I am unable to access certain websites from my PC viz. google.com, gmail.com , stackoverflow.com, etc. However, I am able to access facebook.com, twitter.com, infoq.com etc. Currently I am accessing Google via proxy server. I suspect that the problem might exist with websites that have used ASP for scripting. Please suggest a solution to the problem that I am facing.
When you say "does not load", what happens? Does the page show up blank, or is there a browser error? If there is a browser error, what does it say? Does the page start to load but never finish?
could be your hosts file, some virus's update it.
If not that, try with other web browsers (Firefox, Opera, Safari)
If so has it been set to block all scripts or just scripts from some sites?
If it's just some sites, is it those sites on your list of inaccessible ones?
Could be a DNS issue if not access-restriction. try setting your DNS to 22.214.171.124 or 126.96.36.199
