The problem always lasts for a while and then closes

_________________________________________________________________________________________________________
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 0:05:00 (h:mm:ss) on all processors.

SYSTEM INFORMATION
_________________________________________________________________________________________________________
Computer name: SC-201703220025
OS version: Windows 8 , 6.2, build: 9200 (x64)
Hardware: B350GT5, BIOSTAR Group
CPU: AuthenticAMD AMD Ryzen 7 1700 Eight-Core Processor
Logical processors: 16
Processor groups: 1
RAM: 16337 MB total




_________________________________________________________________________________________________________
CPU SPEED
_________________________________________________________________________________________________________
Reported CPU speed: 2994.0 MHz
Measured CPU speed: 5216.0 MHz (approx.)


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): 2288.492290
Average measured interrupt to process latency (µs): 5.657487


Highest measured interrupt to DPC latency (µs): 2284.730572
Average measured interrupt to DPC latency (µs): 2.122862




_________________________________________________________________________________________________________
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): 72.064128
Driver with highest ISR routine execution time: Wdf01000.sys - 内核模式驱动程序框架运行时, Microsoft Corporation


Highest reported total ISR routine time (%): 0.003278
Driver with highest ISR total time: HDAudBus.sys - High Definition Audio Bus Driver, Microsoft Corporation


Total time spent in ISRs (%) 0.005762


ISR count (execution time <250 µs): 150016
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): 100482.224449
Driver with highest DPC routine execution time: storport.sys - Microsoft Storage Port Driver, Microsoft Corporation


Highest reported total DPC routine time (%): 2.986602
Driver with highest DPC total execution time: storport.sys - Microsoft Storage Port Driver, Microsoft Corporation


Total time spent in DPCs (%) 3.112902


DPC count (execution time <250 µs): 1151164
DPC count (execution time 250-500 µs): 0
DPC count (execution time 500-999 µs): 158
DPC count (execution time 1000-1999 µs): 0
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.




Process with highest pagefault count: none


Total number of hard pagefaults 0
Hard pagefault count of hardest hit process: 0
Highest hard pagefault resolution time (µs): 0.0
Total time spent in hard pagefaults (%): 0.0
Number of processes hit: 0
