I am working on a friends old laptop HP pavillion ze4900. I loaded up windows 7 and every driver installed except for the "Video Controler." The display adapter drivers are installed fine but in the "other devices" section it has a "video controller" with no driver installed. I cant find anything about it and its causing WOW to not work at all. So my question is, where can I find the "video controler" drivers. Its as if they dont exist.
