Depends what OS do you have in pc. If you are using windows xp, the connection between phone and pc isn't even ok.
You can try to install samsung drivers ( just google: ''SAMSUNG USB DRIVERS FOR MOBILE PHONES'' , and get the lastest version)
Then depends what
android version do you have.
If you
are running the stock gingerbread, the connection type is
Mass Storage
If you
are not running gb, your phone will connect by defaut, as
MTP Device. This doesn't require special drivers, so is working also with xp.
