How Do I Identify My Motherboard Expansion Slots?

If you are having trouble identifying your motherboard expansion slots, there are a few things you can do. First, look at the back of the motherboard. There should be a row of five or six slots that are perpendicular to the serial ATA cables and the power supply. The slots will be labeled “A1,” “A2,” “B1,” “B2,” and so on.

Next, look at the front of the computer case. There should be a row of four or five ports that match up with the slots on the motherboard. The ports will be labeled “SATA 1,” “SATA 2,” “USB 1,” and “USB 2.” Finally, make sure that your computer has an expansion card that fits into one of the identified slots.
