After you have inserted the standoffs and lined them up with the screw holes on the motherboard,
carefully attach the screws to secure the motherboard to the motherboard tray or case
(see Tip below), depending on your chassis design. Figure 19.17 shows a motherboard attached
to a tray. Note the use of the thumb and forefinger to stabilize the screwdriver tip. This prevents
accidental slippage of the screwdriver tip off of the screw, which is one of the biggest causes of
new board failures.
