First try this,
http://esupport.sony.com/perl/select-system.pl?PRODTYPE=1,24,26,66,9,70,5,72
Option 1. "Detect My Model" on the right pane. If this doesn't help, try here again,
drivers for sony via vgn-t170 series
Currently there's no drivers for windows 7 but on most systems this works.
Good luck.
Thanks for using FixYa.
