Actually we usually speak of reformatting the hard driveon the computer. The computer's hard drive is the internal drive that has no removable media. On it will be stored the operating system (such as Windows or Unix), most of the applications (programs) you use, plus all kinds of data files. A hard drive is a disk (or set of disks) with a magnetizable coating on which a recording head can write information. Each kind of computer and operating system has its own way of formatting that information, but they all write in concentric circles, grouping the information into smaller blocks or sectors. Before data can be stored on a hard drive (or any magnetic disk, actually), it must be formatted. This process magnetically creates the writeable areas on the disk. To reformat the disk means to recreate these areas, refreshing the disk to a new state. A full format permanently erases everything on the disk as part of the process. A "quick format" may be available, which will not bother to erase everything but will just mark everything as erased, with pretty much the same result. (Custom programs may be able to recover some erased information, but only if it has not yet been overwritten.) Generally, when you reformat a hard drive--at least, the primary drive on the computer--you want to make it bootable, installing on it the components of the operating system that allow you to run your computer.

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. Or you can remove the hard drive from the computer in question and format it in another computer.
You can not 'reformat' a CPU. 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. The only things you can reformat in respect to a computer are its data storage devices (normally disks) and the process usually involves overwriting anything that was on the disk before and starting clean. Be warned, if you reformat your system disk you will lose your computers operating system and it wont work afterwards!
