Your Internet Explorer could have some incorrect settings in it. My suggestion is to follow my advice to reset it. Above all, do not use Internet Explorer and use Firefox at your earliest opportunity.

1. Open IE.
2. Go to the TOOLS > INTERNET OPTIONS
3. Click the CONNECTIONS tab and remove ANY connections listed there. You don't need them.
4. Click the ADVANCED tab and click the RESET button. Click OK/YES on any prompts.
5. Click the SECURITY tab and press the button Default or Set all zones to Default level .
6. Click the GENERAL tab and about half-way down under Browsing History, click DELETE . Click OK and wait for it to complete.
7. Shutdown and restart your computer.

After following those steps, you should be able to access Facebook. Please do not use IE, instead, upgrade to Firefox. It's a better browser - http://www.mozilla.com/en-US/firefox/ .
