Our son was born 6 months ago. This has led my wife to work part time which has her home most of the time. We have also become much more familiar w/ wandering the house at 3 in the monring. All this considered...we are hopping on and off the computer all the time...day and night. The result is that we never turn it off. And I mean NEVER. It has only been turned off for 2 days since my son's birth 6 months ago and that was due to a possible virus problem. I have my hard drives shutting down after 1 hour and my monitor shutting down after 30 minutes. My sig should include system specs. Is this the way to go or should we be turning it off/on each night...or once a week.
