Does it show up in iTunes?

See

iOS: Device not recognized in iTunes for Windows

- I would start with

Removing and Reinstalling iTunes, QuickTime, and other software components for Windows XP

or

Removing and reinstalling iTunes and other software components for Windows Vista, Windows 7, or Windows 8

However, after your remove the Apple software components also remove the iCloud Control Panel via Windows Programs and Features app in the Window Control Panel. Then reinstall all the Apple software components

- New cable and different USB port

- Run this and see if the results help with determine the cause
