Sony VAIO, VGN-NS235J Drivers

Hello,



Im having problems finding and installing the proper drivers, for my notebook. I have a Sony VAIO, VGN-NS235J. It came with windows vista 64, which was not compatible w/programs that I use. So, I installed Windows XP Pro. I also downloaded some of the drivers from the internet, but not all of them worked. I need the proper device drivers for wireless card, mousepad scroll, webcam, etc.. Please tell me someone knows an easy FREE way to get it done. Im unemployed, losing what little marbles are left in the bowl, and frustrated.
