Failing PSU? Game stutters pretty much fixed after turning off CPU overclock - but worked fine with OC before ?
I've been trying to diagnose an issue with my games micro-stuttering. The issue initially started out of no where with no issues previously. I noticed the lamp on desk would flicker when the stutters would get worse. I thought it might have been house power. Tested it out at another house, still got the micro-stutters. I got a BSOD that said BattleEye was the culprit upon opening Tarkov (game). PC restarted fine. Then the next morning I had to switch the PSU power button off and then on to start the computer up again. The other day I set my BIOS to default settings, and re enabled XMP (effectively un-doing CPU overclock), and micro stutters are pretty much gone, but still have been experiencing some random FPS drops. Could it be my PSU? I am also starting to get some audio clicks and crackling.
Edit; Reverting overclock ended up not being a fix.

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. At least one detected problem appears to be network related. In case you are using a WLAN adapter, try disabling it to get better results. 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 0:46:13 (h🇲🇲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): 882.90
Average measured interrupt to process latency (µs): 3.229831
Highest measured interrupt to DPC latency (µs): 881.50
Average measured interrupt to DPC latency (µs): 1.294563

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: msmpeng.exe
Total number of hard pagefaults 28090
Hard pagefault count of hardest hit process: 21427
Number of processes hit: 47
