It is getting easier to use a PC right out of the box. But even with labeled or color-coded cable connections and software preloaded, some homework and preparation might help prevent a small problem from becoming a major headache. Make sure your monitor is set at eye level and away from any source of magnetic waves, such as lamps and stereo speakers that aren't designed for computer use. Don't plug in the PC until you get a surge protector.
Surge protectors come in different levels of protection and different prices.
Get a good one. Make sure you got what you paid for. Right-click the My Computer icon on the desktop screen and click Properties. Intel offers a utility program that will report all the information, including megahertz and cache amounts, that you'd ever want to know about your processor. These days, it seems as if every software application loaded on your PC wants to put its icon in the Tray area of your Task bar at the bottom of the screen, as if putting a normal icon on the Desktop weren't good enough.
