My computer was working fine with an SSD and SATA HDs on the ICH10 and optical drives on the SATA2 controllers using AHCI for both ICH10 and the SATA2 controllers. I wanted to install Windows 7, and during the first go around, I messed up a driver install within the OS, so I went to reinstall it. When I rebooted again, the computer froze under the ACHI drive detect screen in the BIOS. None of the drives were ever detected. I then went back to IDE all around and used another HD that had a Vista install. It booted up fine.

My problem is I have changed nothing hardware related. I have tried to clear the CMOS, reinstall the F7 Final BIOS, and update the BIOS to F8b. I cannot get AHCI to detect any of my drives, but IDE mode works fine on another HD. AHCI was working FINE the way I wanted before. All I wanted to do was reboot and reinstall Windows 7. What I am saying is: all the hardware works. It has before in AHCI and works now in IDE. Any suggestions?

BIOS Settings (What I am attempting):

- All clocks auto or presets from a clean BIOS install
- ACHI for both ICH10 and SATA2 controllers
- SATA native mode enabled
- Intel SSD as drive to load OS on
- Any wake features disabled
- No floppy detect
- Power saving features not changed
