Cool Merci für die Antwort. Ich habe den Check gemacht.
Das Problem scheint der WDf01000.sys Treiber zu sein. Hast Du eine Ahnung wie ich das lösen kann? BESTEN DANK
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 0:04:25 (h:mm:ss) on all processors.

SYSTEM INFORMATION
_________________________________________________________________________________________________________
Computer name: DESKTOP-E1TV17F
OS version: Windows 10 , 10.0, build: 19043 (x64)
Hardware: HP ProDesk 400 G6 MT, HP, 8599
CPU: GenuineIntel Intel(R) Core(TM) i7-9700 CPU @ 3.00GHz
Logical processors: 8
Processor groups: 1
RAM: 32606 MB total
_________________________________________________________________________________________________________
CPU SPEED
_________________________________________________________________________________________________________
Reported CPU speed: 30 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): 446.30
Average measured interrupt to process latency (µs): 6.087717
Highest measured interrupt to DPC latency (µs): 420.30
Average measured interrupt to DPC latency (µs): 1.890947

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): 3598.5620
Driver with highest DPC routine execution time: Wdf01000.sys - Kernelmodustreiber-Frameworklaufzeit, Microsoft Corporation
Highest reported total DPC routine time (%): 0.283596

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: tiworker.exe
Total number of hard pagefaults 2479
Hard pagefault count of hardest hit process: 408
Number of processes hit: 26
