After reinstalling Windows have you installed all other drivers?

Are there any device errors listed in Device Manager?

Are you trying to install the correct driver version? If your OS is 32-bit make sure you are only installed the correct one.

You can get your driver here.
(choose the correct device and software)

Can you install the device on another PC.

Can you post a screenshot of your Device Manager? http://www.techsupportforum.com/forums/f215/how-to-post-a-screenshot-184291.html
