Back up any important data, so that if the worst happens to your computer, you won't lose your valuable information. Use a DVD-R, a USB drive or an external hard drive for the best results.
Check that you have removed all disks from the computer before you shut it down.
Shut down the computer.
Unplug the power cables and all cables to peripherals, like your keyboard and mouse.
Coil each cable and secure them with twisty ties so they do not get tangled.
Loop a piece of masking tape around each cable and label it with a marker. Store them in a cardboard box.
Pack your monitor and CPU in the original boxes, secured by the hard Styrofoam packing, if you still have it.
Wrap your monitor and CPU in several layers of bubble wrap and tape it in place, but only if you do not still have the original packaging.
Load the computer into a sturdy cardboard box. Fill the rest of the box with packing foam to protect the computer while in transit.
Steal the box shut with packing tape and label it as "FRAGILE."
Carry the box from the bottom to prevent accident or injury.
