Trouble loading Facebook, nothing else.

Hi, I've been having so many problems with loading Facebook yesterday and today. I was first using Internet Explorer and then it happened. I then downloaded Mozilla Firefox and used it for about 45 minutes and then it happened again. I RELOADED Firefox and it worked for about 5 minutes then gave me the jumbled page that looks like this:

I can still access it from a friends computer and from my own computer if I use AOL. Is this a virus? What's up? Anyone know? My Virus and Spyware program doesn't find anything. I've run numerous scans.
