Go to the page that you want to be your home page.
Go to "Tools" (Upper right side of internet page if you use IE)
Click on Internet Options
In the General Section, at the top, is a place to create your home page -- which will have you current (incorrect) home page.
Click on "Use current" and follow the instructions.
You may have to close the browser and log off the PC to have the change locked in. It's been a while since I've had to do this -- so if it doesn't work to your satisfaction, read through the instructions and try again.
If you're using a browser other than IE, you can access the Internet Options window via the Control page in your start menu.
Hope this works for you. If you had to make adjustments, add your comments to this blog so we know what works.
