Windows 7: BSOD during boot on AHCI mode

BSOD during boot on AHCI mode

My motherboard is a Gigabyte Z68XP-UD3 Revision 1.3, my OS is Windows 7 Professional 64 bit, my HDD is a Seagate 1.5tb, and my SSD is an OCZ Agility 3 60gb.

So i was using Intel Smart Response technology with my SSD for SSD caching, everything was pretty much working fine. The other day i flashed my bios using @BIOS without properly disabling my smart response configuration, which i probably shouldn't have done and i won't do again. When i rebooted, Intel Rapid Storage technology was acting up and when i tried to open it, it said "IAStorUI.exe has stopped working". After that, i uninstalled the program and tried to re-install it, but during the install it said "This computer does not meet the minimum requirements for installing the software." After a little research, i found out that it meant that my bios was set in IDE mode instead of ACHI mode. I am not sure what the mode was before i flashed my bios, but it was probably some sort of raid that it used for SSD caching. When i went into the bios and switched from IDE to AHCI, windows would blue screen after performing a few seconds of the boot logo. I switched back to IDE, and did some research to find out about the "Start" registry in HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\msahci. I switched that from 3 to 0, and windows was able to boot into AHCI mode and automatically got drivers. Then, i tried re-installing Intel Rapid Storage technology. It was able to install, and i rebooted my computer. It blue screened again on the same part of the boot logo as before. I had to switch back to IDE mode to get it working again. Then, i got new chipset drivers from Intel's website, which didn't help. The registry that i changed is still set to zero, but it just won't successfully boot with AHCI like it did the first time i changed the registry. I am very stumped and i dont know what i could do to make it work like it did before i flashed my bios. My friend recommended that i should reinstall windows, but then i would have to go through the trouble of getting everything back and i think there should be some way of doing this without reinstalling the os.

Thanks for reading all that. The bottom line is that windows blue screens when the bios is in AHCI mode, even though i have the registry that should fix that and that did fix it on one boot set to zero.

Try to read the error code or name and see if you can get the dump file from the disk...
The files of interest are C:\Windows\MEMORY.DMP and anything in C:\Windows\MiniDump.

Given that the crash occurs during the Windows Logo there is most likely access to the disk thus a dump will be saved there, and given that the BSOD only shows shortly it most likely is a MiniDump, can you upload the most recent ones so we can analyze them?
