Very strange problem with installing windows

I have just purchased a new motherboard - the Gigabyte GA-MA790X-UD3P. I have downloaded the RAID drivers from their website, and loaded them up onto a flash drive.

When Vista is installing (I have 64 Premium) it recognises the 32bit RAID drivers, yet even when I'm laying the 64 bit ones out in an identical folder/file layout setup refuses to read them.

Can anybody suggest what's going on? I want to install Vista 64, which I'm guessing you can't if you start off with 32bit RAID drivers.

I have tried them with different memory sticks.

I'm guessing this is a software problem rather than hardware, so you might get better help in the Operating Systems forum.

My guess is it's something to do with the way 64bit drivers have to be properly signed.. but you say it recognises the 32bit RAID drivers, so is there a problem just using them?

Do you have both 32 and 64 bit drivers on the same flash drive? Try removing the 32-bit and just use the one 64-bit folder - Vista could be getting confused.

I have tried all combinations of that - even doing 32bit drivers twice under different folder names. Setup recognises both sets perfectly fine.

I'm also leaning toward the fact that for some reason the 64bit ones aren't signed (why?). I've got the only ones possible from Gigabyte's site - and neither for love nor money can I find the appropriate ones from AMD's. :(
