[SOLVED] Computer stutters for about 3-4 seconds every few hours regardless of what i'm doing.

[HVCFOG3Y34]

Hi, I'm having an issue where my computer's audio and video stutters for 3 to 4 seconds seemingly every few hours. I don't have my own recording, but this video from 0:37 to 0:40 kind of shows what the audio sounds like. The rest of the video doesn't apply and their video is smoother than mine during the stuttering - my video matches the audio stutters. The stutters seem to happen whenever, regardless if i'm playing a game, watching a video, browsing the internet, or just sitting at my desktop.

I've made sure my drivers are updated.

Spoiler: I tried LatencyMon, but not sure what I'm looking at.

CONCLUSION
_
Your system seems to be having difficulty handling real-time audio and other tasks. You may experience drop outs, clicks or pops due to buffer underruns. One or more DPC 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 1:29:58 (h🇲🇲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): 323.20
Average measured interrupt to process latency (µs): 5.689547

Highest measured interrupt to DPC latency (µs): 319.90
Average measured interrupt to DPC latency (µs): 2.500604


_
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): 20.590
Driver with highest ISR routine execution time: HDAudBus.sys - High Definition Audio Bus Driver, Microsoft Corporation

Highest reported total ISR routine time (%): 0.000374

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): 1001.720
Driver with highest DPC routine execution time: nvlddmkm.sys - NVIDIA Windows Kernel Mode Driver, Version 511.65 , NVIDIA Corporation

DPC count (execution time 2000-4000 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.

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: nahimicsvc32.exe

Total number of hard pagefaults 50968
Hard pagefault count of hardest hit process: 19042
Number of processes hit: 83

Are you sure?
You can't get 7k r/w in native mode.
Btw.....are you clicking the reply button to answer a post?

Pretty sure. I disabled it before and stopped the samsung magician and RAPID services when I ran the last test. Unless it somehow re-enabled itself, it should have been off. When I started magician up just now, it even said something about that RAPID service is missing and to fix it I need to disable and reenable.

I'm clicking the reply button below the post I'm replying to. That last one though I must have misclicked and did a general reply by accident. The other replies where I didn't quote anyone were not directed to anyone specifically, so I didn't click reply on anyones previous posts.

I agree though that it is high. I did a CrystalDiskMark benchmark, and it's at 5674MB/s read, and 5039MB/s write.

The most likely reason UBM and CDM are showing those big numbers is rapid mode.

It may also be the reason UBM fails the testing of that disk.

I just found this thread and I'm having exactly the same issue as you described. Stutters for around 3 seconds randomly throughout the day (Once or multiple times a day).
Started happening to me around a month ago and I still didn't find what the issue is. Around a week after I upgraded my CPU and updated my BIOS

Tried fully reinstalling windows a week ago, but it didn't help.
Really hard to pinpoint the actual cause of this issue.

My specs:

• OS: Windows 11 Pro (10.0.22000)
• Motherboard: X570 AORUS ELITE
• CPU: Ryzen 5950X
• GPU: GIGABYTE RTX 3070 LHR GAMING OC
• Memory: G.SKILL TRIDENT Z NEO (2x16 GB) 3600MHz (Running only one stick because the other stick died week ago)
• Storage:
  • Samsung SSD 970 EVO Plus
  • Samsung SSD 870Q QVO
• Acessories (That where plugged for all that time)
  • Logitech G305 Lightspeed
  • Elgato Wave:3
  • Durgod keyboard

Software that might be a possible cause: (They are on 24/7)

• Argus monitor
• Wave Link
• Parsec
• Windows Terminal, running a java minecraft server
• Oculus app

that has to be rapid, a SATA ssd max speed is 550mb. RAPID is a ram drive. So explains speed.

@Serverator I would start your own thread about problem instead of adding to someone elses, it reduces confusion and its not really fair to hijack a thread

you can link to this post if it is the same.

I don't want to hijack the thread, maybe we can find the common problem. I have exactly the same problem as he described

Hi again. I replaced the failing seagate drive and still have stutters. if it matters, the seagate drive is still installed in my PC, but it's disabled so nothing can use it. Any help or ideas would be appreciated. Thanks.

take drive out if its still there

does it stutter in safe mode?
That will tell is if its a program to blame or not. I doubt it, as latency is drivers, not programs.

Do you have latest bios on motherboard? There was a problem with AMD boards but I am not sure if it extends to X470. That advice goes for both of you.

that is fine but i would still start a thread as you can get help as well.
I have same mb as you do, I had 1 weird lag spike once a week but I think it was caused by using old sound drivers, I haven't heard it this week but I don't know if that means its fixed or just had the week off. Try updating BIOS and see if that helps, its the only thing I haven't done yet.

Just took out the drive and booted into safe more. Will have to wait and see if stuttering persists. I'm starting to think it is a driver issue too.

I have the latest stable bios for my motherboard. There was a reddit post awhile back that had a beta build I could download - now it looks like they just posted the beta on the support page the 15th of this month. I haven't downloaded it because I was debating on if I should or not, I heard they can be buggy sometimes.

I'll report back if the stuttering still persists even in safe mode.

 

[HVCFOG3Y34]

It may also be the reason UBM fails the testing of that disk.

I booted into safe mode and redid a UBM benchmark. I guess the GPU is disabled or something, so it failed a benchmark test, but the all drives now finished and the 860 passed with great performance.

I saw your post on another forum about this with the TPM issue. The stuttering issue shown in a video is exactly what I have, and now that I'm thinking of it, I did enable it awhile back which might coincide when I started having the stuttering issue. I fully disabled TPM now since I don't need it as I don't use any encryption stuff or have Windows 11. I just played a game for about 4 hours today and didn't have any stuttering, which usually happens at least once in a session that long. So my issue might have been solved by turning off TPM in the bios. I'll reply back if I still experience stuttering or mark my reply as solved if in the next few days I don't have anymore stuttering.

I appreciate everyone's time and help in trying to solve my issue.

drivers don't work in safe mode.

Why did you have tpm on if you don't use win 11?

I updated to the F37c which is newest BIOS on my motherboard tonight, am hopeful it fixes the one stutter I get. After saying sound drivers may have, it happened last night. I was not amused.

 

[Roland Of Gilead]

Update your bios to the latest one. Clear CMOS (properly). This could be the stuttering introduced in earlier bios.

Figured.

I switched it on in prep from windows 11, but then decided against getting windows 11 right away, and then just left it on/forgot to turn it off until then.

That sucks... I know the pain of trying yet another fix attempt and it not working...

 

[HVCFOG3Y34]

I already have the latest official release. The newest one is a beta and I heard betas can have bugs. Is it worth it to get beta bios?

Plus, if just turning off TPM fixes it for me, I don't know if I want to mess with anything now. Still testing if it worked or not.

Yes, if it's the latest one, and tpm fixes it, then leave as is. Ye,s you are correct, the betas can be buggy. Keep an eye out for the official release of the bios.

It looks like TPM was my issue. I've played multiple hours two days now and haven't had a single stutter.

Thanks again for everyone's time and effort into helping me solve this issue.
