Hello, firstly my spec (my computer is about 4 years now, fyi.):
P7P55-LX
i3-540 3.07GHz (Never OC)
GTS 450 (Never OC)
4GB Kingstone DDR3
Western 500GB Blue
and 450W of PSU.
Well, lately I got 2 issues on my hands.
When I open any youtubes (chrome, firefox and IE) I got the distorted sound, also I did updated flash player tho. but the problems still occurs. I suspects that ndis.sys, USBPORT.sys and tcpip.sys are the causes of those things.
also another problem is, When I'm playing League of Legend or Team Fortress 2, I got the "Display driver has stopped work" and/or when I'm trying to play youtube with 4-5 videos together, its crashed. even though I tried to rollback my driver.
Here's the DPC report:

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 0:15:48 (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.
Highest measured interrupt to process latency (µs): 21310.210420
Average measured interrupt to process latency (µs): 3.078407
Highest measured interrupt to DPC latency (µs): 1729.959308

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: firefox.exe
Total number of hard pagefaults 1331
Hard pagefault count of hardest hit process: 428
Highest hard pagefault resolution time (µs): 215676.082223
Total time spent in hard pagefaults (%): 0.219264
