RAID for Windows 7 on a Gugabyte MA790FXDQ6

Hello,

My motherboard is: Gigabyte MA790FXDQ6
I have just bought two brand new WD 500 GB RE4 HDD's and connected them coorectly for RAID 1.
I have changed the BIOS and Pressed Ctrl+F to create the RAID and this has been successful.
When installing Windows you obviously get to the aprt where you need to load the floppy drivers to locate the drives...

I have downloaded ever driver from the Gigabyte support drive and loaded them onto a USB, not one driver can be seen when the USB is "Browsed" too...

How important is it that the drivers are on a floppy, as I do not have a floppy drive or access to a floppy and drives.

Also what driver should be downloading as I tried the 3.2.1540.17 one and that was not seen, so I just downloaded them all in an attempt for success.

I have tried using the other GSATA ports too...
I was told on Seven Forum that my motherboard was too old to run a RAID for Windows 7,

WOULD BUYING A SEPERATE PCI RAID CONTROLLER FIX THIS? And is there any cheap ones that work with windows 7?

Any one with any advice its greatly welcomes thank you in advance
