    Sudden rebooting Windows 10


    Hello all,
    I'm running Windows 10, all current up to date.
    Little more than half a year ago my computer started to gradually act up from time to time by suddenly rebooting.
    Nothing much was revealed in the event viewer about it as to why, just that it rebooted unexpectedly.
    • My I7 Intel runs cool at an average of around 35 to 40C. So do the 32 GB RAM.
    • My SSD (Samsung 960 EVO NVMe) is at 77% health after 6 years with no problems reported and runs on average around 30 to 35C.
    • Testing extensively, no errors found and all are constantly monitored with hard disk Sentinel.
    • 72 hour memory scan revealed no errors.

    I the case is fairly dust free, any ventilation slots are not clogged and all has an overall good airflow.
    I did observed that it's more likely to occur when a video is streaming, so I updated the video drivers, that didn't do much.
    My video a GTX 1070 TI runs cool at around 35 to 40C as well.
    The case is very well ventilated and with rather similar constant temperatures.
    I searched for answers and solutions which seem to be a lost cause and futile repetition of listing 7 "no clue steps" all the way to reinstalling Windows 10...
    I ran SFC, I ran image health and I ran tweaking.com's Windows repair.
    All is well.
    I did notice that some motherboard monitoring apps tend to show an extreme [nonexisting] high temperature of112C on my motherboard which I cannot find with a thermal laser point metering. A phenomenon that existed since day one. Other monitoring apps (Speccy) show normal temperatures.
    I'm assuming this is an fluke in some apps misreporting/detecting.

    Recently I noticed that that the machine tends to do the sudden reboots also when idling with no activity.
    Another thing I noticed is that it sometimes appears always after about 2-3 days of uptime. often also after 4-5 days.
    yet last year in October/November I was gone for a month and the system recorded an uptime of 31 days without any interruptions.
    Last week we had 2 unusual for the time of year warm days and my system suddenly rebooted 3 times within 48 hours. once while streaming a video, once while idling and once while I was typing a letter. No temperatures anywhere in the system were higher then around 40C.
    Often suggested is the video card being the culprit but when I run imaging AI software that makes intensive use of the GPU cores everything goes flawlessly. Often the video card fans crank up to full throttle during the processing. I once peaked at 80C with no problem.

    So to eliminate any other temperature related possibilities I opened the case and placed a room fan blowing quite a bit of air into it.
    All the aforementioned average temperatures sank by about 5 to 7C.
    So far all is well and I'm up for 2 days and 17 hours.

    Could this be a temperature issue?
    Could it be that the SSD which does on occasion go to 45-50C within intense I/O be the problem?
    The SST only has a small passive heat sink. currently that external fan is also blowing quite a bit of air on it, holding the temperature around 35C.

    Anyone have any clueless insights or know something about most likely cause? searching on the Internet it seems to be quite a present issue.

    Welcome to the Forum

    Please edit your profile with ALL your hardware specs. It will help us to help you
    System Specs - Fill in at Ten Forums

    As you described and by the solution you gave and as you have it stable now, I would say it is related to temperature.
    I suggest you install a hardware monitor.
    I use OpenHardwareMonitor
    Extract to C:\Program Files (x86)\HardwareMonitor and run openhardwaremonitor.exe.
    You can configure what to see on the tray and gadget.
    It will show current, Max an min temperatures.
    Ideally, no temperature should go over 80C.

    That's one of the monitors I used/have used as it is one of them who reports is absurd non-existing temperature of 112C.

    as mentioned spot temperature metering does not show anywhere anything warmer then around 40C
    it also lists fans that don't exist as I have only 2 additional fans (fan#1 and fan#2) asides from the CPU fan at the PS fan.
    Both are running automatic regulated and are running at low speeds of around 600 to 900 RPM. Should they ever seize to work an acoustic alert would go off anyway. Those 2 fans mainly create an in-case through circulation, one pushing air into the case the other one pulling it out and have done so for at least 5 years. hence the stable and equal environmental temperatures.
    The odd thing is, that at least 3 other fans and temperatures are listed that don't exist. Neither by design, physically or otherwise.

    The problem is, it's a newer thing that started to creep up, of course typically after an update.
    It seems that a lot of folks out there have the same or similar situation, when you do a "Windows 10 suddenly reboot" search
    I even spot metered the SSD NVMe, it's pretty much, give or take a couple degrees, the same as reported by the software.
    I suspect More & more that it is an age related issue with the SSD. but no software reports any indication of such.
    Here is [an excerpt] what the system reports after a restart from a sudden reboot:
    Sudden rebooting Windows 10-evt-sys-sudden-reboot.jpg
    it takes about 90 seconds or so for the system to reboot hence the restart time off 8:29pm.
    the app EVT last entry is that 8:22 PM and then the system obviously restarts.

    The sudden reboot onset is as if one would unplug the PS for a couple seconds and then plug it back in again.
    I doubted it is a PS issue as I also run over a clean sinus stabilized output UPS and the computer is drawing less than 100 Watts.
    the PS is not even lukewarm, neither the air coming out of it rather a room temperature. I tested the machine and ran it on max load CPU, memory, video and SSD I/O more than quadrupling the power consumption and nothing happened.
    I think it is The infamous URE "unrecoverable read or write error" on the SSD...

    Does Device Manager show any flags ?
    Are there any reports in Reliability History related to the shutdown and reboot problem ?
    Have you tried ---settings>update and security>troubleshoot>additional troubleshooters ?

    1. A: NO
    2. A: Some, minor things i.e. apps stopping or not responding
    3. A: the most useless worthless feature never find anything "troubleshooter did not detect any problems"

    Is your BIOS up to date?
    As it is an old MB, is the BIOS battery still good? Use Hardware Info

    I have seen strange things when BIOS data is corrupted. The solution is to Re flash the BIOS (with new or same version).

    SOLVED "Sudden rebooting Windows 10"

    The problem in this industry (and beyond) is the heroine like addiction to updates and updating everything all the time without any user request or consent whether you want it, need it or like it. Just shoved down your throat like stuffing a goose for Foie gras!

    Turns out a Firefox default [Performance] setting was the culprit. Firefox the quite apparent industry leading "updateaholic" and constant "incompatibilitzer" master. (You know what I mean If you ever dealt with css customizations i.e. multi-row tabs, bookmark toolbar wrap etc. which get broken, messed up with every update...!)

    Somewhere in some "FireFaux" update months ago, like Windows 10 itself, a new bug or a handful thereof got "introduced".

    The Germans have a wonderful word connotation for it: "verschlimmbessern". (you can Google it) It translates approximately "by making something that is functional worse and eventually useless by constant "improving" aka updating it."
    Probably some modern perverted form of job/revenue-stream security.

    In Firefox under "Performance"
    UNCHECK "Use recommended performance settings"
    (Proclaimed as: "These settings are tailored to your computer's hardware and operating system".(Yeah right!)
    UNCHECK "Use hardware acceleration when available".
    Problem gone!
    System uptime by now over a week without any issues. Stress tested including running several [i.e. youtube] videos simultaneously.

    Mozilla broke Firefox with pointless and continues to do so with endless updates and seems unwilling or incapable to take responsibility for it. Firefox is a browser, it has one job to do. Instead, Mozilla keeps putting out more and more updates "for security purposes" while deliberately ignoring the fact that their browser is broken or they "re-brake it" with every "update"!

    No wonder that since 2018 they lost over 50 million users!!!!

    I gave/found no "solution" I merely mentioned that temperatures are all in an acceptable range.
    In the mean time however, I found the culprit. See my latest post.
    Openhardwaremonitor is junk, last update was 2020
