Shut down or leave running?
The Power Supply Unit (PSU) of my computer recently gave up the ghost. The computer internals all had to be transferred into a new casing complete with new PSU. (Old casing too small for the new PSU).
The man in the shop said that 3 years (the age of my computer) is about the average life expectancy for a PSU.
My wife says that it's my fault because I leave the computer switched on for too long. (Generally I'll start it up whenever I first want to use it, and shut it down at bedtime).
I say, "nonsense woman, it's your fault for turning it on and off too often. There are dozens of computer terminals in the hangar where I work. They are all left running 24/7 without problems."
Does anyone else have an opinion?
