Now if you are a PC enthusiast or a expert it is a good idea to stay up on hardware. Hardware is always changing and its not to hard to understand. Its amazing how even the smallest device has to communicate with the system. You will see after going through some of these guides that the motherboard seems central to all components. Now most of these guides are a good source but by no means complete. There are sites out there that devote all content to just one component. So that should give you a idea of how much there is to this stuff. I will make sure you have a good understanding of each part so to help you out in future endeavors.
