The motherboard can be seen as the part of the computer that ties everything together. This is usually not updated. If you need a new motherboard it would probably be because you want to update another part of your computer. Once your updating a couple things, you might consider just getting a new computer (the box itself, not necessarily the screen, printer...)

Of course if you know enough about computers to tell that it is the motherboard that is broken you probably know how to replace it...
