Question Severe and consistent audio and video stutter ?

Earlier in the day, my power went out for a brief moment while I was using my PC regularly. When the power came back on and I turned my PC back on, there was an "Updating" symbol where I would usually see the BIOS information. From that point on, there has been severe audio and visual stuttering. I've restarted my PC more than a few times and tried a number of solutions that I saw here but none have worked. The audio and visual stutters do not always happen at the same time after restarting, the audio stutters (pops, clicks) aren't extremely frequent but occur progressively more often until they are roughly 3-5 seconds apart and last for roughly half a second. The video stutters are generally less severe but more frequent.

I've tried to clear my CMOS, done a clean boot of Windows 10, reinstalled all my drivers (I think?), updated my BIOS and disabled TPM in BIOS. I'm extremely, extremely inexperienced with computers and have basically been blindly following whatever advice I've seen in hopes that it might magically solve my problem. I don't know which information is relevant so I'm just going to give you all as much as I have. I've also run LatencyMon despite not knowing a thing about it because I've seen it requested in a couple threads, so I'm hoping that information can help you help me.

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 0:22:35 (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): 100796.20
Average measured interrupt to process latency (µs): 21.071987

Highest measured interrupt to DPC latency (µs): 100739.60
Average measured interrupt to DPC latency (µs): 15.776330

_________________________________________________________________________________________________________
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.

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: nortonsecurity.exe

Total number of hard pagefaults 6748
Hard pagefault count of hardest hit process: 2363
Number of processes hit: 56

The storport, ndis, Nvidia Kernel, and tcpip drivers have the highest execution, each over .5ms. There are an additional 6 driver files which are all over .1ms which are HDAudBus, rspLLL64, CLASSPNP, Wdf01000, dxgkrnl, and ntoskrnl.

Please help. I am so lost.
 
Try turning off your Norton Anti Virus to rule that out.(Running a virus scan wouldn't hurt) How many drives are you using and what kind? You can also try going into device manager and check item by item for any device driver update and installing them. How many things do you have have plugged into usb ports, other than your mouse and keyboard?
