So I can suggest some troubleshooting first of all:
- create a new user under windows 7 and try it under the new user
- test the device with an other computer or an other device with your computer
Like this you already will have some basic info where the issue is: as with the device or with the computer, and aswell if with the computer then if its system wide or only user issue.
You can try aswell updateing windows and unable the firewall/antivirus to be sure is not somekind of conflict.
From iTunes part you can try a full reinstall of iTunes following this art.: http://support.apple.com/kb/HT1925
Hope it helps,
