theres another homepage on my browser how can i go back to the old one?

Answer 1

Go to the page you want to be your honme page
Click on Tools in the menu
Select Internet Options
Click on the button near the upper right that says "Use Current"
That will make the current page your home page

Answer 2

You could do it like the first answerer said, or, if you have Internet Explorer 7, go to the site you want as homepage ans you could click on the arrow by the little house that stands for your homepage. Click on "Add or change home page...", a box will appear and you want to click on the top button, "Use this webpage as your only home page".
