Your Dell desktop computer will come with all of the equipment you need to hook it up and get it started right in the box with the main CPU. You will have all of the peripheral equipment and cables that you need to connect your desktop to your keyboard, mouse, monitor and, most importantly, a wall outlet or surge protector to provide it with power. The entire hook-up process shouldn't take more than a few minutes. Connect your computer monitor to your Dell computer using the included blue VGA cable. This VGA cable plugs into the blue video input on the back of your Dell computer and into the identical input on the back of your monitor. Plug your monitor's attached power cable into a wall outlet or surge protector. Plug in your keyboard and mouse. Dell computers ship with USB keyboards and mice, so take the USB cables that are permanently connected to each device and plug each of them into one of the available USB ports on the back of your Dell computer. You can use the ports on the front of your computer if you like, but as your keyboard and mouse don't get unplugged with any kind of frequency you may want to conserve those inputs for removable devices like flash drives. Connect your Dell computer to a wall outlet or surge protector using the included power cable. The power cable plugs into the power outlet on the back of your Dell computer and into a regular power outlet on a compatible device. Press "Power" on your Dell computer as well as on your monitor. Your computer will turn on and begin to boot into Windows.
Hope this helps. For reference, you may want to read this section describing the cables and connectors coming from the power supply
, and/or this section describing the connections on the motherboard
. Motherboards and system cases vary. Your motherboard may not have all the items I mention here, and the same holds true for your case. Furthermore, you may find that your case and motherboard don't match in every situation; for example, some cases have a turbo button and some do not, and some motherboards have a connection for a turbo button and some don't. Watch out for "off by one" errors when attaching cables to pin headers. In particular, some motherboards combine several pin connectors into a larger block. The individual connections are the same, the motherboard just physically groups the pins together into a larger matrix. Be careful when working with these as making a mistake is much easier to do. Refer to the manual. If the system is in a tower case, it is much easier to perform this procedure with the case resting on its side. LEDs have two wires and are unidirectional, so they will not work if attached backwards. You need to connect the positive lead from the case to the positive pin on the motherboard, and the same with the negative. Unfortunately, the case connector almost never has the positive and negative labeled. Fortunately, attaching them backwards will usually not cause any damage; the LED just won't work. One tip you can use: most cases employ for each LED one colored wire (green, yellow, red, orange, blue) and another wire that is either black or white. When this is the case, usually
the colored wire is positive (signal) and the black or white wire is negative (ground). This isn't always true, but it's better than a random guess in most cases.
