Can you more descriptive? When you open IE or Chrome, does it show the window then close? Does it not open at all? Does it open but only show a white screen?
If it only shows a white screen then chances are you're not connected to the router or your router isn't connected to the internet. If it doesn't open at all, you should try restarting your computer or reinstalling it. If it opens then closes then there may be something on your computer blocking it like an anti-virus.
Well so i have this problem like 20% too The reason of this problem is about your host.. whenever you open chrome it says in right bottom "Resolving host" but it doesn't receives anything yet So just reboot in order to fix it hope it works
