Hi
I have a freshly build PC with the following configuration: (First pic bellow)
I have had troubles with some (blue screen of death errors) these days ( second picture bellow WhoCrashed)
Then I updated my drivers and the errors reduced but i still have cracking sound and video and audio out of sync when playing live videos (Youtube).
Then I ran LatencyMon and the results were:
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. 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.
LatencyMon has been analyzing your system for 0:05:22 (h:mm:ss) on all processors.

SYSTEM INFORMATION
_________________________________________________________________________________________________________
Computer name: DESKTOP-JNJ22LC
OS version: Windows 10 , 10.0, build: 18363 (x64)
Hardware: ASUSTeK COMPUTER INC., ROG STRIX B450-F GAMING
CPU: AuthenticAMD AMD Ryzen 5 3600 6-Core Processor
Logical processors: 12
Processor groups: 1
RAM: 16310 MB total
_________________________________________________________________________________________________________
CPU SPEED
_________________________________________________________________________________________________________
Reported CPU speed: 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.
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): 20613.10
Average measured interrupt to process latency (µs): 10.653466
Highest measured interrupt to DPC latency (µs): 20607.40
Average measured interrupt to DPC latency (µs): 6.332420
_________________________________________________________________________________________________________
REPORTED ISRs
_________________________________________________________________________________________________________
Interrupt service routines are routines installed by the OS and device drivers that execute in response to a hardware interrupt signal.

Driver with highest ISR routine execution time: ntoskrnl.exe - NT Kernel & System, Microsoft Corporation
Highest reported total ISR routine time (%): 0.007934
Driver with highest ISR total time: ntoskrnl.exe - NT Kernel & System, Microsoft Corporation
Total time spent in ISRs (%) 0.008587

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.

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: perfwatson2.exe
Total number of hard pagefaults 27194
Hard pagefault count of hardest hit process: 18795
Number of processes hit: 21
