Question Very high latency, and peripherals stop working ?

Im really hoping someone can help me out here. I've been googling for months and nobody has fixes that worked for me yet.
For some reason when im playing a game, ill get huge latency problems, my audio cuts out and my keyboard and mouse cut out as well.
Its not specific to one game, and it doesnt always happen. ESO and DND Dark Alliance it happens frequently. Less demanding games like The Binding of Isaac or Hades, it happens less often, but still does every now and then.
Ive tried a new PSU, underclocking the CPU a bit, RAM on and off of XMP, Windows refreshes, Bios updates. Im at a loss here and would really love some help.

I ran LatencyMon for about 38 minutes and walked away. For the first 10 minutes, it was fine. But when i came back, it looks like it still had problems at some point.


The above image I captured from GPU-Z of when it looks like i had a huge lag spike while LatencyMon was testing.


The above image here i captured while playing DND Dark Alliance. Grabbed the MAX of each stat. The issues were happening constantly after i started up the game.

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 0:38:19 (h🇲🇲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): 276.10
Average measured interrupt to process latency (µs): 4.323172

Highest measured interrupt to DPC latency (µs): 273.20
Average measured interrupt to DPC latency (µs): 1.323452


_
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): 165.662121
Driver with highest ISR routine execution time: dxgkrnl.sys - DirectX Graphics Kernel, Microsoft Corporation

Highest reported total ISR routine time (%): 0.001074
Driver with highest ISR total time: dxgkrnl.sys - DirectX Graphics Kernel, Microsoft Corporation

Total time spent in ISRs (%) 0.001201

ISR count (execution time <250 µs): 21098
ISR count (execution time 250-500 µs): 0
ISR count (execution time 500-999 µs): 0
ISR count (execution time 1000-1999 µs): 0
ISR count (execution time 2000-3999 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): 2242.680768
Driver with highest DPC routine execution time: nvlddmkm.sys - NVIDIA Windows Kernel Mode Driver, Version 471.11 , NVIDIA Corporation

Highest reported total DPC routine time (%): 0.018420
Driver with highest DPC total execution time: ndis.sys - Network Driver Interface Specification (NDIS), Microsoft Corporation

Total time spent in DPCs (%) 0.023613

DPC count (execution time <250 µs): 1733199
DPC count (execution time 250-500 µs): 0
DPC count (execution time 500-999 µs): 34
DPC count (execution time 1000-1999 µs): 3
DPC count (execution time 2000-3999 µs): 1
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: nvcontainer.exe

Total number of hard pagefaults 61451
Hard pagefault count of hardest hit process: 23098
Number of processes hit: 75

Welcome to the forums, newcomer!

Am I right to assume that you've got BIOS version F13j on your motherboard at the time of writing? As for your reinstalling your OS, did you refabricate your installer using Windows Media Creation Tools prior to reinstalling your OS? As for your ram's profiles, go into BIOS, manually set ram frequency, voltage and timings as stated on the ram's stickered side or it's packaging.

With regards to your stuttering, what storage drives are you working with and how are the populating the slots on the motherboard?

Hey thanks for the welcome and reply!

I'll have to check the bios version after work today, but i did use the Gigabyte dashboard thing to update my bios and other drivers just 2 days ago, so hopefully that gave me the latest.

The OS reinstalling, i did not exactly uninstall and reinstall windows. I did a command prompt (SFC /scannow) to verify the integrity of my OS files and it came back saying it fixed a few corrupted files. Maybe i should do a fresh reinstall. If i do, should i refabricate how you said?

For the RAM, would that be basically creating my own XMP profile for the RAM, instead of using whats provided in the Bios?

I have one 500GB NVME only used for OS bootup, nothing else on it. One 1TB NVME for games. And one 2TB HDD for lesser games and various media. Both NVME are slotted on the motherboard on my 2 NVME slots, the HDD is mounted in the back side HDD slot and connected via Sata cable. And all drives were bought brand new when i built this pc about a year ago.
