Motherboard Gigabyte GA-970A-DS3P with AMD SB950 and Samsung 850 EVO SSDs 128gb

Windows 7 Professional 64bit, refuses to accept any RAID driver at install claiming unsigned drivers. Windows 8.1 loads the driver without complaint but doesn’t see the RAID. I have trawled the web for an answer for this but I’m still left with an expensive and frustrating headache.

Addendum: Window 7 refuses to install any 32 or 64 bit driver. I have driver a dozen different driver including official AMD and Gigabyte drivers, both on the boxed discs and via downloaded drivers. Furthermore, none of the USB ports are working which I presume is preventing me from updating motherboard BIOS which refuses to access the DVD drive. Having installed many a RAID system so far this motherboard has been a nightmare.

Greetings,
Can you please share what ports the EVO's are connected to....  and the BIOS settings for for RAID Mode you are using?

Windows 7 - no native xHCI support in pre-boot environment
Windows 8 - has it

Default BIOS settings usually handle windows 7 USB support in preboot.  If you've changed them, Load Set Up Defaults and configure your RAID again, ensuring the ports match what the BIOS is expecting.  Also....  ensure you have entered the RAID Config Utility (ctrl+F) and marked the EVO's as member disks for RAID 0 or 1 whichever you are using.  Reviewing pages 28~31 in your manual may be helpful.  I hardly (RTFM) either    If there's more to the story...  like UEFI boot, please share.
