    Random rebooting while not doing anything unusual


    Seems to have started since the last update, but not certain that's it.

    Any help? Thanks.

    When the random reboot happens, does your screen just completely go blank, and then shows your BIOS startup screen?
    ...or does Windows, all of a sudden, say that it's shutting down and restarts?

    Also, keep your smartphone nearby, and once the reboot happens, take note of the exact time HH:MM (and seconds, if possible),
    and once the computer starts up, open Event Viewer, and see if you can find anything at exactly that time, within the minute, and within seconds, or exact seconds, of the reboot, under Windows Logs in Application and System:

    Do you have a watch, or a clock, or something that tells you the time, nearby?
    Hopefully it was seconds listed as well.

    But also, after the reboot completes, go to those two sections in Event Viewer, and look at the newest entries (the newest entries will be listed first).
    Do a quick skim-through and see if you can see something that says some big error happened, or the computer restarted unusually, etc...

    In "My Computer",the Graphics Card is shown as HP 2710,which is a printer.Could you provide the Graphic Card details please.
    Also,does Reliability History have entries covering the screen blackouts and if so,what does ---view tech details ---give as the cause ?

    What I did.

    Turned off automatic restart and waited.
    One of my browsers crashed after a few hours.

    That was what was causing the reboot.

    The underlying problem was browser specific, not Win 10.

    But the automatic reboot is feecher I do not comprehend why it exists.

    Event ID: 41 Description: The system has rebooted without cleanly shutting down first. This event indicates that some unexpected activity prevented Windows from shutting down correctly. Such a shutdown might be caused by an interruption in the power supply or by a Stop error.

    Here's why Kernel Power Error 41 happens and how to fix it.

    Problem related to overheating, but proximate cause was browser activity.

    Did some tweaks and all is OK.

    That explains it. Perhaps time to clean dust from the PC, check fan settings, add more fans, better CPU cooler or reseat the CPU fan?
