The power port on my motherboard was broken, so I bought a new MB. After installing the MB, World of Warcraft is displaying abstract shapes and preventing me from seeing where I'm going. Of course the shapes go in and out as the character and terrain change. I've reloaded the OS but still having issues. Any ideas? It is a ASUS G55VW. the MB is the same model and part number as it had before. Any help is appreciated.
