Do you use a firewall other than windows, may have to reenable it to access the internet in that one since you reinstalled, might not, although i don't know why it would of changed before you reinstalled? May be a software default with your firewall. If it's not your firewall or if you don't have one, than I haven't a clue. Good Luck. I know a good reformat might do something, just kidding, LOL!
