Hello, I've got an issue with a machine I built for myself that for the better part of a month I have not been able to pinpoint exactly what is going wrong. In games (specifically noticable in Fallout 4) I get Micro stuttering (visual). I started looking into what could cause this issue and ended up looking into DPC's from things like my video card drivers ect. I ran LatencyMon and found something I don't have a clue how to interpret. This is what I get just from loading firefox, or any application I have. There is a noticeable pause, the highest measured interrupt to process latency rises to whats seen here, and the program loads. The pagefault resolution time sits in the yellow at idle, and skyrockets once I load something like firefox along with the pause before it finishes loading.
I'm running an i5 7600k, a Gigabyte z270x gaming k7, and 16gb of corsair dominator platinum, along with my main OS on a 240gb corsair neutron ssd, and my games on a 480gb neutron. Having tried all I found (disable HPET, disable C-states, disable intergrated audio/network cards (in bios and windows) and even running with intergrated graphics) the issues are still present.
Any suggestions would be appreciated.

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 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 0:42:28 (h:mm:ss) on all processors.

_________________________________________________________________________________________________________
CPU SPEED
_________________________________________________________________________________________________________
Reported CPU speed: 3792 MHz
Measured CPU speed: 1 MHz (approx.)
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): 2629.324871
Average measured interrupt to process latency (µs): 1.527590
Highest measured interrupt to DPC latency (µs): 986.705667
Average measured interrupt to DPC latency (µs): 0.388137

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: svchost.exe
Total number of hard pagefaults 36788
Hard pagefault count of hardest hit process: 10048
Highest hard pagefault resolution time (µs): 499550.641614
