I didn't see where you listed any issues except the driver disc... So, not really sure what advice to give you.
Driver discs almost always contain older drivers than what are available when you get the motherboard. Just go to amd.com/intel.com/asus.com/whatever.com to get updated drivers and quit fussing with this driver disc.
Also, when I go to the website it says this "Operating System Support for Windows 8.1/8/7"http://www.gigabyte.com/products/produc ... id=4957#sp
