Hello,
recently I've updated my PC with:
MSI B450-A PRO MAX
AMD RYZEN 5 3600 Socket AM4 3,6-4,2 Ghz
MSI GeForce RTX 2060 SUPER GAMING X
Crucial DDR4 Ballistix 16GB 2x8 3000 15
plus few older parts:
SSD Crucial BX100 250GB SATA3
Seagate Barracuda 1TB 3.5" SATA III
Thermaltake Smart SE 530W
obudowa Zalman R1
From the vary beginning I'm having issues while playing games or watching movies. There happens irregular freezes, FPS drops while audio is crackling, buzzing. Firtly I've though its overheating problem, so I installed Fortis 3 cooler (It reduced temp from 95 to 75 Celsius, 203F to 167F) but the issue doesn't go away. Then I started tests with LatencyMon and it shows that right after fps drop latency is too high:

Here is test without playing:

And here without playing and while GPU is shut down in device manager:

Here is log from first test:

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. 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 1:43:06 (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): 101115,60
Average measured interrupt to process latency (µs): 4,810918
Highest measured interrupt to DPC latency (µs): 101112,50
Average measured interrupt to DPC latency (µs): 1,876497

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: cavwp.exe
Total number of hard pagefaults 134681
Hard pagefault count of hardest hit process: 21854
Number of processes hit: 148

Storport.sys and dxfkrnl.sys are the main issues. I've tried to find solution through internet by so far nothing helped. What i did:
- change GPU options to high performance
- BIOS update
- Ram test with Memtest86
- uninstall and install new drivers for chipset, mobo and gpu
- shut down "High Precision Event Timer"
- uninstall realtek HD audio driver
I don't know what to do
Maybe should I do fresh windows installation?
Maybe its a hardware problem? How can i check if there is something something with GPU, CPU or motherboard? Or maybe something to do in Bios with voltages?
Please help me, I'm losing my mind
And sorry for ma English, I don't use it much often.
Edit. I'm sorry for wrong section. I was meaning to post in Windows 10.
