graphics problem.....

im trying to play world of warcraft on my inspiron 1525 laptop and it has a serious graphics problem, i know that this laptop can play it because it has all the requirements and i evn ask on wow fourms and 50 people said yes. my laptop runs the game the graphics are just messed up. if you are firmilliar with the game the boxed under the purple xp bar are all invisible accept for a white line around them. the ground is textureless no grass or anything accept for a plain green sheet of paper looking ground. the words on the loggin screen for example the words such as quit, options or loggin are ushaly white and in a red box, on my laptop their just yellow words no boxes or anything.
