on line 5-6 different times a day better to shutdown between each log on or use screen saver?

Answer 1

You should be fine just shutting down at night and leaving it on during the day.

Any sort of wear on your computer that could result is very minimal. Especially when compared to the amount of time you will waste waiting for the computer to boot up and shut down.

Also, don't use a screensaver, it is better to set the monitor to automatically shut off after 10 minutes. It will save more power and a screensaver can actually shorten the life of your monitor.

Answer 2
