Bonjour tout le monde !

Aider moi a comprendre le fonctionnement de mon ordi que je vais vous présenter:
Le PC:
CPU: I7 3770K
Carte mère: Asus maximus V extrem
Ram: 16Go 1600Mhz (8Go récemment ajouter)
Carte graphique: Gigabyte Gtx 1080 G1
SSD: Kingston kc400
...

Le problèmes que je rencontre:
-Freeze audio et vidéo complètement random

Le problème arrive généralement après quelque heures d'utilisation 2/3h
Ma solution : LE REBOOT !

Solution testé qui ne fonctionne pas:
-Formatage de Windows 10
-Re-formatage et basculement a Windows 8.1
-MAJ des drivers
-Désactivation de certains périphériques
-Désactivation de certaines options dans le BIOS
-Test de la RAM / HDD / SDD & vérif si MAJ firmware RAS

Logiciel utilisé:
-Vérification de la RAM par windows (10 tests effectués)
-DPC Latency qui n'est pas 100% compatible avec Win 8.1 mais qui me trouve des pics de latence lier a mon problème (Voir photo 1)
-Et LatencyMon (je vous montre le résumer, voir photo 2,3 & la quote)

Aider moi a comprendre ce qu'il ne va pas avec mon BB

Merci de m'avoir lu , je peux tout faire dans le besoin re-re-re formater ne me fait pas peur

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 0:19:49 (h:mm:ss) on all processors.

SYSTEM INFORMATION
_________________________________________________________________________________________________________
Computer name: ****
OS version: Windows 8.1 , 6.2, build: 9200 (x64)
Hardware: ASUSTeK COMPUTER INC., MAXIMUS V EXTREME
CPU: GenuineIntel Intel(R) Core(TM) i7-3770K CPU @ 3.50GHz
Logical processors: 8
Processor groups: 1
RAM: 16324 MB total


_________________________________________________________________________________________________________
CPU SPEED
_________________________________________________________________________________________________________
Reported CPU speed: 350 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): 28074,678956
Average measured interrupt to process latency (µs): 4,588713

Highest measured interrupt to DPC latency (µs): 28071,460691
Average measured interrupt to DPC latency (µs): 1,149173


_________________________________________________________________________________________________________
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): 240,555714
Driver with highest ISR routine execution time: dxgkrnl.sys - DirectX Graphics Kernel, Microsoft Corporation

Highest reported total ISR routine time (%): 0,215794
Driver with highest ISR total time: dxgkrnl.sys - DirectX Graphics Kernel, Microsoft Corporation

Total time spent in ISRs (%) 0,282776

ISR count (execution time <250 µs): 2193703
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): 26656,100571
Driver with highest DPC routine execution time: em008_64.dat

Highest reported total DPC routine time (%): 0,191301
Driver with highest DPC total execution time: USBPORT.SYS - Pilote de port USB 1.1 & 2.0, Microsoft Corporation

Total time spent in DPCs (%) 0,498066

DPC count (execution time <250 µs): 9691777
DPC count (execution time 250-500 µs): 0
DPC count (execution time 500-999 µs): 3
DPC count (execution time 1000-1999 µs): 1
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.


Process with highest pagefault count: chrome.exe

Total number of hard pagefaults 200
Hard pagefault count of hardest hit process: 91
Highest hard pagefault resolution time (µs): 913,445143
Total time spent in hard pagefaults (%): 0,000316
Number of processes hit: 7
