Hi:
First install the AMD chipset driver and reboot.
You want the first file listed on the webpage.
http://support.amd.com/en-us/download/chipset?os=Windows 7 - 64
Then you can use all of the W7 x64 drivers and software from this model at the link below, except maybe the wireless.
DO NOT USE ANY BIOS OR FIRMWARE DOWNLOADS FROM THIS LINK
For the wireless driver please do this...
Go to the device manager.
Click on the Network Controller device.
At the top of the Network Controller window, click on the Details tab.
Now you see a Property drop down list that is defaulted to Device Description.
Drop down on that and select the second item (Hardware ID's).
Now you see 3-4 lines of characters, the top line starting with PCI\VEN.
Post that top line of characters.
