    [SOLVED] sudden Windows reboot


    I had this problem developing last year that now and then Windows would suddenly reboot as if you pulled the plug on the computer briefly.
    This happened when streaming video but also happened now and then at idle.
    Aside from the potential data damage if a writing process was occurring, it was also super annoying when you were in the middle of a task and had not saved it yet.

    Searching the net for an answer became a futile attempt with the usual 5 to 7 what I call "we have no clue" steps ending typically with a clean boot or the epitome; a reinstall recommendation.

    I noticed that this occurred especially when streaming video. It could go for hours without interrupting or could happen within an hour or less. Watching a movie on a media player however was not an issue. Neither playing games.

    What is certain it is not in my case and likely in many others:
    • it's not the video card
    • it's not temperature related
    • it's not a RAM issue
    • it's not a driver issue
    • the event logs are absolutely useless
    • it is not related to Windows updates


    Soon I noticed that this only occurs when my browser Firefox (107) is running. I avoid updating Firefox because the update maniacs at Mozilla manage like little kids always to break any configuration, scripts and CSS. However, I always had earlier versions of Firefox but not the problem.

    I can confirm to you now what the problem is and where the culprit lies:

    Since I first mentioned this incident about a month ago, I'm successfully getting close without interruption to an uptime of 28 days.
    The culprit is Firefox (notwithstanding their absurd continuous "create new incompatibilities" update mania)
    Whenever you install or update Firefox (last time I did was sometime last year) the performance settings are set to the defaults which are "use recommended performance settings" and "use hardware acceleration when available".
    Therein lies the culprit.
    It appears Firefox from time to time does some kind of memory discharge or swap or something like that. That is when the sudden reboot occurs.

    Disabling in the performance section the 2 settings by unchecking them solve the problem!

    About: preferences
    Performance
    uncheck "use recommended performance settings"
    uncheck "use hardware acceleration when available"

    I have yet to find or notice a performance difference! Certain is the sudden Windows reboot has vanished.

    Others have found the same thing- and not just in FF it seems. A long time ago I must have unchecked those myself- and forgotten all about it now!

    Interesting, never came across an answer that made a reference to Firefaux being the troublemaker. Most are my own posting!
    Thanks anyway!
