bsod

I just changed my disk setup from:

1 SATA HDD Primary OS Disk 2x SATA HDD Backup Disks in RAID 1

TO:

1 SATA SSD Primary OS Disk 1 SATA HDD Backup Disk [No RAID]

Everything worked great, no problem. So, since I don't have a RAID array anymore, I decided that I could change my BIOS setting to AHCI instead of RAID. I have a Gigabyte GA-P35-DS3R v1.0 mobo.

These are my steps:

Settings > Integrated Peripherals > "SATA RAID/AHCI Mode" = RAID --> Changed this setting to AHCI
Reboot
Windows Start screen shows up, but as the color orbs are spinning into focus, BSOD and immediate restart
Repeated reboot several times, same outcome

Next Step:

Launch BIOS settings
Integrated Peripherals > "Onboard SATA/IDE Ctrl Mode" = RAID --> Changed this setting to AHCI
Reboot
Windows Start screen shows up, but as the color orbs are spinning into focus, BSOD and immediate restart
Repeated reboot several times, same outcome

Switch both settings back to RAID, reboot, and Windows starts up just fine, no issues.

What am I missing? Why can't I set it to AHCI mode without BSODs?
