Windows 10: DPC Routines executing for Too Long, Popping Noises and Stutter

For about 3 months, I have been having problems with the Stutter of all applications on the system, from startup that sometimes randomly went away after leaving the computer on for a while. I have been looking for a solution for a while now and decided to post here. I have updated BIOS, all The Drivers, and nothing has worked yet.


My system specs are as follows:

OS: Windows 10 Pro 64bit, Version 10.0.19042

Motherboard: Gigabyte Z170X-UD3-CF

CPU: Intel i7-6700 CPU @ 3.40GHz

GPU: NVIDIA Geforce RTX 3070

RAM: 32 GB


I have the Transcripts from Latency Monitor below, as recommended in Other Threads.

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. One problem may be related to power management, disable CPU throttling settings in Control Panel and BIOS setup. Check for BIOS updates.

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.

DPC routines executed too long. Popping and clicking sound.

Hello.. i am experiencing this Problem now since.. i would say around 2-3 Month. I have swapped out my Mainboard, changed my Ram, changed my PowerSupply, reinstalled windows, set my power settings to 100% (giving my CPU 100% all the time) etc... still the
clicking remains whenever i open something or something needs to load in the background... Here are some results from latency mon...

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. 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.

"One or more DCP routines that belong to a driver running in your system appear to be executing for too long."

So I've been having some stuttering issues in games and big performance drops then it'll go back to normal. I've also noticed that my friend with the exact same computer (Dell G7, same specs) doesn't get these and his runs smoother. I ran the whysoslow
monitoring tool from Resplendence, and that told me to run LatencyMon. Here is the result (I bolded the important parts):

DPC Latency Issue - Random audio popping/crackling

I have been having audio popping/crackling for a few months now. I also get random 3-10 second intervals of pure white noise/static come out of nowhere when watching a video or listening
to music.

I'm not sure how to fix it.

I've tried:

• 
  
  Running memtest(no problems)
  
  Resetting my cpu overclock
  
  Reinstalling audio drivers, updating mobo
  
  Turning off fast startup
  
  Changing/reverting audio formats
  
  Updating graphics driver
  
  and possibly a few others I don't remember.
  

Any help would be greatly appreciated. Thank you.

CONCLUSION

_________________________________________________________________________________________________________

Your system seems to be having difficulty handling real-time audio and other tasks. You may experience drop outs, clicks or pops due to buffer underruns. One or more DPC 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 0:17:47 (h:mm:ss) on all processors.

SYSTEM INFORMATION

_________________________________________________________________________________________________________

Computer name: SHAAN

OS version: Windows 10 , 10.0, build: 16299 (x64)

Hardware: MS-7A11, MSI, Z170A KRAIT GAMING 3X (MS-7A11)

CPU: GenuineIntel Intel(R) Core(TM) i5-6600K CPU @ 3.50GHz

Logical processors: 4

Processor groups: 1

RAM: 16344 MB total

_________________________________________________________________________________________________________

CPU SPEED

_________________________________________________________________________________________________________

Reported CPU speed: 3504 MHz

Measured CPU speed: 1 MHz (approx.)

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.

WARNING: the CPU speed that was measured is only a fraction of the CPU speed reported. Your CPUs may be throttled back due to variable speed settings and thermal issues. It is suggested that you run a utility
which reports your actual CPU frequency and temperature.

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 (µs): 760.402271

Average measured interrupt to process latency (µs): 2.408340

Highest measured interrupt to DPC latency (µs): 758.941083

Average measured interrupt to DPC latency (µs): 0.908718

REPORTED ISRs

_________________________________________________________________________________________________________

Interrupt service routines are routines installed by the OS and device drivers that execute in response to a hardware interrupt signal.

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.

Driver with highest DPC routine execution time: storport.sys - Microsoft Storage Port Driver, Microsoft Corporation

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 (µs): 0.0

Total time spent in hard pagefaults (%): 0.0

Number of processes hit: 0
