Background: This may be the same root of an issue that's troubled me some time, and gotten worse. That issue is a persistent crash to boot, with no bluescreen. It sometimes is accompanied by a freeze or distorted audio...
Much like one of them there creepypasta the youths sometimes talk about! But most often it's just a pause, and then an immediate cycle to boot. I am unfortunately aware that I know nowhere near enough to solve the problem, and more then anyone else in my area, including the technical services available to me. Thus, I turn to you, dear friends, in the hope you may help me. That however, may be a separate issue. Due to having tested the HDs, with seagate's long generic, run scandisk, kept an eye on crystal disk, gotten my drivers in order, I'm pretty sure it's either the motherboard or the power supply... And I'm 99% sure it's the latter. A new PSU is coming and I'll be testing it shortly.
That doesn't address the issue of the audio buzzing/latency. I've tried all the solutions I can think of/find online, such as disabling one or both audio drivers (Nvidia High-Def/Realtek), disabling/upgrading WLAN, etc.
It is inconsistent, sometimes frequent, sometimes silent for hours. Here's latency's text report...

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.
LatencyMon has been analyzing your system for 2:05:32 (h:mm:ss) on all processors.

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): 18234.10
Average measured interrupt to process latency (µs): 5.420595
Highest measured interrupt to DPC latency (µs): 18230.50

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: nms.exe
Total number of hard pagefaults 3872
Hard pagefault count of hardest hit process: 2440
Number of processes hit: 19

... And here's an image.
Unfortunately, I tried flashing the BIOS first thing, so I'm uncertain about whether it's that. (Well, and we could go back to the motherboard being bad... But I don't know how to reliably test that.)
Info:
Windows 10 Pro 64-bit
AMD Ryzen 7 3700X 8-Core Processor
64.0GB RAM
ASUSTeK COMPUTER INC. TUF GAMING X570-PLUS (Driver: 4408)
GeForce RTX 2070 SUPER (Driver: 31.0.15.3129/531.29)
Broadcom 802.11ac Network Adapter
Two 12 TB WD HDs, one OS, one storage. Both are apparently in good health!
Hopefully, this is a good start. Best..!
