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 0:01:48 (h:mm: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): 40401.989274
Average measured interrupt to process latency (µs): 21.833577
Highest measured interrupt to DPC latency (µs): 40399.423509
Average measured interrupt to DPC latency (µs): 18.335902

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): 67.533835
Driver with highest ISR routine execution time: HDAudBus.sys - High Definition Audio Bus Driver, Microsoft Corporation
Highest reported total ISR routine time (%): 0.032609
Driver with highest ISR total time: hal.dll - Hardware Abstraction Layer DLL, Microsoft Corporation
Total time spent in ISRs (%) 0.055720
ISR count (execution time <250 µs): 130327
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): 40421.570712
Driver with highest DPC routine execution time: ndis.sys - Драйвер NDIS 6.20, Microsoft Corporation
Highest reported total DPC routine time (%): 0.564494

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: chrome.exe
Total number of hard pagefaults 204
Hard pagefault count of hardest hit process: 105
Highest hard pagefault resolution time (µs): 50639.723237
Total time spent in hard pagefaults (%): 0.054422
Number of processes hit: 7
