I use firefox, and I have no such problem with the nVidia site. I have noticed that extensions can affect page layout, and I noticed that you have AdBlock installed. Have you tried without your extensions loaded? If you don't want to uninstall them, you can try downloading a standalone version of firefox (portable firefox @ http://johnhaller.com/jh/mozilla/portable_firefox/) and viewing the site in there, just as a troubleshooting step.
Adblockers are notorius in some cases for screwing up your page view settings. I use NIS 2005 which has Ad-block but it defaults to off and I have it set to off as otherwise it can cause problems. I would try setting your advert blocker to off as everyone says to see if it helps.
Ep, glad to see you come back and tidy up...did want to ask a one day favor, I want to enhance my resume , was hoping you could make me administrator for a day, if so, take me right off since I won't be here to do anything, and don't know the slightest about the board, but it would be nice putting "served administrator osnn", if can do, THANKS
