Computer gets blue screen after switching from IDE to AHCI mode.

I finally made the jump and bought an 850 EVO 250 GB SSD. However I've been reading that in order to get the best performance you need to be in AHCI mode. I built this computer a couple months ago by buying new parts and adding old ones from my old computer. I transferred the hard drive (which is 8 years old I should add) and power supply over from the last computer, but everything else is new. I remember when I was test running it for the first time I got the blue screen of death every time I turned it on, I read up and found switching to IDE mode would make it work, which it did. However now that I have an SSD I have a reason for it to be in AHCI mode. Anyways, I cloned my HDD to my SSD and it works great in IDE, but no matter what will not work in AHCI. I tried unplugging my HDD as well and only running the SSD, but it has the same effect. I mean the SSD is still wicked fast in IDE but its performance hits a max of like 300 MB/s on both read and write speed, and this one is rated at 500 MB/s.

Specs:
Intel Core i5 4690K
Gigabyte B85M-DS3H-A motherboard
16GB RAM
Radeon R9 380
Windows 10

switch from ide to ahci windows 10
Yes there is a way on WIN 10 also ! Go into BIOS set the SATA mode to IDE and boot into system.

Start REGEDIT and look for this line :

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\storahci\StartOverride

Change the 0 DWORD value from 3 to 0.

Reboot, and change your SATA controller to AHCI in BIOS. Now let it boot into safe mode, WIN 10 will install required drivers for AHCI.

Now with a normal boot you will boot into Windows with AHCI drivers.

Note : OEMs (HP, DELL,etc) suggest reinstalling rather than changing, especially with an SSD.

You stand the chance of loosing your install if something goes wrong, and different systems may behave differently.

*leave the old HDD disconnected till all this is done
