ASUS Crosshair IV Formula AHCI issue. Solved

[Tarvaln]

I'm having a weird AHCI issue with CHIVF.

I was running bios 2101 with a 1090T CPU. Windows 7 x64 was installed with AHCI enabled on bios and worked fine for months.
I bought a 8350 and upgraded my Bios to 3029. It defaulted my SATA back IDE. However, now when I switch to AHCI Windows won't boot. Also my drive list won't show in my bios when booted with AHCI enabled.
I'm pretty sure it's not a windows issue since Windows was installed with AHCI enabled. I've also done the AHCI fix on the Ms Support site to no avail.
I do not get an error message on boot. I just get a white blinking cursor after the bios runs.

I noticed on another website that someone said the AMD AHCI driver in Bios 3029 was version 3.1.xxx. On boot my screen says the version is AMD AHCI 3.0.5. I'm not sure if that is an issue or a typo.

Any help would be appreciated.
Thanks!

Solved my problem, though I don't know why it worked. Maybe someone can fill in the blanks for me.

I had to disconnect my other two HDD. Then switch to AHCI and let windows boot on my primary SSD. It created a temporary profile for me. This is because I offloaded my user profile to one of my HDD so it's not taking space on my SSD. I powered down, reconnected my two HDD, powered back up and it booted just fine. I still have my to optical drives in IDE though I'm not sure if it makes a difference.

If anyone happens to know. Why did I have to disconnect my two other drives?
