Hi:
You can use all of the W7 x64 drivers and software from this model on yours except the Intel graphics and audio, for which I will provide the links below.
DO NOT USE ANY BIOS OR FIRMWARE DOWNLOADS FROM THIS LINK
Intel Graphics: Important...you must install the Intel graphics driver and reboot, before you install the NVidia graphics driver.
Audio: Accept the agreement, download and install the second driver on the list.
