Hello.. I'm having some issues with DPC latency & stuff related I suppose :/.. I'm not a genius at this and could use some help.. Been bugging around with it for a while, that means; tested a lot of different nvidia drivers - flashed bios - tested every different bios setting (disabling everything throttle and power related etc. etc.)
But no solution so far..
My specs;
Mobo: Gigabyte Z77X-D3H rev 1.0
GFX: GTX 660
CPU: i5-2500
650W PSU
and my 1tb HDD just died recently so I'm running on SSD exclusively (40gb tho..)
Here's some LatencyMonitor stats;

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: services.exe
Total number of hard pagefaults 77
Hard pagefault count of hardest hit process: 57
Highest hard pagefault resolution time (µs): 124500,965789
