2. Align the cards connector with the expansion slot and press down until the connector is inserted all the way into the slot. Install the card in the same slot used for the original card. Dont rock the card; instead press it straight into the slot. Dont force the card. If you meet a lot of resistance, pull the card out. Check for

gold connectors are barely visible, it is connected.
