Windows 10: nvlddmkm.sys/dxgkrnl.sys HI DPC latency /Stuttering CPU /USb DISCONNEC

I searched around, and it seems everyone has some version of this problem. But since mine is a little different, and some of those solutions DID NOT WORK, I'm posting my own problem here.

Problem
CPU spikes, local and internet video and mp3 player stutter. Internet speed loss/stutter
Usb DISsconnects and reconnects , causing computer functions to stutter.
Mouse disconnects permanently and has to be removed and reinserted.
EDIT: 46,000 NDIS.SYS DPC latency when entering a game like Battlefield 4








All of the bars used to be red to the max, but I did some things to rectify and reduce the latency. BUT the NVIDIA driver still persists to be a big problem.

Things I've done to try to solve the issue:
-Turned on HIGH performance and turned to CPU Disable on IDLE. I'm not sure if iwant to keep this setting, i like it taking a nap to reduce fan speeds.
--Ran an XPerf and saved the log.
Reseated Nvidia card and checked cables /power again.
-Observed IRQ conflicts. USB and ethernet are all sharing 18. Could not fix, but unsure if this is a problem.
-Removed Bitdefender, switched to Avira free. Scanned for Rootkit and full scan. Removing Bitdefender got the red bars down, but it's still not good enough, there's still some stutter and the Nvidia is still an issue.
-Installed Nvidia 361 driver. *FEB 2016.
-Disabled NVIDIA driver helper service in Services.msc
-Disabled HD audio from Nvidia (hdmi throughput)
-Updated to latest 7885 Bios, Updated all MSI support drivers from motherboard and app utilities
-Updated all drivers inside Device manager
-Used NVCleaner and installed Nvidia 365.10
-Removed Killer ethernet driver and installed Qualcomm.
-DO NOT own a WLAN card on this computer, so no it's not the problem.


What else to try?
REINSTALL Windows 7. I have heard some people have success in this. BUT if there's a way to avoid that, I will do that instead.
-Buy an AMD card. Well , I don't have such a wallet for that but I would if that means no more DPC latency!

OH AND THANKS FOR TRYING TO HELP! *Cool

Extremely high DPC Latency from Directx Graphics Kernel since Anniversary Update.

Same problem here. huge latency to dxgkrnl.sys and nvlddmkm.sys

First removed and then updated _everything_. No change whatsoever. Had no problems prior the update.

 

after windows update, audio lagged/crackling, high latency

edit: I have updated info quite a bit in posts, please check them out

My audio was working before updating windows (update released on Oct 27 apparently). Afterwards, I would get static and popping. Audio would quickly desync from the video. I tried updating sound driver,
uninstalling and restarting etc.. I did some research and found latencymon to identify which drivers are causing the latency.

The highest on the ISR + DPC count is USBPORT.SYS, dxgkrnl.sys, ataport.sys, and ndis.sys (in that order highest to lowest).

The highest execution column has ndis.sys, nvlddmkm.sys, dxgkrnl.sys, USBPORT.SYS, in that order.

I really don't know what all this means beyond that these drivers appear to be causing the issues, which didn't occur before I updated windows. I don't know how to fix these issues. Should I simply uninstall
the updates? (for some reason the PC doesn't have restore state enabled)

Here are the results from the latency monitor test.

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 0:14:41 (h:mm:ss) on all processors.

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: chrome.exe

Total number of hard pagefaults 1139

Hard pagefault count of hardest hit process: 302

Highest hard pagefault resolution time (µs): 533052.3450

Hi, you've done some good research on this difficult issue. You could check the source of your page faults:
See the 3rd screenshot here:
windows - What is Performance Monitor telling me when my page faults / second are high? - Super User

And try the same Nvidia driver as you used in Win 7.

Your PC seems pretty well specced, - can you check Win 10 compatibility with MSI, or any reports on their forum?

You might like to try checking this (just an idea):



Analyzing Interrupt and DPC Activity

 

Ok, so here we go. The monitor is going nuts.. but the CPU usage in TM isn't crazy at all. However, what is this gonna tell me to fix??





BTW, neither MSI or Nvidia sounded confident over the phone about my issue.
MSI just kinda agreed and nodded to whatever I said I would do to solve my issue and Nvidia just had me reinstall the driver again which did absolutely nothing.

 

Hi, have you tried what I suggested in the 1st 3 lines of my previous post? (Page faults) - addresses your LatencyMon report, 1st screenshot.

Also Win 7 driver..

Did MSI confirm your rig is Win 10 compatible?

Your last screenshot appears to confirm what you suspected.. driver interrupt contention.

Do you have any conflicts shown in Device Manager (View resource by connection)?

I can only suggest things that might point you in the right direction...

Fyi:
Analyzing Interrupt and DPC Activity

and Xperf from MS might be a way to go.

 

1. MSI on the phone confirmed my whole system is Win 10 ready. I have both an NVIDIA gpu and Graphics. They are very modern and were built during win 10 development.

2. I viewed on other pages in google that IRQs are not the same problem as in the past and we have only 15 IRQs, so many will be shared. At the moment, the USB and Ethernet share the same 18 IRQ (both on the MSI motherboard). Anyways, i uninstalled them all and rebooted and they both returned to 18. There's really no way to change IRQs in windows 10.

3. I have tried all of those things above, but they are really not up my alley in understanding.. It's not a language i really know. Anyways, both Firefox and Opera cause high page faults. But so does my computer going idle overnight. I have tried the process explorer here, but it really doesn't tell me anything. I did post the results here and above. Btw, yes I used a driver from back in early 2015, but that still didn't solve anything (353.xx)

 

If this is a bizarre driver issue, you may want to try a freeware program called DDU. Then reinstall your driver from an updated download.

DDU has resolved issues for me, in the past.

Oops. Just reread your post. I misread it as an nvidia driver issue. A few review sites discuss this dpc latency issue. A mobo freq is mis-set in bios. A minor tweak ( ring voltage?) may be needed, as well as a bios update. Details escape me, but there was a lot of discussion on this and digging before the cause was found. Try Hardforum.com

Edited to add a link: Gigabyte GA-Z170X Gaming 7 DPC Latency Issue | [H]ard|Forum

 

Thanks for replying
- I did use DDU actually to clean out drivers.
-I'm using the default 125 multiplier in BIOS for the motherboard. It's actually 125.03 but I can't change it seems. Ring voltage is set to autio.
-BIOS is updated to latest version.
-Hardforum article on DPC latency didn't solve my issues.

Lot's of strange CPU spikes here, but I haven't noticed any audio dropouts when running 4x 4k Videos on my PC. What is really bothersome is the USB disconnects though! Even without any browser open, the spikes look very similar.




OTHER:
I checked my other 2 laptops, one is my mother's but she barely uses it except to check the lottery...lol . It's brand new and really bare with no software on it. My own laptop uses onboard video but it has ndis.sys and other high dpc latency.

So both of them have high DPC latency. I think the issue is Windows 10. The hardware /software is just bare minimum on that laptop but it still has latency issues.

Currently in touch with Nvidia, they wanted my CPU Z and GPU Z log stats
