install the drivers for your phone on the computer you are using to connect to the internet!

have you tried disconnecting the phone from the pc, restarting the phone and the pc, then reconnecting?
try updating your nokia pcsuite software or your phone's firmware using the pcsuite if it allows firmware update.
or take your phone to the nearest nokia service center and have a professional take a look at it.
