When you first get a new PC, you have to get everything set up, connected, and ready to run. If you’re using a traditional desktop PC, setup involves plugging in all the external devices—your monitor, speakers, keyboard, and such. If you’re using an all-in-one desktop, the task is a bit easier because the system unit, monitor, and speakers are all in a single unit; all you have to connect are the keyboard and mouse.
Setup is even easier if you have a notebook PC, because all the major components are built in to the computer itself. Same thing with a tablet; there’s really nothing to connect.
If you’re connecting a desktop PC, or even a notebook with external peripherals, start by positioning it so that you easily can access all the connections on the unit. You’ll need to carefully run the cables from each of the external peripherals to the main unit, without stretching the cables or pulling anything out of place. And remember, when you plug in a cable, make sure that it’s firmly connected—both to the computer and to the specific piece of hardware. Loose cables can cause all sorts of weird problems, so be sure they’re plugged in really well.
