Hi, I'm having an issue where my computer's audio and video stutters for 3 to 4 seconds seemingly every few hours. I don't have my own recording, but this video from 0:37 to 0:40 kind of shows what the audio sounds like. The rest of the video doesn't apply and their video is smoother than mine during the stuttering - my video matches the audio stutters. The stutters seem to happen whenever, regardless if i'm playing a game, watching a video, browsing the internet, or just sitting at my desktop.
I've made sure my drivers are updated.
My specs are:

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 1:29:58 (h🇲🇲ss) on all processors.

Computer name: <Redacted>
OS version: Windows 10, 10.0, version 2009, build: 19044 (x64)

Reported CPU speed (WMI): 360 MHz
Reported CPU speed (registry): 360 MHz
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.

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): 323.20
Average measured interrupt to process latency (µs): 5.689547
Highest measured interrupt to DPC latency (µs): 319.90
Average measured interrupt to DPC latency (µs): 2.500604

Highest reported total ISR routine time (%): 0.000374

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.

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.
