Vista Not connecting to internet.

Hi

I have Vista  installed on HP G70  Iam not able to connect to the internet at  all of sudden.
I tried at home as well as in the work. It picks up the IP both at home and work but when i go to google or any wesite it says wepage cannot be displayed.

I also did a system restore and tried to install IE8 , it says the laptop has a higher version unstalled already. But iam running IE8

I  also tried connecting through wireless at home , its the same.

Ant help to troubleshoot and sort this problem will be a  great help.

Thanks

try opening a web browser and typing http://74.125.230.148 

should take you to google.com if it doesnt it points towards a DNS issue.  check the IP address isnt a locally assigned ip address (169.x.x.x)

Check you local IP configuration.
CMD | ipconfig /all | ENTER

Check your browser that you haven't checked Proxy box accidentally:
Internet Options | Connections | LAN Settings
Clear the Proxy box.

Try to ping www.google.com in CMD, post results here.

If none helps, are you using any kind of third party firewall / internet security applications. For a test try to remove those from the system.
