i would repair Internet explorer like JustinOhioRR was saying
and if that doesnt work, you can reinstall windows if you want, or could switch to FireFox or something
oh, and im not sure if this will work, but you can try and download this thing called Maxthonhttp://www.maxthon.com/en/index.htm
its basically a souped up internet explorer
IE alone is like a civc....with maxthon its kinda more like a civic with bodykit, xhaust system, and multiple seat position buttons
