Sony vaio driver

Hello,
where i must download my sonyvaio PCG6N1L driver

The driver depends on the particular hardware, and can usually be found on your manufacturer's site if you search under Support for your model. Go here: http://esupport.sony.com/perl/select-system.pl?DIRECTOR=DRIVER&SR=nav:support:electronics:drivers_software:esup , and enter the requested information. re-check your model number; I can't find a PCG6N1L anywhere. The model MIGHT be vgn-sz390P.

(the link works, despite the strange smiley in the middle)

Alternatively, a very clever member here posted directions on how to identify any hardware that needs a driver. See the second post here: http://www.tomshardware.com/forum/274306-45-video-controller-compatible-driver-windows-free-download , from Saga Lout.

Please satisfy my curiosity: how do you know that this is a driver issue as opposed to some other kind of problem?
