It might come from your browser or from your anti-virus program which is blocking flyertalk.com webpage to load properly.
Best thing would be to run a complete check of your system + run a full defrag of your HDD.
Second, check if something changed in your web browser properties. I don't know which one you use, Firefox, IE, Opera, Safari...
If you still have the same problem, then it's time to do a fresh install. In other words, format your HDD and re-install Windows and everything that comes up with.
Hope this helps.
