Issues with Facebook apps only?

[Justus]

My computer is operating fine and have no issues with viruses. Searching websites works fine, e-mail (both Yahoo and MSN) work fine, and getting to my Facebook homepage works fine. I can post a status, read posts on my page, etc. But, as soon as I try to navigate to an app (mostly games) or someone else's home page, or even my account or privacy settings, the page will start to load, then all the toolbars on the top of the screen "white out" and the computer freezes.

I am not very knowledgeable about computers, so any response in a "beginner" manner would be very appreciated.
