[SOLVED] DPC ISSUE, micro stuttering

[Calcifer]

Hi again

I'm not sure how accurate the Latency Monitor results are, since the program hasn't been updated since Windows 7. You can try creating a cpu trace with Windows 10's Performance Monitor ... hopefully that would work (though since it had trouble creating the health report, it's not certain).

Did we check your Virtual Memory settings yet? If it is currently set to have Windows 10 automatically adjust things, try setting the range manually, and see if there's any effect. Since you have 8 GB of system memory, a reasonable range would be 8192 MB for the lower setting and 16384 for the higher setting.

See if you can get the SysNative info collector to run - you can try it with administrative rights, and if that doesn't help, in Safe Mode (also with administrative rights).

Make sure that Latency Monitor isn't running when you are testing for the audio/visual effects: Latency Monitor itself can show rather high latency.

And ... one of the things you still have the option of trying: make a system image backup, and then go back to Windows 7. If everything runs well in Windows 7, it just might be that the Windows 7 drivers work better for your hardware/software mix. You could still upgrade your Windows 7 to Windows 10 again until July 29th of this year. You could make a system image of your Windows 7 then, too, if it is working well -- in case Windows 10 just doesn't behave itself either now or on a future upgrade try.

I've had to move some of my customers computers back to Windows 7 - but most of those were at least six or seven years old, and were borderline compatible for Windows 10. Windows 7 will still continue to get security updates until mid-January of 2020.

Let us know how things go. If you want to keep working on getting Windows 10 to a non-stuttering state, our next step is to get the info-collection app to run. There might be a clue in there.... and try a Performance Monitor cpu trace.

Hope for the best!

hi again.
first of all thank you again for keep replying me.

i'll try everything you just said.

in the meanwhile i uninstalled audio driver and i put the audio card on disabled. i left latecy mon ON and i let the computer in idle during dinner.

here the report :

and here the screenshots






i'm starting to think that is a nvidia driver issue. i'll tel you know new update after i will follow your advices.


thank you again.

 

[OldGrayGary]

Hi again

See if you can change those Virtual Memory settings ... and test if that helps. Does the drive with the page file have plenty of room? Even in Latency Monitor's results, the latencies aren't horrific, but the page file usage is high. Maybe we'll find something in your error logs.

 

[Calcifer]

at the moment I figured out to how make work the sysnative app. i just created a desktop and documents folders in user folder on C:
now i'm waiting i don't know what because it keeps saying Waiting for SystemInfo. i don't know if i can do anything in the meanwhile. by the way it started with audio driver uninstalled and device disabled, could it be a problem ?

 

[Calcifer]

ok after 1 hour i closed it... always Waiting for SystemInfo

here's the zipped file

Microsoft services

 

[OldGrayGary]

Hm... sounds like the app might have problems with relocated user folders? (I'll have to check with the author to see ...) ... are you running the app as administrator? and have you tried in Safe Mode yet? (if the issue is folder locations, it might not help ...)

I don't think the status of an audio driver would bother the app.

I'll have a look at what it came up with so far.

 

[OldGrayGary]

Hi ... just unzipped the archive, and it looks like much of the logs made it OK ... I'll guess the long time involved capturing the System Information app data would be if your error logs were large ... I imagine it can take quite a while with a large amount of errors. One user last week had to let the app run for several hours... the error logs had a rather amazing amount of errors..... Let's hope we'll find a clue in there...

 

[Calcifer]

so i have to re do it untill it automatically close ?

 

[OldGrayGary]

It might finish eventually.... (might/might not) ... on some systems, there are so many errors that it takes a good long while to pack them all in a file .... But there are other things that can cause the collection trouble...

I'm interested to hear if things improve after the Virtual Memory settings are set .... Let us know if the page file is on a drive that doesn't have a lot of free space, too ....

Time for sleep! I should have time to check back tomorrow evening....

hi again. hehe i suppose we have different time zones :)

here's how is set now the virtual memory




and here the drive space situation




C drive is the SSD where i have installed just the OS and drivers.

D drive is the HDD where i have all the softwares, musics, pictures, games, documents and also the desktop

this as i said is to prevent write process on the SSD in order to don't decrease its lifespan.
about that i've read that on the SSD the virtual memory shouldn't be touch or even moved on the hdd to avoid the risk to reduce its lifespan.

i'm just a bit worried about this. i've read a lot of different and opposing opinion but if you tell me that nothing happen i'll do it.

thank you , once again :)

 

[OldGrayGary]

Hi again

Sorry for the delay... (busier lately...)

I've been looking through the files (thank you for posting them) ... and there are a lot of errors for a fairly new system. Your Avira antivirus program had a lot of error between March 3rd and 8th, SkyDrive (OneDrive) is complaining about not being set up, some Plug-and-Play devices weren't finding drivers to run them, your DHCP Client Service wasn't running - causing Network Location Awareness to fail, Windows Updates have been failing in the background since November (which is why you are still stuck on an older build), and some Softonic downloads conflicted with the components in your WinSxs folder.....

Bit of a mess. What would I do?....

You've been fighting this for at least four months. I'd say it's time to start over. Your networking isn't working like it should, and your audio devices aren't either. Somehow you even ended up with 2011 drivers for some of your Intel chipset components. There are some newer Intel chipset drivers (2016) that might help ... and should be found and install automatically if you do a fresh install. And by fresh install, I mean a clean install. And this time... do not add any drivers on your own, but let Windows 10 install what it has (it has a fairly extensive collection). Do not use utilities like DriverMax, or any KMS software. Save your product license keys for Windows and Office ahead-of-time, and don't install Office until after you've clean installed Windows 10 & it has grabbed all the latest updates. Let Windows Defender run your protection for the first hours, while you update things (don't install Avira yet). Then install Office. Visit Windows Updates manually a few times after installing Office, because there will be some updates to install. When Windows & Office have finished updating (keep updating manually until "Check for updates" reports no updates to install), then you can install Avira. After Avira has installed, check that Windows Defender has been disabled. Avira should disable Windows Defender automatically when Avira is installing - but check anyway. If Windows Defender has not been disabled, use Group Policy to disable it. You only want one antivirus program running. Let Avira scan your Internet traffic - its a must these days (you had its network scanner turned off).

After Windows, Office, & Avira are installed and updating without errors: check EventViewer to make sure there are no serious errors listed. Investigate as many as you can (post here if any Critical Errors show up, or if there are errors in the Error list that you don't know how to fix).

Then install your games - one at a time. And test for audio trouble. If necessary, disable the nVidia HD audio again - using the same steps as last time. The worst offender (the game that produced the most errors) was Unreal Engine 4. That game was one cranky game - I'm guessing it produced errors every time you played it. Install that one last, if at all. And check on the Unreal Engine website to see if there are any patches or updates that help it get along with Windows 10.

I double-checked on the Virtual Memory and page file situation, and it seems that your setup should be OK with Windows and the page file on the SSD. Since you have the 120 GB SSD, that should be enough room. I think it might be interesting to set the Virtual Memory range manually, even though you have an SSD, because games are notorious offenders when it comes to memory leaks and such -- which can to page file madness (page file gets huge in a hurry & cramps your style). Since you've got all that space, it shouldn't hurt to have the large range set.

The length of SSD lifespans is rather an unknown ... something like how the actual lifespan of DVDs is hard to predict (because they haven't been around long enough to know for certain). The expectations are pretty good for decent lifespans for the SSDs. I do recommend a good backup plan, because when SSDs fail, they tend to fail suddenly and spectacularly - often with complete and final loss of all data on the drive. Since the prices for SSDs have dropped a lot, that makes it a bit less painful to replace them.

I think the whole clean install could be done in a day (weekend day, anyways) or two. That sounds better than struggling for another month or so.
What do you think?

 

[OldGrayGary]

P.S. ... I'm getting older, I always forget something.

Somehow, on your last system: you had "Intel Smart Connect Technology" installed. Please do not install it on Windows 10. It is not compatible with Windows 10 (and has been discontinued). It might have been installed if you used old drivers for your gaming devices (usb, audio, keyboard, mouse). Try not to use any old programs or drivers for those devices until after you have tested that Windows 10 runs everything without stuttering or errors. Then - if you must - check if newer Windows 10 compatible apps are available for your gaming/audio devices.

 

[OldGrayGary]

one more P.S. ...

By the way .... fan of "Howl's Moving Castle" & Studio Ghibli?

 

[Calcifer]

hi again ! thank you very much for answering me :)

wow, a lot of homework !

i'll do that on weekend due to work.

SkyDrive (OneDrive) is complaining about not being set up

since i don't use it, avoid to install it the next time will solve this then ? or do you advice to fully set it ?

your DHCP Client Service wasn't running - causing Network Location Awareness to fail

what could be the issue that cause it ? just to don't risk to do something that re introduce this issue.

Windows Updates have been failing in the background since November (which is why you are still stuck on an older build)

i always checked if there were update available and it always said no, i don't know why.

Somehow you even ended up with 2011 drivers for some of your Intel chipset components. There are some newer Intel chipset drivers (2016) that might help ... and should be found and install automatically if you do a fresh install. And by fresh install, I mean a clean install. And this time... do not add any drivers on your own, but let Windows 10 install what it has (it has a fairly extensive collection).

so this time i won't install chipset driver from asrock website and i'll wait windows since it should do it automatically. right ? what do you advice about asus xonar dgx sound card drivers ?

I double-checked on the Virtual Memory and page file situation, and it seems that your setup should be OK with Windows and the page file on the SSD. Since you have the 120 GB SSD, that should be enough room. I think it might be interesting to set the Virtual Memory range manually, even though you have an SSD, because games are notorious offenders when it comes to memory leaks and such -- which can to page file madness (page file gets huge in a hurry & cramps your style). Since you've got all that space, it shouldn't hurt to have the large range set.

I do recommend a good backup plan, because when SSDs fail, they tend to fail suddenly and spectacularly - often with complete and final loss of all data on the drive. Since the prices for SSDs have dropped a lot, that makes it a bit less painful to replace them.

so do you advice to do it anyway after another fresh install ?

Somehow, on your last system: you had "Intel Smart Connect Technology" installed. Please do not install it on Windows 10. It is not compatible with Windows 10 (and has been discontinued). It might have been installed if you used old drivers for your gaming devices (usb, audio, keyboard, mouse).

strange, i disabled it through UEFI. by the way, should i avoid to install intel rapid storage as well ? and if yes , disable it through UEFI as well ?

What do you think?

I THINK YOU ARE GREAT ! :)

By the way .... fan of "Howl's Moving Castle" & Studio Ghibli?

YES !! i loved the movie ( like all the others of the studio ghibli ). my wife adviced me to read the book as well and when i did it i found it really great ! Calcifer is my favorite character so far. though i imagined it like the movie since i liked it more than the book rappresentation. the book story is better in my honest opinion.


thank you, once again !

Hi again

Thank you for the kind words ... but you know, I'm an old Grump! :) (appreciated)

Calcifer - I think you'll be best off with the step-by-step approach (you can print that last post if you'd like). It will help you narrow down any source of trouble that might surprise us. By not using older drivers from downloads, you can give Windows 10 the chance to use it's own library of drivers -- usually provided by the vendors that made your hardware. Later on, if something seems "left out" ... we can discuss the options.

The way you had the page file setup was fine (it was on the same drive as Windows ...the SSD). I do like the idea of a set range for Virtual Memory (8192 MB for the lower setting and 16384 for the higher setting) .... it's nice and generous, and allows a misbehaving game with a memory leak to not kill your system right away.

I'm not all the well-versed in all the UEFI options ... I'll have to check on the Smart Connect options. I expect that it is probably best left disabled (since it has been discontinued). I'm hoping the old Smart Connect driver won't get installed onto your new installation, since we'll be avoiding the older drivers.

The Windows Update issue was one of the main reasons I advised the fresh start. I believe the background tasks were having issues, so Windows Update wasn't able to connect (it didn't know that there were newer updates, because it never reached the Microsoft site).

Regarding OneDrive, it is built-in to Windows 10, but you don't have to use it. When the time comes, visit the Microsoft site with the instructions on how to turn it off permanently. If you have any questions about it, let us know.
Turn off or uninstall OneDrive - OneDrive

You might be able to find those instructions in Italian, if you have a local Microsoft site (or use Google Translate to translate the page from English)

Ciao :)

P.S. .... Almost everyone in my family is a big fan of Studio Ghibli and their work ... so amazing, what's not to like? My oldest daughter's favorite is Howl (though they are almost all favorites) ... I liked Kiki when my kids were little, and I thought "The Wind Rises" was a wonderful farewell ... like a visual symphony!

hi again !
sorry to bother you again but it's just to be sure i won't do anything wrong this time. i'll let windows install everything automatically but also for not integrated hardware ? i mean graphic card and audio card drivers.

for the intel rapid storage, if i don't install the software, i'm pretty sure that the Link Power Management will be active and i cannot disbale it without installing its driver and so the relative software within. do you advice to keep it and download and install it or disable it through UEFI like i did for the Intel Smart Connect Technology ?

about avira, you said i have network scanner turned off. i searched it also on the web but i can't find the option . do you know where i can check it on the new install to see if i have it enabled ?


for the rest, i got it ! :)
i'll follow step by step all what you said.


ciao :) and thank you again.

p.s. i loved a lot of the studio ghibli also the Princess Mononoke, Spirited Away, Totoro and Nausicaa of the valley of the wind. wy wife even gifted me the book of spirited away but i didn't read it yet. i still have to see "the wind rises" !

 

[OldGrayGary]

Hi again

I think it would be good to try with things on default settings (let Windows install the drivers it finds on its own from its collection ... there are likely to be drivers for most - if not all - of your devices). Power Link Management seems like a reasonable idea if it works - why not leave it enabled & see if everything works OK with it. If it behaves badly, we'll change it.

I would test your favorite games with just the plain vanilla drivers that Windows 10 installs as a first try. Then, if no audio stuttering is heard, try another game. Continue testing, and if the quality of sound & video are fine with the basic driver installation ... it might be OK to dodge troubles from the fancier drivers. We won't know until a little time has gone by.
_______________

I won't give away any "spoilers" for "The Wind Rises" - other than to say it is as beautiful as we'd expect from Studio Ghibli. If you don't see it in a theater, make sure you've a good screen & nice sound. [and... from "Spirited Away" - my daughters really liked the dragon character]

Let's hope that if Windows 10 "breathes fire" in your new installation ... it will be because it is so fast, it's like lightning!

 

[OldGrayGary]

Oh, sorry, I forgot something .... [I imagine no one will be surprised by this]

Regarding Avira Antivirus: I noticed you had a version of Avira 2016 installed. If it is the "Pro" version, it will have more active components than the free version.

Here's an idea of what the free Avira looks like:


And here is an idea of what the "Pro" version looks like:


If you have the "Pro" version, you can enable the "Web" (which scans your Internet traffic) and the "Mail" (which scans your email). If not, then don't worry about it.

 

[RepairandRestore]

strange, i disabled it through UEFI. by the way, should i avoid to install intel rapid storage as well ? and if yes , disable it through UEFI as well ?

Actually there are some vendors locking the EFI, the option claim this feature is off but this is not completely true.

To be honest the problem occur on branded laptops mainly.

Installing the Windows 10 on MBR cause total chaos, broken services, network unavailable, BSOD and many many more fun things you can troubleshoot to the end of the world.

I always advice the new users of Windows 10 to reinstall fresh copy of Windows 10 as this will format the HDD to GPT. This problems is caused of the new licenses services of Microsoft as they registering the licenses on hardware ID. The safest way they can achieve that is to check the EFI for previous build and confirm this is genuine copy.

The problem now is if you decided to make a fresh install of Windows 10, you will need a product key for activating your windows, Microsoft claimed you can use your old Windows product key of 7 or 8 without enterprise edition during installation. Well that is not completely true as till now I`ve try this few times and never work-it out for me. There are guide with random not-working windows 10 keys to at least download the correct build for your license, even than you will be unable to register your product without calling Microsoft Support.

This is really bizarre Microsoft policy but unfortunately this causing a lot of problems recently.

OldGAryGary could we summaries the recent DPC ISSUES and go for a complete guide and recommendations?

Let's hope that if Windows 10 "breathes fire" in your new installation ... it will be because it is so fast, it's like lightning!

hi again !
just finished fresh install. i didn't install anything at all yet.
here's the device manager screenshot :




as you can see unfortunately the audio card driver hasn't been installed . furthermore i see a different icon on some device such as graphic card and controller devices. do you know what does it mean ? i have checked if they are the last Windows driver and it says they are. Windows is also up to date.

about avira , yes i have the free version.

what do you advice to do ? because now the only audio i have is through hdmi on monitor.


thank you again for your kind help :)

p.s. the dragon character from "Spirited Away" is haku and i found it amazing too !
