Can you please fill in your system specs so I do not have to go through the whole thread to determine your system specs? You can use System Info - See Your System Specs
as a guide to fill them in. This will make it easier for us to recommend where you go to find drivers such as your Intel SATA/AHCI controller driver.
This is the components:
Intel Core i7 950, 3.06GHz
Asus P6T Deluxe V2
Corsair 6GB (3KIT) DDR3 1600MHz/CL9/1.65V/XMS3
1TB Western Digital Caviar Black 64MB SATA III
Gigabyte GeForce GTX 570 1280MB
Samsung SH-S223C 22X DL Svart
Cooler Master Hyper 212 Plus
Corsair HX 650W 80+
Tell me if you need to know more.
It's a custombuild by a company who do this on ordering.
