Is it better to turn PC off or leave it on stand-by?

To manually put your computer into hibernation
You must be logged on as an administrator or a member of either the Administrators or Power Users group in order to complete this procedure. If your computer is connected to a network, network policy settings might also prevent you from completing this procedure.

Open Power Options in Control Panel.
Click the Hibernate tab, and then select the Enable hibernate support check box.
If the Hibernate tab is not available, your computer does not support this feature.

Click OK to close the Power Options dialog box.
Click Start, and then click Shut Down. In the What do you want the computer to do drop-down list, click Hibernate.

To hibernate, just click the start button at the lower-left corner of the Windows screen, choose shut down, then when the dialog box appears asking you what do you want the computer to do, pull down the drop-down menu and choose hibernate and voila! your PC will enter hibernation.....
