    Instant reboot


    Once again I got an instant reboot; that is, I am using my computer without doing anything in particular (sometimes I am not even at my computer) and the screen goes black and a few moments later I see that the computer is booting up. The Windows 10 installation is set to blue screen instead of reboot.

    This is so annoying due to lack of information about the problem. This has been happening since the middle of July, 2019 (when I bought the computer). I have attached some of the System Event Log around the event.

    Please upload a new V2.
    (V2 and DM each collect event logs.

    Ah, sorry I didn't think of that. I did assume that it must collect that data. I've used the computer for 8ish hours since the instant reboot. If that has made the data less than ideal, I can upload the V2 log after the next time it happens. Note that the computer is the same one; I just renamed it.

    The logs from dates 3/4 to 3/6 displayed 1 unexpected shutdown and restart.
    These entries in the event viewer can be seen when there are BSOD, temperature problems, malfunctioning hardware, and with manual power offs.

    If they become more frequent then place the computer into safe mode:
    Boot into Safe Mode on Windows 10

    Report into the thread whether there are or are not unexpected shutdowns and restart while in safe mode.

    Code:
    Event[325]:
      Log Name: System

      Date: 2020-03-05T21:13:18.872

      Description: 
    The system has rebooted without cleanly shutting down first. This error could be caused if the system stopped responding, crashed, or lost power unexpectedly.

    Since my last post, I have had 3 instant reboots, but no blue screens. Below is a link to the V2 dump after booting up from the most recent one. I'm not sure this will be of any use, though, since there was no memory dump. Since my last post, I installed yet another new graphics card. Presumably this is why the blue screens stopped. I already count the original video card I bought for this computer as wasted money even though it is under warranty. I'm confident it would test as perfectly fine. My mobo did. Perhaps I need to start counting my mobo and cpu as wasted, too, and just replace them. Pity these are not business expenses. I've been experiencing some variant of this problem since the middle of July, 2019, when I bought everything. It's my first AMD board and my first ATI/AMD graphics card in a long time. Every AMD graphics card I've ever owned hasn't worked. Worst problem I've had with NVIDIA is them starting to flake out as before the warranty ended (once) and dying right after the warranty ended (a couple times) [and others lasting for years] Thanks for any insight you can give from the V2 log.

    Thanks for those links. I had wanted to update the firmware for both my drives. Yesterday I updated the firmware for both my NVMe and regular SSD. This morning I got a blue screen that stayed stuck at 0% writing the memory dump to disk. I ran V2 anyway and uploaded it.

    At this point, I'm more concerned with finding out which computer components I need to replace. As hard as it is to believe, the CPU is the only component that has always been present when I've had problems. Is there any way for me to try a different CPU without having to pay for it if it turns out not to be the problem?

    There was no new dump file.
    The latest collected mini dump file was on 3/7/2020.

    1) Open administrative command prompt and type or copy and paste:
    2) sfc /scannow
    3) dism /online /cleanup-image /scanhealth
    4) dism /online /cleanup-image /restorehealth
    5) sfc /scannow
    6) chkdsk /scan
    7) wmic recoveros set autoreboot = false
    8) wmic recoveros set DebugInfoType = 7
    9) wmic recoveros get autoreboot
    10) wmic recoveros get DebugInfoType
    11) bcdedit /enum {badmemory}

    12) When these have completed > right click on the top bar or title bar of the administrative command prompt box > left click on edit then select all > right click on the top bar again > left click on edit then copy > paste into the thread

    13) Make sure that there is no over clocking while troubleshooting

    14) Choose one of the temperature monitoring software applications: Speecy, HW monitor, Speed fan:

    SpeedFan - Access temperature sensor in your computer: SpeedFan - Access temperature sensor in your computer

    15) Run Prime95 - Stress Test Your CPU
    Prime95 - Stress Test Your CPU Windows 10 Performance Maintenance Tutorials

    a) Record the maximum temperature and post the maximum temperature into the thread
    b) Record test duration and post the uninterrupted test duration into the thread
    c) Aim for testing > 3 hrs and abort testing as needed for freezing, temperature changes (see link)
    d) Use the Microsoft snipping tool to post images into the thread.

    16) Run Memtest86 version 8.3 (or newer version if available) for four passes.
    Repeat the test so that eight passes are performed.

    Earlier in the thread there was one four pass test result.
    If there was a second result please re-post both results or run a new test overnight.

    Please scan the QVL and compare the installed RAM to the QVL.
    If the RAM was not on the QVL what is the availability of RAM on the QVL to use for testing purposes?

    Use a camera or smart phone camera to take pictures and post images into the thread.
    In case there are any problems uploading images use share links (one drive, drop box, or google drive)

    Memtest86 has a feature to produce a text report.
    Please post this in addition to the images.

    When you have eliminated the possible, whatever remains, however improbable, must be the truth.

    I replaced the CPU and all the problems I was having are gone now.
