Entering Facebook URL locks my entire notebook for 45 seconds

[Depo1964]

For around the last 4 weeks, whenever i enter the Facebook URL www.facebook.com or https://www.facebook.com into my navigation toolbar box (Firefox 21.0) my entire notebook PC (HP Pavilion dv6500) locks up completely.

I can't use the mouse or click on anything else for around 45 seconds when the Facebook login screen appears.

i am running Vista Home Premium SP2.

This only happens the first time that i attempt to access facebook after either a reboot or when first starting up my notebook for the day.

I always close my browser after leaving facebook.

But when i try to access the facebook URL the following times, it only takes a couple of seconds for the FB login screen to appear.

This is the only URL which this is happening with. It also happens when i use IE 9, as well.

I have tried several things to fix this problem.

1. Full scan with malwarebytes. 0 problems.

2. Full scan with my antivirus sw. 0 problems.

3. scan of my registry searching for facebook. Did turn up several occurences mostly having to do with the Bing toolbar which I then removed.

Also, removed older references of FB in my registry. It is now void of any referrences to FB.

4. searched the Windows Event viewer Logs for the precise time that I hit Enter to go to the FB URL and could not find anything in the logs at that specific time.

5. left a request on FB Help for this problem, for which i received no "human" response.

i notice the last item that is loading when i click Enter to start the FB URL search in the lower left hand portion of my screen (and then it locks up) is fbstatic-a.akamaihd.net....

All google references to the above URL indicate that FB uses this server address to load member photos and such.

But i haven't even logged into FB when the above problem occurs.

Are there any analysis tools that i could use, besides the Windows Event Viewer, to try and find out what is going on internally on my notebook PC?

If not, I am going to close my FB account. This, to me, is scary stuff.

Any other ideas of something else I might try to fix this problem?

thx.
