I recently bought a used Dell Optiplex 755 MiniTower.
I am running in a reoccuring problem that it randomly shuts off now and then. Usually happens when installing something or trying to run something.
I remember it restarted about 8 times when I tried to install Google Chrome. Doing some research on this topic, it seems like the PSU could be bad as it's not delivering enough voltage. But could it also be the hard drive, as it does that while something is being installed or downloaded.
