    Mouse Stutters, Sound Tears, Performance Drops

    Hello everybody,
    What my system is:
    Acer VN7-791G Gaming Notebook
    Intel Core i5 4210H
    GTX 860M 2GB
    8GB 1600 MHz DDR3
    750GB 5400RPM SATA

    What my problems are:

    - 10-20 minutes after I start up my PC, my mouse cursor starts stuttering. It just teleports from place to place, or just plain freezes. Touchpad does the same thing. Also, it doesn't matter if I'm just browsing or running an app.

    - During this "stutter phase", as I call it, if I'm watching or playing anything I hear very loud sound tears from the lap top. These tears stop as soon as I take my hands off the mouse.

    - Also during this phase: If I'm playing a game, my frame rate drops to unplayable levels when I'm touching the mouse, it reverts back to perfect fps as soon as I stop messing with the mouse. Same thing happen with videos, they slow down and cause disgusting sound tears when I touch the mouse, and revert back to normal after I leave it alone.

    What I have tried:
    - Updated my chipset drivers.
    - Updated my GPU drives.
    - Updated my mouse drivers.
    - Switched mouses.
    - Ran a disk scan using cmd.
    - Closed a bunch of unnecessary programs and tasks during gaming.
    - Set Windows Updates to manual for some reason.
    - Found out that nVidia ShadowPlay was marked "running" and closed it.
    - Shut my anti-virus programs down.

    Heat under load is at acceptable levels. I'm also using a cooling pad.

    The problem started a few days ago, all of a sudden, leading me to believe that it was caused by a Windows Update, or a bad driver, I am just unable to pinpoint it.

    Please help. Thank you.

    I've been having the exact same problem since like two days ago, also when my Windows updated. I really need a fix for this because I have to use a mouse for audio editing and gaming and this is driving me insane. Please help

    I'm having the same issue. I've been trying everything I can think of and nothing has worked for me yet. I'm an animator so I need to be able to have functioning audio and video and this is incredibly frustrating. I've now turned off auto-updates because of this.

    I have an HP Envy All-in-One that I got maybe six months ago? Haven't had a single issue with it until this update.

    I tried uninstalling the last update but it didn't solve anything, this is awful, I can't work with a mouse malfunction like this.

    I decided to just do a system restore to before any of these updates. It fixed the mouse issue but now the computer start up is incredibly slow and takes a few tries to even properly start. This is the worst OS I've ever had the displeasure of using.

    This sound like the same problem as many others are having, it is caused by an update from Intel, after they updated "Intel(r) Technology Access - Service" around the 10th this month, these mouse lags and sound problems started for many.

    To temp fix it you can disable this service, or stop it from the task manager (but then you would have to do it each boot).

    Here is a couple other threads about this issue:
    Drop in performance/ mouse stuttering after about 20 min
    Laptop clogs up when idle, full RAM and wierd CPU spikes

    Interesting ive just done a post cause my keyboard wont work on powerup till I do a restart. But Ive noticed the mouse is also now really jerky too. I stepped back to remove the Intel(R) Technology Access load on 14/3/2015 but had a lot of windows errors so my PC didnt like that roll back. Just living with this at the moment hoping a clever person realises there are a few issues with this new update.

    One cause could be a driver problem. Run this program and see if you have red bars. If yes, you need to check all drivers.

    Try what Knector said. Had the same problems 2-3 days ago and it is true that Interl(r) Tech. Access is the culprit. You can do as he says but it will require that you apply the quick fix every reboot. You can instead opt to disable the service related to the driver by typing services.msc in the run panel then searching for Intel(r) Technology Access and disabling it during startup. If there's also a problem regarding your network connection which happened in my case, check the current default network adapter your notebook is using and make sure you're using only one and not the intel(r) tech access.

    So yesterday I went into task manager (processes) and found Intel (R) Technology Access (click on name to put in alphabetical order if that helps) and i ended the application. Mouse immediate ok. Today I find that it has stayed off (looked in services says stopped which is good news at present as PC is working fine. Keyboard good mouse good Disc not at 100% CPU back under 10% so that will do until hopefully intel do a patch.
