You can't actually reformat when it's off. You'll need to power it up with a bootable CD or floppy disk which has the format command available. Besides, what you are formatting is the hard drive, not the computer.

The Central Processor Unit (CPU) of a computer is the heart of a PC that processes (like a huge bank of switches) the instructions and information passing through the computer. As such its configuration changes from microsecond to microsecond as you use the PC.
