For a while now I have noticed when I'm playing games I receive audio dropouts followed by freezes at a significant regularity. I have recently downloaded LatencyMon and it appears it is coming from storport.sys and ndis.sys. I have researched for hours trying to solve this but I can't quite figure it out. I saw another thread similar to my issue, but their fix didn't help me at at. I'm starting to think it is an hardware issue but I would like to check before dumping hundreds of dollars. It also might be important to note that I did build this computer.
LatencyMon:
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 1:34:44 (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): 1894.50
Average measured interrupt to process latency (µs): 6.416907
Highest measured interrupt to DPC latency (µs): 1568.60

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: msmpeng.exe
Total number of hard pagefaults 66792
Hard pagefault count of hardest hit process: 18757
Number of processes hit: 116
