Preparing the Motherboard Installing the CPU Be very careful when handling the CPU. Hold the processor only by the edges and do not touch the contacts on the motherboard or CPU. Any physical damage to the motherbard pins will void the warranty. Use the following procedure to install the CPU onto the motherboard: Unhook the socket lever by pushing down and away from the socket. Pull the socket lever back and the load plate will automatically lift. There is a protective socket cov

Securing the Motherboard into a System Case Most system cases have a base with mounting studs or spacers to allow the motherboard to be secured to the chassis and help to prevent short circuits. If there are studs that do not align with a mounting hole on the motherboard, it is recommended that you remove that stud to prevent the possibility of a short circuit. In most cases, it is recommended to secure the motherboard using a minimum of nine (9) spacers and screws. 1. Carefully place
