Hello everyone,
I'm going crazy here because I can't assess what's going on with the PC or whether its behavior is just normal. Sometimes, as mentioned above, I get spikes of up to 2,000 from the mentioned drivers. Sometimes it's Nvidia, other times DirectX, or classpnp. Right now, the PC has been running for over 4 hours. Of that, 2 hours idle and 2 hours gaming. Sometimes the spikes occur without any changes made to the drivers, etc. Sometimes after 2 minutes, sometimes, as seen in the pictures, not at all. The latest NVIDIA driver is the worst. With it, Nvidia is always at the forefront and constantly. I have uninstalled the Realtek sound driver, as it ALWAYS spikes with HDAD. What do you think is going on?

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): 194,40
Average measured interrupt to process latency (µs): 3,825565
Highest measured interrupt to DPC latency (µs): 192,20
Average measured interrupt to DPC latency (µs): 1,180133

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 47485
Hard pagefault count of hardest hit process: 27529
Number of processes hit: 56
