5. Disconnect all the wires. Of course, before doing anything else and before you start unscrewing all the parts, make sure that everything is disconnected. The least you would want is for the other parts to be damaged. The power supply is very easy to spot since the connecters are big, however, the small connectors such as the power switch or the USB connectors on the front of the CPU are barely seen.
6. Remove all the hardware. Aside from the connectors, you must also remove the hardware installed on your old motherboard. There are cases wherein hardware devices obstruct the motherboard when you try to take it out. Do not force it. Removing everything inside your CPU prior to installation is a much better idea.
