Windows 10: Slow PC, high DPC Latency, and BSOD

Hello,


I have some latency issue on my desktop, this computer should be very fast but it's not, each time I start an apps it freeze for 1sec or 2 then the apps start.

Also sometimes I have some BSOD.


My desktop configuration :

- Aorus X570 Elite firmware version F30a

- AMD Ryzen 3600X

- 16Gb of RAM 2x8Gb G.Skill F4-3200C16-8GVGB.

- 2 SSD SanDisk SSD PLUS 240GB

- RAID Controller M5015 fw 2.130.403 with 5 disks attached : 2x HitachiHDS72101 3x WDCWD1002FBYS1

- Video card Asus radeon rx 5700 xt

- 1 PCIe USB 3.1 controller card.


I done the following test with no result :

- Memory test included in Windows and the Dell 32Bit diag test

- CPU stress test with Dell 32bit diag and CPU-Z

- My disks ssd and RAID with Seagate Seatools and a CHKDSK /f on all my disk


All individual test of my hardware are ok.


My drivers are up to date I use Driver Booster, I done a test with 2 versions of the NIC drivers, with no change the log attached are the one with the newest version.

I done a fresh install of windows 10 ver 2004.


I'm a bit lost I don't understand what is not working correctly, if someone can help it would be realy appreciate.


Here some logs I hope may 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. 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 0:02:11 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: 1501,50

Average measured interrupt to process latency µs: 16,724395



Highest measured interrupt to DPC latency µs: 1498,80

Average measured interrupt to DPC latency µs: 12,812439





_________________________________________________________________________________________________________

REPORTED ISRs

_________________________________________________________________________________________________________

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

Driver with highest ISR routine execution time: ntoskrnl.exe - NT Kernel & System, Microsoft Corporation



Highest reported total ISR routine time %: 0,025699

Driver with highest ISR total time: ntoskrnl.exe - NT Kernel & System, Microsoft Corporation



Total time spent in ISRs % 0,028749



ISR count execution time <250 µs: 129788

ISR count execution time 250-500 µs: 0

ISR count execution time 500-1000 µs: 0

ISR count execution time 1000-2000 µs: 0

ISR count execution time 2000-4000 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: 6582,435539

Driver with highest DPC routine execution time: ndis.sys - NDIS Network Driver Interface Specification, Microsoft Corporation



Highest reported total DPC routine time %: 0,731182

Driver with highest DPC total execution time: Wdf01000.sys - Runtime de l’infrastructure de pilotes en mode noyau, Microsoft Corporation



Total time spent in DPCs % 1,174375



DPC count execution time <250 µs: 191570

DPC count execution time 250-500 µs: 0

DPC count execution time >=4000 µs: 2





_________________________________________________________________________________________________________

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: explorer.exe



Total number of hard pagefaults 2362

Hard pagefault count of hardest hit process: 565

Number of processes hit: 34
