Also, to get a more useful answer, try installing Firefox as an alternative browser and install Firebug as an add-on. It manifests itself as a "bug" icon. Visit its Network-tab and try loading the page again. Each element of the page will result in one line.
If you see your GET request for the CSS/JS files fail with Status 404, then the connected webserver could not find the requested URL. In your situation it likely means your browser was connected to an incorrect IP adress or the connection was intercepted (as in: transparent proxying by 3G providers or "clever" proxying routers) and incorrectly handled.
If it says "Aborted" in a line then an actual DNS resolving issue could be the reason. right-click the GET-part on the left and choose "Open in new Tab". This will yield a more informative error message because embedded resources usually fail silently, resulting in missing images or CSS/JS files as in your case.
