Hi all, new member and have joined specifically for this particular reason. For the past 2 weeks i've been having issues with audio drop outs, stuttering and a kind of slow motion playback which sounds stuttery and is continuous and rarely goes back to normal until the PC is restarted of all internet is turned off! I never had the issue up until 2 weeks ago and i've been trying to work out what it is myself and seem to have failed miserably! I think i've narrowed it down to NDIS.SIS & TCPIP.SYS but can't find out anything else further apart from the function causing the issue being called ndisPeriodicREceivesTimer which has tons of upto 23.998239 Duration (fragmented) which seems to be the issue. I've tried updating to the latest drivers for my ethernet card & wifi adapter but both still has the same high DPC issues! Could someone please take a look at my CPU.etl file please and give me some insight on what to try next as it's driving me completely mad! Many thanks in advance.


My system specs are as follows - Crosshair V formula AM3+ mobo, FX8350 CPU, 32Gb crucial ballistix tracer, R9 290X and an ALFA AWUS036NH wifi adapter running windows 10 pro X64.


Here's the CPU.etl file - CPU


It was taken using the following command -
Code: 
[FONT=Verdana]xperf -on PROC_THREAD+LOADER+PROFILE+INTERRUPT+DPC+DRIVERS+POWER+IDLE_STATES -stackwalk Profile -BufferSize 1024 -MinBuffers 256 -MaxBuffers 256 -MaxFile 256 -FileMode Circular[/FONT]
Thanks again
 
Hi h4.... and welcome to the forums ....

Sorry for the delay in replying ... lots of old man latency!

Since the problem began so recently, one quick-fix try would be to use System Restore to go back to before the stuttering started, and to turn Windows Updates to notify and download, but not install until you allow it. If the stuttering is then gone, visit Windows Updates manually, but only install one update at a time, and test for stuttering each time. That might track down an offending update, and we can see if there's a remedy...

It sounds like you know your way around your computer, so I'm guessing you are already familiar with how to use the restore points.

If the restore doesn't work (or if System Restore was turned off .... which of course means we can't try it), can you see if you can run the SysNative info collecting app? It collects error logs and such & can hold clues for performance troubleshooting. The app was created mainly for troubleshooting BSOD problems (and the thread originates from our SysNative BSOD forum), but the info can also be useful for audio/video performance problems. The instructions mention grabbing a Performance Monitor health report (there are instructions for that as well), but be aware that for some systems - the health report runs into some issue or another, and never finishes (I'm still trying to track down the reason for that ... so far, I've only seen it on Windows 10 computers). You don't need to use Driver Verifier for now, and likely won't need the diagnostics unless you've experience higher error activity lately. If we see a big spike in errors in the error logs, we might then try a diagnostic or two. Here's the link to the thread with the info-collecting app, and all --- https://www.sysnative.com/forums/bs...windows-10-8-1-8-7-vista-post303.html#post303

Time for this old geezer to grab another cup of coffee ...

Hi OldGrayGary, thanks for getting back to me. Unfortunately I made a mistake the other week and took the easy way out and re-installed windows as it was simply easier for me as it doesn't take long to get setup so I have no restore points for that time! Another problem is that I made a new Windows 10 disk using the Microsoft tool which would have used the most upto date release with updates (I presume) so the version of Windows 10 I installed came straight off of their servers about 2 weeks ago today (Sunday) so should be pretty recent apart from a couple of updates that were available. The only new (ish) driver I remember installing was a Realtek audio driver during the fresh install and all the other stuff should have been what I usually install anyway, i've removed that driver completely though and the issue is still there. I'm quite puzzled because up until 2 weeks ago everything has been fine with Windows 10 as i've had it installed from day 1 and dropped my dual boot around 5-6 months ago because I felt no need to have it around anymore as everything was spot on in windows 10. I will try and give the SysNative tool a run and see if it'll collect anything useful although being a windows 10 system i'm not hopeful after what you mentioned!
 
Ok, I've managed to run the SysNative tool and it seemed to run to the end and finish ok, I got a rar file with it anyway so that's at least something. I also ran the perfmon/report command and got a report from that to which I was surprised about a couple of things as it mentions my CPU & GPU is rated poor (FX8350 @ 4.0Ghz & R9 290X stock!) and that my memory is very poor which I doubt as they're Crucial ballistix tactical tracer 4x8Gb sticks rated at 1600Mhz running at 1866Mhz (my issues shouldn't be memory speed related either, I checked that!), it also mentions my Disk rating is poor which shouldn't be as it's a Vertex 460a 240Gb SSD! There's definitely something fishy going on so if you could take a look for me i'd appreciate it. Here's the link to the reports - SysReport

EDIT:- By the way, I turned on all my devices again as the 1st report I made was showing errors for turned off devices.
 
Hi again ...

At long last .... I've made enough progress on some of the other threads that I should finally be able to look at yours on Wednesday ... Sorry for the delay

... and thanks for the extra files - that could help with the puzzle solving.
 
Hello H4,

Sorry for the intrusion oldGaryGary =) .

Can you please confirm if the ALFA 802.11b/g/n Wireless USB Adapter AWUS036NH Driver Utility is installed ?

Can you please post the mother board model so I can check what it`s installed with the chipset drivers.

Will Windows 10 auto-discover the device or the additional drivers are required.

If yes can you please try to install the driver only.

Hi again all

[... special thanks to Repair & Restore for helping! .... I always like a little help (I'm not getting any younger) ]

I'm guessing you disabled the wireless when troubleshooting? There does seem to be a driver stew brewing in the network drivers. The Intel 82583V Gigabit Lan's driver seems odd... can you remove it, and let Windows 10 reinstall it automatically? The ndis.sys issue has been slowing systems for a while now, I'm hoping Intel has a recent version that might fix things.

For the audio drivers, can I guess that you have both the AMD onboard audio & a Creative X-Fi card? I think the trouble might be in the audio driver mix, rather than a DPC Latency issue. For example, you have a recent Microsoft audio driver, hdaudio.sys loading and running OK, a recent AMD HD audio driver atihdwt6.sys in an error state [possibly since I believe you have the AMD HD Audio device "Disabled" in Device Manager], the digital output drivers (HD S/PDF devices) are disabled, and the Creative drivers show a mix of one 32-bit version and some 64-bit drivers....

You might remove all those audio devices & see what shows up when Windows 10 tries to sort them out. (You can always reinstall the latest full version drivers later, if you want).

Your latency trace looked pretty good, surprisingly. The highest latency during the trace was from your antivirus, Bitdefender. I noticed you have a Windows Kit installed. If it's the Windows 10 version, and you have the Windows Performance Analyzer, you can pull up this same graph using that tool. Here's a screen-shot of your DPC Latency during that trace:

Right, this will be a bit of a long post as a fair bit to get through but it does bring with it some good news! Anyway, at the beginning of last week I completely rebuilt my setup after coming into some money to do so and sold my old setup, I now own a Asus Z97 Pro Gamer with 4790K, GTX980Ti and same memory etc I had before. So, in theory being a new setup I shouldn't encounter those problems if it was an onboard component issue right? Wrong! After a few days I started to notice the stuttering again and high DPC & execution time with NDIS.sys & tcpip.sys again mainly in Youtube videos! So I checked all those drivers where up to date and if not then did so, I also turned off all power saving features in the Intel ethernet options all to no avail.
So, I hit up Google again and eventually found a post mentioning Bitdefender as being a cause with certain things on so I turned a lot of web protection stuff off etc which seemed to help Youtube play but I still had the same issues with the same drivers. So, a little further reading on an Avast site and they mentioned that the port scanning feature wasn't working properly so I went into Bitdefenders Firewall and turned off Block port scans in the network and low and behold I now have normal DPC & execution times and since starting LatencyMon about 10 minutes ago nothing has gone above 0.6ms execution time where before within 5 seconds it would shoot up into the 1.0ms+ realms!
So, information for a different product applied to a competitors in theory and i'm wondering if it might be port scan blocking from firewalls that are causing a lot of these issues? It might be worth you lads remembering my issue in the future as it may apply to a lot of other users who would likely be using anti virus software & firewalls! Anyway, thanks again for all your assistance with this matter, it's appreciated. This can now be marked as solved and I hope that it's content helps others out in the future, thanks again!

Thank you for the kind words, however the problem was not related with wifi interference at all most of them do not have any issues when the NVIDIA drivers was removed.
However I believe this will occur only with Windows 10, for some reason there are conflict between the HDMI ports, Windows 10 have something of stopping the BSOD but there is wdf01000.sys flooding as hell.
I think thus IRQ conflict and for some reason cannot get registered by the OS.

This indicates that a kernel-mode driver attempted to access pageable memory at a process IRQL that was too high. Now the question is why Windows 10 causing this?

Till now no one complain for such issues on older OS.
 
Hi again all

H4 .... very glad that the firewall tweak helped. Did I understand it right, that you turned off the portion of the firewall that blocks port scanning? [That's an unfortunate fix, if so ... since that would significantly lower our defenses ... but I suppose it could be turned off during gaming just until the firewall programs work on newer versions without the problem].

Andy ... Interesting idea about the IRQ conflict .... I figure that's worth exploring

Time for a nice big bowl of chicken soup on a chilly April evening ...
 
No problem, I thought i'd best report back what eventually worked for me, it's also been confirmed by 1 other on the Bitdefender forums as I spotted they were having a similar issue to me. It is unfortunate in a way but if your router has inbuilt port scan blocking then it doesn't really matter too much I don't think as it's already being done by another piece of equipment in the network!
 
Good point that most routers have that port-scanning blocking feature built-in. That means that your repair doesn't open a security risk after all. I like that!

Nice detective work.
