Ok here's the thing..its probably ur graphics driver....because I had the same problem with the game when i installed it.....turns out my graphic card's drivers messed up.......since i wasnt able to find updated for the Go 6800 Ultra from nvidia or dell's website so i switched to XTremeG drivers....works fine so far with me bro...but u may need to chk the game settings also..try out with the most basic settings and see what happens....then move on from there....should work out
