do you shut down your computers?

Laptop, never.
Desktop, I dont use all that much so usually I'll turn it off just to save power.

No my work computers just get rebooted once a week coz I need them on for the software I have answering calls.
Home computer always gets shut down coz I only use it like once every couple of months (only coz im always at work lol)
My dad hasnt shut his PC off for years and I swear this is why it is running so bloody terrible but he wont listen to me and says he will only shut it down when need be - need be?? when is this?
