The first step to replacing a motherboard in a desktop computer is to remove the old motherboard. That may sound trivial, but it's literally half of the job, and I'm splitting removal and installation onto two pages so it doesn't get too big. In order to remove the motherboard, you not only have to disconnect all connections between the motherboard and components in the case, you should also remove any cables that are simply in the way. Remember to touch the metal edge of the case to ground yourself from time to time. Some techs like to leave the power supply plugged in for a ground, but that's pretty crazy with ATX technology, since if the switch on the back of the supply goes on, the power supply will be live. I unplug the power supply and avoid dancing on the rug to generate static electricity. We start by removing the 1x4 power connector from the hard drives.
