Sounds like you are using the Recovery CDs given to you with your computer? If so, it may be looking specifically for that 320GB HD, and in finding the 500GB, the CD determines this may not be an Acer and the install won't continue.
Either you will have to call Acer for further support, or find, borrow, whatever a copy of Windows that is not tied to Acer (OEM disk that is the same version, Home, Pro or what not) and use the key on the bottom of your computer during install. Then you'll have to manually download the drivers off Acer's site to get all your harware up and running.
