Here at DIY PC we know that you are a computer parts geek and very knowledgeable of everything computer, but what about your significant other?  Does your girlfriend try to act interested in your DIY hobby but finds your explanation of what exactly a CPU or a memory stick is too dry and boring to understand?

Do not worry because we now have “introduction” articles to help you explain the components of a computer to anyone who may ask.   Today, were going to start with the main controller of all that is computer or gadget, today we are looking at the motherboard.

The motherboard, or logic board as it is sometimes called, is the main printed circuit board in your computer.  This board holds all the other components together.  The CPU, memory and all I/O functions are either housed on this main board or attached through expansion slots and cables.  In some cases a component can be upgraded by simply popping the old component out of the socket on the motherboard and inserting the new upgraded component.

Motherboards are found in every electronic device manufactured.  If your toaster has an electronic display or an automatic toast detection system, there is a motherboard inside.  Motherboards come in all shapes and sizes but their function is the same, connect all the devices needed to run the device together and provide pathways for the electricity to move.  

Whenever you upgrade a component in your computer, you should verify that the new component is compatible with not only your CPU and hard drive but your motherboard as well.  The operating software for your motherboard is located in the BIOS.  If you purchase components that will not work with the BIOS software available for your motherboard, you will be forced to change your motherboard.  

Many new motherboards are sold as a bare-bones computer system, you plug in a few key components and your new computer is up and running.  When purchasing a new motherboard it is advisable to purchase a case that is compatible with the motherboards shape and size.  Not all motherboards are built to the same size and dimension specs.  If you try to remove your old motherboard from a case and install a new one, you may find that your new motherboard will not fit. 

If you have the same motherboard you were using in your first computer, chances are at some time you will need to replace your motherboard.  Motherboards have a limited amount of connections available for components as your desire for more speed and memory increases you will eventually max out the available connections on your motherboard.  Review your motherboard’s capabilities at least once every twelve to eighteen months to make sure you will be able to upgrade the additional components when the urge hits.  

Your motherboard is the infrastructure of your computer and your electronic devices.  Without all the components plugged into the motherboard, your motherboard is useless.  However, without your motherboard your CPU and hard drive could not do much either.
