Hi:
I take it you installed W7 on a W8 PC?
Use this model which has all the W7 x64 software and drivers you need.
DO NOT USE ANY BIOS OR FIRMWARE FILES FROM THIS LINK
You only install the AMD graphics driver which also contains the driver for the Intel switchable graphics.
For the 8086 ID's download and install all 3 drivers listed under the chipset download section.
For the 10EC, download the Realtek Card Reader driver listed under the storage section.
For the 0004, download this one.
Best Regards,
Paul
