Chapter 1 : Introduction Introduction Once you’ve installed your operating system you’ll also need to install the device drivers, as without drivers your operating system will not work correctly and will not detect any peripherals like printers or cameras that you’ve installed. Many device drivers are built into the operating system, while newer OSes like Windows 8 can now automatically detect and install drivers making driver installation far easier than in the past. Although software installation can be complicated in some instances, this guide has been produced to specifically focus on the PC hardware, and the skills needed to construct a modern PC from the ground up. A wide range of external peripherals can be attached to a computer, although some aren’t optional 3 How to Build Your Own PC K ey PC Components Here are the key components needed to construct any modern PC system. CPU Known as the Central Processing Unit or CPU, this component can be described as the brain of the PC and is responsible for the majority of data computing and logical analysis. The CPU is usually the first item to consider when planning what parts to get for your new PC, as it often dictates the rest of the components you need to get, since certain types of processors only work with certain motherboards, graphics cards, memory, etc. Fourth generation Intel® Core™ i7, Core i5 and Core i3 processors represent a broad spectrum of performance, features and price points that the PC builder can consider. All fourth generation Intel Core i7, i5 and i3 CPUs are based on the 22 nanometer ‘Haswell’ architecture. Current Haswell based processors use the LGA1150 socket, and also integrate graphics and video capabilities, which in the past was the responsibility of either the chipset or graphics card. Intel processors can be purchased at a broad range of price points depending on clock speed, cached memory and features e.g. Current Intel Core i7-4770K and i5-4670K CPUS for example allow for dynamic overclocking features which allows the end user to increase the clock speed and thus performance. Overclocking will be covered in more depth later in this guide.
