Windows 10: DPC latency audio problem

hey, im having dificultys with my pc. im having problem with every task im doing, even playing a yt video. so the problem is im having random freezes and audio freezes/lags every 10-40 mins. i dont exactly know whats causing it but im pretty sure its not the disks/ram. ive ran a test on a program called latencymon and thats all ive got. let me know what tests i should do to help give more information about the problem and i will. ive been having the problem for like half a year now and its pissing me off. heres a picture that might help : (bios is last version btw). also ive gotten a lag that made the pc black screen and audio loop and i had to force restart!

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 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 0:34:40 (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): 101157.70
Average measured interrupt to process latency (µs): 4.016016

Highest measured interrupt to DPC latency (µs): 441.0
Average measured interrupt to DPC latency (µs): 1.050618

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

____________________________________________________________________________________________________ _____
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): 458.200946
Driver with highest DPC routine execution time: dxgkrnl.sys - DirectX Graphics Kernel, Microsoft Corporation

____________________________________________________________________________________________________ _____
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: avastsvc.exe

Total number of hard pagefaults 1574
Hard pagefault count of hardest hit process: 867
Number of processes hit: 16

Audio stuttering/buzzing and storport.sys high dpc latency

I've only had this audio issue for a few weeks already after I did a custom windows 10 install bc of a previous problem. I've also posted twice about this but no one has helped me yet. I'll post the following possible solutions and suggestions that
I've already done to avoid repeated answers

I did: audio troubleshooter, uninstalled then reinstalled audio drivers, disabled audio enhancements and tried different audio quality under the advanced tab.


After more searching online I tried using DPC Latency Checker (and then LatencyMon to be more detailed) since I read that having high dpc latency can cause problems with real time audio among other things. Apparently
storport.sys is the problem? I literally just have basic knowledge about anything regarding this kind of stuff and I don't have any clue on how to fix this so I just hope someone can help me and give me steps by steps suggestions on how I can solve this. my
audio has just been driving me crazy with those stuttering sounds and I don't want it to worsen.

I would also like to know if having
Ricoh SD/MMC Host Controller and nothing else aside from that, under
IDE ATA/ATAPI controllers, is okay and won't cause problems?

please, I hope someone can help and answer this time around!

High DPC Latency with System Audio Through Audio Interface.

Hi,

The concern you have encountered may be due to a corrupted file or a misconfigured setting.

Many audio problems on a computer can be caused by DPC latency. DPC stands for Deferred Procedure Call. In its simplest form, it is the part of your Windows system that handles driver efficiency. If there is a driver that is taking longer than normal to
process, it may prevent other drivers from being processed in time. The worst case is that it can cause your audio interface driver from responding in time and can cause clicks, pops, distortion and dropouts.

We suggest to update the driver of your audio card. Generally speaking, updated drivers deliver better functionality and improved performance. For the most part, you certainly want to upgrade your drivers unless you have a very specific reason for not wanting
to do so. To perform the task, simply follow the steps provided by Andre Da Costa on this
link.

Should you need further assistance, feel free to get back to us.

Regards.
