Mine gets switched on first thing in the morning to check my E-Mail, browse a couple of my regular Sites to see if there is anything new, fire up a few of my favourite games to pass the time in between cooking meals, housework, etc, listening to streaming music on my favourite Music Channel; (Live 365)....
If I'm going shopping I either switch the 'puter off, or run a Defrag, or Virus Scan.
I ALWAYS switch it off at the socket outlet at nights, together with all other electrical appliances (except the refrigerator), to eliminate a fire hazard, whilst I am upstairs in Bed!...

...!
So...being at home for most of the day (Retired), the computer is mostly switched on, and being used...adding to my Electric Bill...and slowly destroying the Ozone Layer....(...and busy fighting off invading Aliens with my trusty Laser Blaster!)... [smiley=evil.gif]...!
Paul....in an Electrifying Mood... 8-)...!
