A circuit card guide comprising a base defining at least one base slot for placement in alignment over a corresponding expansion slot on a computer system motherboard, incorporates one or more insert guides positioned in cooperation with the base slot such that when a user attempts to insert a circuit card by feel, due to partial or complete visual obstruction of the expansion slot by other computer system components, a connector edge of the circuit card can be received by the circuit card guide within a greater range of tolerance than the width of the expansion slot alone, and the connector edge can be guided by the one or more insert guides through the base slot and into the desired expansion slot.
