Ive had a asrock fatal1ty z68 that ive been playing around with and for some reason it wont display some websites. I first installed win xp and everything worked fine then i installed win 7-64 and that when it started. Ive installed the same windows on other computers and they work 100% This is the second mb ive gotten from newegg so i know its not user error. it's mostly yahoo sites, but there are a few others.

Im hoping someone here might have some ideas because asrock support sucks. Im using firefox but IE and chrome have the same problems. it says waiting on yimg.com in the status bar.
