i have been getting latency issues on a new build and i tried to fix it but nothing worked. i updated all my drivers with driver easy, fresh installed windows and tried some suggestions i found online. i have latest bios
system specs:
mother board: biostar a320MH pro
cpu: amd ryzen 5 1500x
gpu: amd radeon R7 200 series (hd 7770) 1Gb
ram 8GB 2666
ssd: kingston 120GB
HDD: seagate barracuda 1TB
bios american megatrends ver. 5.13
i used latencymon to see what was causing latency and this is the result

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 0:34:14 (h🇲🇲ss) on all processors.

SYSTEM INFORMATION
_
Computer name: DESKTOP-4GDK1FT
OS version: Windows 10 , 10.0, build: 17763 (x64)
Hardware: A320MH PRO, BIOSTAR Group
CPU: AuthenticAMD AMD Ryzen 5 1500X Quad-Core Processor
Logical processors: 8
Processor groups: 1
RAM: 8144 MB total
_
CPU SPEED
_
Reported CPU speed: 3493 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.
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): 101295.80
Average measured interrupt to process latency (µs): 7.286705
Highest measured interrupt to DPC latency (µs): 101292.90
Average measured interrupt to DPC latency (µs): 4.360704

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): 219.859719
Driver with highest ISR routine execution time: Wdf01000.sys - Kernel Mode Driver Framework Runtime, Microsoft Corporation
Highest reported total ISR routine time (%): 0.005908
Driver with highest ISR total time: Wdf01000.sys - Kernel Mode Driver Framework Runtime, Microsoft Corporation
Total time spent in ISRs (%) 0.006018
ISR count (execution time <250 µs): 963504
ISR count (execution time 250-500 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): 100917.855711
Driver with highest DPC routine execution time: storport.sys - Microsoft Storage Port Driver, Microsoft Corporation
Highest reported total DPC routine time (%): 0.290777

DPC count (execution time 2000-3999 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: steamwebhelper.exe
Total number of hard pagefaults 622
Hard pagefault count of hardest hit process: 143
Number of processes hit: 20
