Hey guys I'm having a serious issue with my pc. It started out as occasional pops in audio while playing games a month ago, and then it turned out to be a cracking buzzing unbearable sound and it happens only when playing games (absent when watching video playing music while on photoshop or some other program).
The games run buttery smooth and I experience no lags or fps drops.
The sound is not from any hardwares inside my pc.
The cracking sound exists as long as any game is running (it disappears when game is minimized, nd the game audio is clear) and it doesn't matter whatever headphones or speakers I connect to.
During a fresh boot up i could play for maybe 15 to 20 minutes or less without this noise slowly increasing the more I play.
And while playing this buzzing cause to disconnect and connect my headphones or external speakers connected causing the realtek notification to pop up
I thought it was from the windows 10 anniversary update but I did a clean install of windows 8.1 problem still exist.
Things I've already tried:
Updated all drivers even installed older versions of Nvidia driver(every update was or install was made after removing drivers using DDU).
Did a clean install of windows changed from win10 to 8.1
Tweaked BIOS settings such as Disabling/Enabling HPET (both on bios as well as os), Virtualization, and few other tweaks (didn't underclock or overclock as I've never oc'd my processor before)
Changed CPU and GPU to preffered maximum performance under power saving.
Removed GPU and plugged in to onboard VGA.
Tried connecting pc to a different power outlet.
Removed the chasis and front cover.
Checked for DPC Latency and tried disabling each driver.
Latencymon showed DirectX kernal and some nvidia to have high execution times.
I've honestly never had this problem before, it just randomly started and it feels like I've tried alost every solution.
My PC specs:
CPU: Intel Core2Quad Q6600 2.4Ghz
Motherboard: Digilite Dl-g41-mx3-lte
GPU: Nvidia 730GT 2Gb DDR3
Ram: 2×2GB DDR3 Adata
PSU: Zebronics 450W
No thermal issues.
Here is a screenshot and stats from LatencyMon

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. Also 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 0:02:47 (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.

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: metroll.exe
Total number of hard pagefaults 672
Hard pagefault count of hardest hit process: 402
Highest hard pagefault resolution time (µs): 192291.150
