Can't get Windows 7 installed on a new rig

First I would like to say hello forum! Second, I hope you guys can come up with a solution for me here.. So the problem is that today I bought an entire new PC and assembled it completely and everything is running fine except one issue. When I boot the computer to the DVD/CD and run the Windows 7 Ultimate installation it asks me to search for the drivers. In the manual for my GIGABYTE mobo it states to insert the GIGABYTE CD and select the drivers manually. It states to select BootDrv\SBxxxW7\RAID\W764A since I'm trying to install a 64 bit version which is supported by my processor, anyway, I do this but in the selection area to install the driver NOTHING pops up at all and I've tried every single different type of driver from 32 bit/64 bit AHCI's to RAID'S, however when I select the "Hide drivers that are not compatible with this hardware" they all show up. I try installing one of those but it tells me they are unsigned drivers and just takes me back to the initial installation start up.

So please any help would do! Hope to get some help, thank you forum.
