Clarifications

if anything it will save (a little bit of) electricity.

The computer doesn't care if the screen is on or off or even connected, either way the computer will still send a video output.

I turn my monitor off whenever I do long tasks, e.g., defrag, virus scan, ect.

Right mouse click on the Desktop and select Properties. Screen Saver then Power. Check the Power Schemes. I use this setting as opposed to turning the monitor physically off.

For desktop PCs, choose the Home/Office Desk power scheme (it's likely on by default). Under 'Turn off monitor', pick times you feel comfortable with: 'After 15 mins' for the monitor'.

Is if the Process running falls over or the OS fails you will be unaware of it happening but otherwise there is no possible harm that can be done.

The worst that will happen is you loose a bit of time.

However if you mean is it safe to turn the monitor off and then leave the location with the computer running the answer is a Most Defiant [b]NO[/b] it is not safe. Like any other electronic device the Computer draws it's power from the Mains and if something goes wrong there it can cause damage to occur. Things like Thunder Storms which result in Lighting Strikes will destroy connected computers. Other Power Disruptions can cause damage as well. Most of these occur when power returns not when it goes out with the exception of Lighting trikes or other massive Over Voltage Events occurring.

It is possible that the computer can cause a fire and destroy the building it is in and it left unattended this is much more likely to happen than if there is someone there to turn off systems when adverse conditions happen.

Is it harmful to shut your eyes when thinking?
