why power off?

[skayqz]

Hi, i was randomly watching a youtube livestream and it just suddenly powered itself off, not a shutdown, the pc just went off suddenly, without any warning or anything, this happened minutes ago as i am writing this.

After that happened i check to see if my outlet was loose or something but after an unplug and plug back everything went fine.

Dell optiplex 790 sff btw.

The most likely causes would be overheating or a PSU protection tripping.

 

Do you have HWInfo64 installed so you can see what temperature your CPU and other components are running at? Also, have you recently cleaned dust out of your PC, including blowing dust out of the PSU? And have you made sure that the fans are working?

Another thing to check might be Windows Event Log, see if there's anything in the system log that could indicate a cause.

That isn't the sensors screen that shows temperatures. That's just showing system information.

 

When HWInfo64 starts, check the box for "Sensors only" to see temperature info.
