    PC lagging and stuttering during network traffic (Win 10)


    So I'm at my wits end on this one. I've searched high and low on just about every forum for a fix to this.

    My PC seems to stutter and lag during any kind of network traffic to my PC. At first I thought it was just happening when I was watching Youtube vids or downloading torrents but sitting there with nothing running and a simple message through skype will trigger it too. Just did a re-install of windows and it's still happening, which is making me lose my mind.
    Restarting Windows fixes it temporarily but within 1-2 hours the problem begins coming back, it's small at first but gets increadibly bad later. Leaving my pc running all night, by next morning watching youtube vids is pretty much in slow motion with long drawn out stuttery sound.
    Disabling the wireless adaptor actually stops it all, I can start watching a youtube vid and halfway through it lagging and sputtering along if I disable the adaptor it instantly plays normal, until it gets through everything it buffered.

    Heres a breakdown of everything I've tried thus far to fix it.

    -Updated Windows
    -Updated graphics driver
    -Updated sound driver
    -Updated wireless drivers
    -Disabled wifi card and used a USB adaptor instead
    -Disabled my page file
    -Disabled event log
    -Tried a different browser
    -Restarting modem

    and finally the last thing I tried:
    -Re-installed Windows 10 as a fresh install on a brand new SSD

    There may have been a few other things I tried to in there but cannot remember.
    If anyone has had something similar or additional steps I can try please help me, this thing is driving me insane.

    Hi Vedegris and welcome to Ten Forums!

    Since you've done so much work already, possibility to solve your problem here looks not very high to me.
    First of all - I have no idea, but if I would be in your place there are few things that I would do: when the problem occurs
    - check in task manager (or ProcessExplorer from Sysinternals) if there is CPU high load and which program causes it,
    - do the same for possible memory leak
    - try with wired network
    - reset you BIOS

    I'm sure you've done all the search for possible problems of your motherboard and graphic card.

    Thanks for your input so far, I'll give them all a crack, need to get a longer cable to try wired but will def give it a go.

    I have noticed the "System and Compressed Memory" process seems to spike when it starts lagging but never more than about 10-15%, everything else looks fine, CPU usage and memory doesn't top out at all, just that one process seems to be affected.

    Will update once I've tried some of your solutions.

    I thought i am loosing my mind, but i have the same problem. First i thought is a Laptop fault, but yesterday i digged bigger, and i noticed first it was when i used torrent. Tried to install other versions and nothing happened. Then i realised it was when i have any download traffic. Started youtube in 240p and when i make a bandwidth test everything get slow. I get frammed in 240p on a Thinkpad t440p with i5 4300M, 8GB of 1600 RAM and 180 intel 530 SSD.

    Yesterday i reinstalled all the drivers, problem was solved for a few hours, and it begun again at midnight. Tried to make a windows 10 clean install, but nothing solved it. Please keep me updated as i don't know what else to do.

    I use windows 10 pro edition and the laptop is not that low spec

    Check, if you still have drivers that you reinstalled. Windows may overwrite them. If so, that can be possible solution, since you can block new driver installation. Descriptions are here in Ten Forums.

    Hi, can you specify your Wifi card, and whether you previously were able to use Win 10 ok, and this suddenly started happening, or whether it's been a problem all the time since you've had Win 10 installed.

    Have you checked for Win 10 compatibility?

    Latency issues related to drivers seem a common cause of stuttering.
    You might learn more by using LatencyMon (free by Resplendence) and posting a screenshot.
    This may help to indicate which driver it's related to.

    Further, you could try the driver that worked in a previous edition of Windows, if you were previously running, say, Win 8 on it.
    But as noted above, you'd have to make sure it wasn't overwritten by Windows, which will replace any driver (older or newer) different to what Uncle MS thinks good for you.

    If you search the forum for 'stutter' you will find a good number of threads on the topic. Please have a look to see if one helps you.

    I know is not my topic and i apologize, but sincer i have the same problem, i will post a picture with the LatencyMon. I made the test while watching an youtube video and making a bandwith test on speedtest.

    Checked the wireless driver, is still the one i reinstalled and worked fine. The card is an Intel Dual Band Wireless AC-7260 and the driver is still 18.33.0.2, which is the last one. Can't tell if on another system worked, as i just bought the laptop, and i installed windows 10, but for the first month worked like a charm. Yesterday i also installed some things that said were critical on lenovo driver page: Intel Management Engine Component, Intel Collaborative Processor Performance Control, Lenovo quick optimizer, and Lenovo Battery Gauge, but the problem is going on for at least 3-4 weeks.

    Update: The PC is lagging even if i play video from local ssd, not only from youtube, whenever i make a high network traffic. The pc is killed at a simple bandwith test, at speeds of about 140 mbs

    Hi, you will learn more from the report (apologies if you already know this) if
    a. You read this page
    http://www.resplendence.com/latencymon_using

    "Report view

    The report view displays a conclusion of the suitability of your system for playing real-time audio at the top. If the execution times of all DPC and ISR routines stay below 2000 µs (microseconds), your system is considered suitable for handling real-time audio without dropouts. If some routines have execution times between 2000 µs and 4000 µs, your system is considered doubtful. If ISR or DPC routines are detected to execute for longer than 4000 µs, a system is considered unsuitable for handling real-time audio. Note that these numbers are just chosen arbitrarily. For optimal midi to audio latencies, buffer sizes of a sound card and driver should be set to very low values then only very low execution times of DPCs and ISRs become acceptable. "

    b. also look at the Stats and Drivers tabs

    By comparison here's mine (you can see my specs- a modest modern CPU...)

    I've been having this same problem as well, on a Lenovo Yoga 2 Pro with Intel Wireless AC 7260. But I found a few similar threads, which included a solution related to Bitdefender, and it worked for me too! So now I'm wondering how many of you are also running Bitdefender (or possibly another antivirus solution with similar features).

    Here's what seems to have solved it for me: Within Bitdefender 2016, click the down arrow to view the Modules, choose the Firewall section, and turn off "Block port scans in the network".
