GA-MA785GPMT-UD2H (rev. 1.0) BSOD - Drivers

So I'm stuck...

HTPC:
GA-MA785GPMT-UD2H (rev. 1.0)
- BIOS F3
Athlon II 245
- stock
G.Skill DDR3 1333
- stock
Seagate 500GB
Antec 380W PSU

I've wiped the HD, Prime tested the CPU, and Memtest + the RAM (all via UBD)
I've installed Windows 7 Pro x64 (which I would like to stay with, but I have the option to use x86).
I can install and get to the desktop, but whenever I restart I would get random BSOD; everything from memory errors to driver errors. However, another restart and everythings fine. I download drivers from the Gigabyte site and installed the ATI display/chipset driver (restart BSOD, driver ACHI.sys?). I upgraded the BIOS to F3 via QFlash(BSOD rdyboost.sys) Now I even tried to put in my win 7 disk and preform a repair and I get a NSFT.sys STOP 0x00000024. I've tried multiple different installs and wipes and now I'm getting a sector error in Boot & Nuke, but Seagate tools says everything is fine.

Final note for today... The HD I'm using was in a ReadyNAS Duo for 1 year and the last SMART check I did before pulling it from the unit said it had 2 unallocated errors, far below a damaged drive. I do not know what todo. I will try another wipe and install this time using the Gigabyte SATA drivers (preload) although why would the system be able to install with generic drivers if I needed to do this.

Please give me suggestions anything would be great.

So I'm back at it after some thought... I'm trying some newer drivers I found, not the ones on the supplied disk, for the SATA controller, however the windows installer doesn't show them until I uncheck the "compatible hardware drivers only" box... normal?!? I'll keep this posted for anyone watching...
