A friend gave me this computer and i've been having huge sound issues(crackle noise) when i am downloading something or even when playing games, when i searched the problem i downloaded LatencyMon to see what was the problem but i couldnt fix it, so here i am looking for 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. Also one or more ISR 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 2:27:01 (h:mm:ss) on all processors.

Computer name: JOÃO
OS version: Windows 8.1 , 6.3, build: 9600 (x64)
Hardware: N751JK, ASUSTeK COMPUTER INC.
CPU: GenuineIntel Intel(R) Core(TM) i7-4710HQ CPU @ 2.50GHz
Logical processors: 8
Processor groups: 1
RAM: 16266 MB total

CPU SPEED
_________________________________________________________________________________________________________
Reported CPU speed: 2494 MHz
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 (µs): 52951,481191
Average measured interrupt to process latency (µs): 10,672993
Highest measured interrupt to DPC latency (µs): 31812,025485
Average measured interrupt to DPC latency (µs): 3,714564

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 13856
Hard pagefault count of hardest hit process: 5872
Number of processes hit: 27
