노트북을 새로 샀는데  얘가 비정기적으로  또 상당히 많이 프리징 됩니다. os 재설치는 수십번 해봤고  서비스 센터도 몇번 들어갔다 왓는데 os설치 문제라고만 하는데  답답하네요   이런저런거 알아보다가 latencymon 이란걸 보고 돌려봤는데 리포팅 결과는 아래와 같습니다.  혹 어떤문제가 보이는지 봐주실수 있는분 계신가요

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  0:14:08  (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):   5428.931837
Average measured interrupt to process latency (µs):   4.238020

Highest measured interrupt to DPC latency (µs):       5425.771347
Average measured interrupt to DPC latency (µs):       1.531113

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:                 chrome.exe

Total number of hard pagefaults                       2577
