I have a Toshiba P100 - 286. It has an Nvidia 7900GS graphics card. There is a new download on Toshiba's site for the card so it works with Vista. My problem is that I downloaded EpressZip so I could unzip this file and install the driver but I do not know what to do or when I try to unzip the file, ExpressZip tells me that an error ocurred and I cannot go any further. Is there any other program that i can use out there or am I doing something wrong?
