    And another high DPC/sound issue thread

    Hi,

    New here and coming with the usual combination of what seems to be high DPC/sound stuttering in Windows 7 x64.

    It's been happening basically since the beginning and usually after having the PC running for a while. If I restart it takes a while until it creeps back up. I have all drivers up to date as far as I know and having installed one or another didn't make any difference.

    Run LatencyMon and xperf and the main culprits seem to be the network processes (netbt.sys, ndis.sys and tcpip.sys) and iusb3xhc.sys. I have tried disabling the Ethernet and anything related to NDIS, since it's usually the highest one, but still peaking. Also disabled the Wi-Fi miniport adapters but still the same.

    I have a Toshiba Satellite with these specs:

    OS: Windows 7, x64
    Processor: Intel i7-3610QM @ 2.30GHz
    RAM: 16GB
    Sound: Onboard Realtek
    Video: NVIDIA GeForce GT 630M

    Any help would be most welcome because it drives me insane having to drop everything and restart to get it back to normal.

    Cheers!

    Hello and Welcome to Sysnative!

    To enable us to get a decent handle on your PC, can you supply a screenshot of LatencyMon showing Total execution times? Also carefully read and follow the BSOD Sticky and attach the required zipped folder, it'll give us a tonne of very useful background info: http://www.sysnative.com/forums/bsod...8-7-vista.html

    Sorry for the delay to come back. Very busy days...

    Here's the LatencyMon capture: http://img801.imageshack.us/img801/6572/fqly.jpg

    And the zip file is attached.

    It wasn't a very long analysis but up there you have the 3 usual suspects giving spikes. Any help would be more than welcome.

    Cheers!

    Re: And another high DPC/sound issue thread

    Hello Andunemir,

    Could you please also run Windows SDK setup and select to install "Windows Performance Toolkit"? Once it's installed run the following command from elevated (Run As Administrator) command prompt (if the command asks you to modify the registry, please do that, reboot your computer and re-run the command):

    Code:
    xperf -on PROC_THREAD+LOADER+PROFILE+INTERRUPT+DPC+DRIVERS -stackwalk Profile -BufferSize 1024 -MinBuffers 256 -MaxBuffers 256 -MaxFile 256 -FileMode Circular
    Now, play some audio until you experience the issues you mentioned. Once you do, run the following command to stop the logging:

    Code:
    xperf -stop -d C:\CPU.etl
    Attach the C:\CPU.etl log file here.

    Thanks.

    Thanks for the reply. File too big to attach it here so I've uploaded it on Mediafire: CPU

    Re: And another high DPC/sound issue thread

    Thanks for the report.

    The issues seems to be caused by AVG TDI Driver (avgtdia.sys):

    You could try removing AVG products temporary to see if the issues resolve. Please let me know the results afterwards.

    I've updated my wi-fi driver that, as it happens, was out of date regardless of what Toshiba said. If the issue continues then I'll go for AVG and see what happens.

    Thanks for the help. I'll report back.

    Re: And another high DPC/sound issue thread

    The update didn't work but uninstalling AVG did. Well spotted, man. I had tried stopping it before because I had read somewhere it did cause conflicts but because that didn't fix it I stopped considering. So far 2 days with the PC running and not a single sign of trouble.

    Thanks for your help. I'll report back if it was to come back.
