For decades, one of the most persistent headaches for PC users is watching your cute and fun screensaver pop up just when you least need it. Like, when you're downloading software or watching a movie.
Suddenly, the screen goes dark and a screensaver pops up, such as the familiar silver 3-D words "Windows 7" that spin in circles against a black background. Of course, those screensavers are meant to prevent your computer from sitting idle for too long and burning images into your screen.
Note: We at Komando.com reported last year that screensavers don't serve much purpose beyond being fun.
Still, a lot of people use a screensaver and groan when it pops up in the middle of doing something important or fun. Even if you don't use a screensaver anymore, your computer might go into Sleep mode if it's idle too long.
Invariably, it takes a minute or sometimes several frustrating minutes of shaking the mouse to turn off the screensaver, or wake from Sleep mode, and get back to what you were doing.
