connector, as shown below. (If you are installing a
full-length card, insert the front edge of the card into the
corresponding guide inside the computer's front panel.)

(but carefully) to insert it fully. You should feel the card fit
into place. If it does not go in smoothly, do not force it; pull
the card all the way out and try again.

screw.
6. If you had to move the power supply, make sure you replace
it and secure it again with the three retaining screws.
