Hi:
The product specs page indicates it has Intel hardware.
If the product specs are incorrect, then the drivers from that model I posted for you in reply to your PM won't work.
You need different drivers for an AMD PC.
First install the amd chipset drivers and reboot. You want the first file listed on the webpage.

Then use the W7 x64 drivers and software from this model on yours.
DO NOT USE ANY BIOS OR FIRMWARE DOWNLOADS FROM THIS MODEL
