Have you tried fiddling withthe settigs in the internet options to see if they let you access the sites?
What does the error message say when you try to access them?

There is nothing wrong with the internet options i suppose..
There is no error message shown..When i type the url, the status bar shows "Waiting for blahblah.com" and there's this blank screen where nothing shows up.As I told this problem is with certaqin sites only.
Actually the problem is worse now.I can't even access this forum from my laptop(which i was able earlier when i posted the first time)..
