About 5 years ago, I asked all my PC Tech friends this question -- for home users, should they turn their PCs (old and new) off at night, or leave them on.
Exactly half the guys said -- Turn it off. You'll get less dust -- dust is the killer. General rule of thumb -- less time on means less heat, means longer life.
The other half of the guys said -- Leave it on. Parts burn out when you turn on the PC and the current runs thru the PC. So just leave it on, using restart when necessary. If it's a good PC, the fan will keep it cool. And a screen will keep the dust out, etc etc.
Do you guys agree, is it 50/50? Or has it changed in the last 5 years?
