5.Grip the card firmly by the top comers and position it at the top of the slot, as shown below. Make sure the connector pins point down and the component side faces the power supply inside the computer.
6.Insert the card into the slot, guiding it straight down. Once the connector pins reach the connector slot, push the card downward firmly (but carefully) to insert it fully. You should feel the card fit into place.
If the card does not go in smoothly, do not force it; pull it all the way out and try again, keeping it straight as you insert it. Examine the card to verify that it is fully seated in the slot along the length of the connector.
