Replacement Note:
Align the card’s connector with the expansion slot and press until the
connector is inserted all the way into the slot. If you’re installing a 12-inch card, make sure
the card engages the appropriate slot in the PCI card guide.
Don’t rock the card from side to side; instead, press the card straight into the slot.
Don’t force the card. If you meet a lot of resistance, pull the card out. Check the
connector and the slot for damage or obstructions, then try inserting the card again.
Pull the card gently to see if it is properly connected. If it resists and stays in place,
and if its gold connectors are barely visible, the card is connected.
