Question Slow PC / Audio Popping / OBS Studio Crashing

Hey Guys,

I've searched almost everywhere online and constantly am redirected to random forums or pages mostly on this site. I've been having a problem where my stream preview will freeze on OBS Studio and my stream crashes. I am then met popping audio, slow performance, and high results on LatencyMon. OBS has to be force closed. I have to restart my PC, then after the restart everything is completely fine. It randomly happens at some point. No signs on Open Hardware Monitor, nothing reach 100% performance (not even a single CPU core), and temps are all normal.

LatencyMon:
"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. 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."

Steps I have tried but not exactly sure if they are related:
  • Updated Bios
  • Updated Graphics Drivers
  • Disabled CPU Throttling, Speed Step, All other related throttling things in the MOBO
  • Updated sound drivers from the MOBO website
  • No XMP Profile
  • Uninstalled MSI Afterburner
  • No background security software running
  • No overclocks
Specs:
MOBO: ASRock z390 Pro4
OS: Windows 11
CPU: i9-9900k
GPU: 2080 Super
RAM: 32gb 2666mhz

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): 434.50
Average measured interrupt to process latency (µs): 10.194156

Highest measured interrupt to DPC latency (µs): 429.50
Average measured interrupt to DPC latency (µs): 7.247151


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

Highest ISR routine execution time (µs): 135.401111
Driver with highest ISR routine execution time: dxgkrnl.sys - DirectX Graphics Kernel, Microsoft Corporation

Highest reported total ISR routine time (%): 0.166886
Driver with highest ISR total time: dxgkrnl.sys - DirectX Graphics Kernel, Microsoft Corporation

Total time spent in ISRs (%) 0.216197

ISR count (execution time <250 µs): 148595
ISR count (execution time 250-500 µs): 0

ISR count (execution time 1000-2000 µs): 0
ISR count (execution time 2000-4000 µs): 0
ISR count (execution time >=4000 µs): 0


_
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.

Highest DPC routine execution time (µs): 499.158889
Driver with highest DPC routine execution time: nvlddmkm.sys - NVIDIA Windows Kernel Mode Driver, Version 497.09 , NVIDIA Corporation

Highest reported total DPC routine time (%): 0.233588

DPC count (execution time 1000-2000 µs): 0
DPC count (execution time 2000-4000 µs): 0
DPC count (execution time >=4000 µs): 0


_
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: msmpeng.exe

Total number of hard pagefaults 38
Hard pagefault count of hardest hit process: 12
Number of processes hit: 11

Curious if there is a fix for this?
Was playing Dead by Daylight earlier and out of nowhere my PC started stuttering. I started having tons of sound problems and got crazy results on latencymon. Posted here:
