Yes but you might want to also upgrade your system memory to 2Gb if you currently only have 1Gb installed. A great program that will find the latest drivers for your system, with Windows 7 installed is called drivermax, which I use almost daily. You can use the free version which allows you to download 3 or 4 drivers per day. You can get the program here.
