Since May, I've noticed that my computer was having audio clicks and pops, especially with graphically demanding operation, such as watching videos on YT and playing games. This has been driving me crazy, as I cannot use my PC properly anymore.
I've tried everything so far: I've tried to disable drivers, to update my bios, to disable cpu throttling in Control Panel, to update my motherboard's drivers, and recently I've even reset my whole system (which ran Windows 10 at the time), and everything on my hard drives has been whiped out (even though my usb wifi adapter was still running so I think it did not uninstall all the drivers). Right now I've downgraded my system to Windows 7, but it didn't help. I've ran LatencyMon after playing PUBG for 50 seconds, but I had to quit. Please help me, I'm about to give up on this computer. Here's the 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 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 0:08:16 (h:mm:ss) on all processors.

SYSTEM INFORMATION
_________________________________________________________________________________________________________
Computer name: MASARELLINI
OS version: Windows 7 Service Pack 1, 6.1, build: 7601 (x64)
Hardware: ASUSTeK COMPUTER INC., RAMPAGE IV FORMULA
CPU: GenuineIntel Intel(R) Core(TM) i7-3820 CPU @ 3.60GHz
Logical processors: 8
Processor groups: 1
RAM: 16323 MB total
_________________________________________________________________________________________________________
CPU SPEED
_________________________________________________________________________________________________________
Reported CPU speed: 3602 MHz
Measured CPU speed: 1 MHz (approx.)
Note: reported execution times may be calculated based on a fixed reported CPU speed. Disable variable speed settings like Intel Speed Step and AMD Cool N Quiet in the BIOS setup for more accurate results.
WARNING: the CPU speed that was measured is only a fraction of the CPU speed reported. Your CPUs may be throttled back due to variable speed settings and thermal issues. It is suggested that you run a utility which reports your actual CPU frequency and temperature.

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): 36893,886156
Average measured interrupt to process latency (µs): 2,891571
Highest measured interrupt to DPC latency (µs): 130,200338
Average measured interrupt to DPC latency (µs): 0,744494

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.

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: svchost.exe
Total number of hard pagefaults 11027
Hard pagefault count of hardest hit process: 2723
Highest hard pagefault resolution time (µs): 501755,462798
Total time spent in hard pagefaults (%): 0,780657
Number of processes hit: 34
