Hello,

I've been having DPC issues for a few months that come and go for undefined time periods. A few weeks ago I've reinstalled win10 on my new SSD and all of the DPC issues were gone. Recently, about a week ago the crazy stuttering and cracking came back. I've tried almost everything I can, performed all tests on my hardware, system restore points from times when I had no stuttering, every single suspicious driver reinstall. The problem seems to be persistent. Although yesterday I had a very nice evening with no DPC issues when I completely removed my Nvidia driver and reinstalled only the actual driver (without 3d, audio drivers, geforce experience) again. Today the stuttering came back again... I think that the GPU driver might be conflicting with networking, because when I uninstall it the stuttering is gone and LatencyMon shows no issues.

P.S. While writing the post, the issues fixed themselves, but I know they're coming back soon, so if someone could help me analyse where the problem comes from, that would be nice.

The trace and system files are here: DPC - Google Drive

Re: DPC problems

It looks like it may be the HD Audio device for your NVIDIA hardware. Try disabling the NVIDIA High Definition Audio through Device Manager and see if that reduces latency issues.
 
Re: DPC problems

Well, I haven't installed it to begin with (opted out the audio driver on NVIDIA driver installation) and it isn't in my Device Manager screen.
 
Re: DPC problems

Maybe try installing it? I just see an HDAudio generic driver in the same area as your slow DPC/ISR display card and network items.
 
Re: DPC problems

I always installed it before. It's half as bad without the NVIDIA driver though and installing it doesn't fix the problem. I've got my HD Audio Driver from Realtek as my audio driver.
 
Re: DPC problems

You said you've tried restore points, but have you tried completely removing newer drivers and installing older versions to see if there's a combination of display, audio, and network drivers that reduce latency?
 
Re: DPC problems

Yes, I did try that. As I've said in my initial post, the problem seems to disappear for a day or two when I completely uninstall NVIDIA Drivers and the reinstall just the video driver (without GFE, audio or 3D drivers). The problem disappears fully when I have no NVIDIA drivers installed, but that's not an option because of obvious reasons.
 
Hi! :wave:

Your ram is not in the MB QVL.
Did you seat your ram in 2nd and 4th slots (starting from cpu)?
Try to set your ram speed to 1333 (666MHz) instead of 1600 (800): your CPU should support till 1333 (at least, officially).
Did you seat your SSD in the SATA3_0 connector?
And did you try to switch it in SATA3_1?
 
The clock is currently set at 668.7 MHz on both sticks, rows 1-4 and 3-4. The SSD connector sits right above the HDD connector. I highly doubt the SSD connector could the problem because DPC stuttering first appeared before I installed it and the SSD does perform really well.
 
Yup. Try a clean boot:
  • Start, searchbox, type msconfig, press enter
  • Msconfig Services tab --> hide all Microsoft services and disable the remaining services
  • Msconfig Startup tab --> disable everything
  • Click ok, reboot, and see if the problem disappeared or remained
 
I just tried this and the problem is still there. The funny thing is, LatencyMon always shows different drivers causing the DPC issues, sometimes it's the tcpip.sys, sometimes it's Wdf01000.sys, sometimes dxgkrnl.sys or ndis.sys, ntoskrnl.exe nvlddmkm.sys is showing high dpc too...
 
Disconnect your pc from the mains, ***see the warning below***, unplug everything (connectors, ram sticks, graphics card), (remove the dust, gently and carefully), re-plug everything.

WARNING: Keep yourself grounded with the case to ensure there is no static buildup and discharge that might destroy any electrostatic discharge (ESD) sensitive devices. It is important to realize that the "threshold for human awareness" for a static shock is higher than the tolerance of ESD sensitive devices. In other words, you can shock and destroy a CPU, RAM module, or other sensitive device without even knowing there was a static discharge! Use an anti-static wrist-strap or frequently touch bare metal on the case to maintain your body at the same potential as chassis (case) ground.
