Was wondering if someone here can help me to fix my problem? i'm in low budge pc and i dont have money to buy a new pc.
So hope you guys can help me

Your system appears to be suitable for handling real-time audio and other tasks without dropouts.
LatencyMon has been analyzing your system for 0:20:48 (h:mm:ss) on all processors.

SYSTEM INFORMATION
_________________________________________________________________________________________________________
Computer name: I-CAN-DO-IT
OS version: Windows 8.1 , 6.2, build: 9200 (x64)
Hardware: MS-7636, MSI, H55M-E33(MS-7636)
CPU: GenuineIntel Intel(R) Core(TM) i3 CPU 530 @ 2.93GHz
Logical processors: 2
Processor groups: 1
RAM: 3959 MB total

CPU SPEED
_________________________________________________________________________________________________________
Reported CPU speed: 3511 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): 653.853243
Average measured interrupt to process latency (µs): 1.537601

Highest measured interrupt to DPC latency (µs): 118.696820
Average measured interrupt to DPC latency (µs): 0.463837


_________________________________________________________________________________________________________
REPORTED ISRs
_________________________________________________________________________________________________________
Interrupt service routines are routines installed by the OS and device drivers that execute in response to a hardware interrupt signal.

Highest ISR routine execution time (µs): 64.741669
Driver with highest ISR routine execution time: dxgkrnl.sys - DirectX Graphics Kernel, Microsoft Corporation

Highest reported total ISR routine time (%): 0.311886
Driver with highest ISR total time: dxgkrnl.sys - DirectX Graphics Kernel, Microsoft Corporation

Total time spent in ISRs (%) 0.386145

ISR count (execution time <250 µs): 1172351
ISR count (execution time 250-500 µs): 0
ISR count (execution time 500-999 µs): 0
ISR count (execution time 1000-1999 µs): 0
ISR count (execution time 2000-3999 µs): 0
ISR count (execution time >=4000 µs): 0


_________________________________________________________________________________________________________
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.

Highest DPC routine execution time (µs): 300.702934
Driver with highest DPC routine execution time: nvlddmkm.sys - NVIDIA Windows Kernel Mode Driver, Version 341.96 , NVIDIA Corporation

Highest reported total DPC routine time (%): 0.259867
Driver with highest DPC total execution time: nvlddmkm.sys - NVIDIA Windows Kernel Mode Driver, Version 341.96 , NVIDIA Corporation

Total time spent in DPCs (%) 0.605883

DPC count (execution time <250 µs): 4740600
DPC count (execution time 250-500 µs): 0
DPC count (execution time 500-999 µs): 1
DPC count (execution time 1000-1999 µs): 0
DPC count (execution time 2000-3999 µs): 0
DPC count (execution time >=4000 µs): 0


_________________________________________________________________________________________________________
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: chrome.exe

Total number of hard pagefaults 1068
Hard pagefault count of hardest hit process: 413
Highest hard pagefault resolution time (µs): 107566.973227
Total time spent in hard pagefaults (%): 0.035623
Number of processes hit: 15

You could use HWMonitor, Core Temp, or HWinfo to monitor CPU speed and CPU temperature and see if your CPU is overheating and slowing down (throttling) due to heat. Run Intel Burn Test to put a load on you CPU while running one of the above to see what happens to CPU speed and temps under a heavy load.

Have you ever opened up the inside of your laptop and cleaned out the dust bunnies?

Yeah i did clean my pc like 2 days ago, not like Tech Yes City or LinusTech but i cleaned my motheboard with a brush, by vacumm but not with those amazing sprays just normally, and i activate in bios an option (Extreme memory profile) that improve my cpu stock from 2.9 to 3.5 and 1300mhz to 1600mhz memory but sistem was okay and still the same as 2.9 so didnt notice and improvement at all, the thing that i'm seeing that is working so far is the
