I've been suffering from audio issues for a while and just tolerating them but I suffered a BSOD the other week and thought it was probably about time I tackled the issue.
I've been running LatencyMon today and it's identified:
I've done a few troubleshooting maintenance tasks and they haven't helped so far:
Advanced disk cleanup
I could do with a hand trying to get to the bottom of this. I've got some basic windows knowledge, but it's better to consider me a trained monkey with respect to resolving this. Thanks!

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 0:12:38 (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): 51242.881969
Average measured interrupt to process latency (µs): 7.690992
Highest measured interrupt to DPC latency (µs): 51238.391420
Average measured interrupt to DPC latency (µs): 4.350270

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.

Driver with highest DPC routine execution time: ndis.sys - NDIS 6.20 driver, Microsoft Corporation
Highest reported total DPC routine time (%): 0.458949

Total time spent in DPCs (%) 1.144926
DPC count (execution time <250 µs): 4337128
DPC count (execution time 250-500 µs): 0
DPC count (execution time 500-999 µs): 24869
DPC count (execution time 1000-1999 µs): 2330
DPC count (execution time 2000-3999 µs): 4
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: outlook.exe
Total number of hard pagefaults 27041
Hard pagefault count of hardest hit process: 13362
Number of processes hit: 13
