3.Push down near each slot to engage the grounding clip onto its corresponding tab.
4.Push evenly on both sides of the system board as you slide and lock it into position (do not twist the system board).
5.Reconnect all cables to the system board.
6.Replace the airflow shroud.
7.Replace the expansion-card cage.
