see IRQ in device manager, click the 'view' tab, then sort 'resources by type' and it should be an available tab. My PCI stuff was at the bottom of that list
