Before downloading and install this driver, i would like to outline several things. First windows 7 is Driver friendly OS (only for new model), which mean some of the driver already installed, so here is some important thing:
1. Normally the drivers need to be install is: Graphic (SMSBUS), Card Reader, Infrared, Quicklaunch, Modem and Touchpad.
2. Other Driver like sound, if you heard sound, no need to install audio. Similar to wireless and other, if they work no need to install.
3. make sure to check windows updates, there are 2 sections which is critical updateand optional updates, select optional updates and there you will see several updates for your driver especially graphics.
