Hello.. After using pc for some time after boot, when im playing music or watching videos, there's a weird cracking sound every couple of seconds, like the pc can't keep up or something.
I tried using older and newer bios but nothing changed. I pulled this log of LatencyMon. Can you please take a look at it?
(the cracking repeats more often when pc is turned on for longer time, or when i play games etc..)

Thank you very much for your help.

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  0:03:16  (h:mm:ss) on all processors.

Reported CPU speed:                                   2594,0 MHz
Measured CPU speed:                                   1663,0 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.

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 (Ás):   2548,833229
Average measured interrupt to process latency (Ás):   6,140694


Highest measured interrupt to DPC latency (Ás):       2546,070052
Average measured interrupt to DPC latency (Ás):       1,317758

 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:                 ekrn.exe


Total number of hard pagefaults                       54
Hard pagefault count of hardest hit process:          12
