Change your screen saver

Right click any empty space on your desktop (what you see when you turn your computer on).  Click “properties” – when the box comes up, click the screen saver tab at the top of the box.  There is a scroll box (with down arrow on the right side) that contains lots of options.  Once you have picked one you like (they preview in the box), you might take the time to explore the other options the box provides.  Last step is to click the OK button.
