Since January 27, 2019, my computer has been randomly shutting down. Critical Event reads: "The system has rebooted without cleanly shutting down first. This error could be caused if the system stopped responding, crashed, or lost power unexpectedly."
Source Kernel-Power
Event ID 41
Task Category (63)

The system never shuts down while I am using it. If it sits idle or is in sleep mode, it will shut down about 75% of the time. I can't really see a pattern.

Although the computer is a few years old (2012), the power supply was replaced late 2018.

Any suggestions?

Thanks,

Tundra

Downloading very slowly. Will report back ASAP. How long should I let it run without (possibly) causing a shutdown before concluding the test?
 
I have never experienced a shutdown while I am actively using the computer (typing, mousing). It only shuts down when it is idle or sleeping. The only loads are the processes were left, such as Norton, IPVanish, open browser windows, OpenOffice, whatever... The only requirement for a shutdown is nobody typing or moving the mouse. If I was to leave the computer alone and sit staring at the screen, I am fairly sure it would shutdown within 15 minutes. In fact I will try to do that in case some message is displayed before the shutdown. When I put the system in sleep mode when I know I am going to be away for a while, it seems that the shutdowns occur less frequently.

I experienced a couple of BSODs a few weeks back, but not lately - even though I get several shutdowns every day.

The machine does not reboot. But, I have disabled "Automatically restart" in "Startup and Recovery".
 
Well, I left the system idle and tried to watch the screen until it shutdown. I had Task Manager open to "Processes". I also had Speedfan utility running and it showed the CPU temperature spike to 54 degrees C from 37 C. At the same time, Task Manager showed "NortonSecurity.exe" at 60% of CPU usage.

I terminated the experiment to try to find out why Norton (or whatever) was spiking the CPU usage and the CPU temperature.

Well, somewhere along the line I must have done something because the system has gone three hours without a shutdown.

I believe the shutdowns were caused by a temperature issue. If it resurfaces, I will look into addressing any kind of temperature problem before I re-post.

Thanks
 
Please close this issue.

I have not experienced the shutdowns for over 5 days even leaving the system on and idle overnight.

The changes I remember making:
1. Setting Power Plan to "Balanced" from "High Performance".
2. Confirming that all hard drives be allowed to sleep after 5 minutes on no activity.

I still believe that my previous configuration somehow allowed CPU activity to spike (even though "idle") and CPU temperature to rise beyond safe threshold, thereby triggering a shutdown to avert harmful thermal overload.

Thanks for being there.
