When pressing the caps lock key there is huge dpc latency spike witht the i8042prt.sys driver, it is only this key no other key on the keyboard causes this. I checked this 3 to 4 times with latencymon as well, this cause sthe entire system to lag out and stutter, however in any game that I am in such as cs2 this doesn't occur.
I have a working theory this may be realted to the Caps-Lock led however I have no idea how I would be able to test/fix this. I believe this may be the case as the led is triggered even when using a external keyboard.
I have tried a sfc /scannow, DISM commands as well, I have ran a system diagnostic, tried maxing out the power plan, and uninstalling and reinstall keyboard drivers. I have no idea what the issue is any steps or advice would be helpful.
These are the latency mon results _________________________________________________________________________________________________________
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 ISR 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 0:00:58 (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): 84717.80
Average measured interrupt to process latency (µs): 18.854754
Highest measured interrupt to DPC latency (µs): 84674.20
Average measured interrupt to DPC latency (µs): 12.022147

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.

DPC count (execution time >=4000 µs): 0
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 44
Hard pagefault count of hardest hit process: 28
