Little black squares

Eight out of the box, FS9 gives me little black boxes around trees, runway lights and strobe lights on the wings......at this point, the sim is unflyable. I have a vanilla XPS 8100 from Dell, 500Megs of Ram. 1.3 MHZ.Framerates go from 20 to 7 when I go to cockpit modesI also could not get anti-alias to show up.Very skeptical at this point. My first reaction was ...migod, it looks just like FS2000.
