AHCI controller problem

[simon5413]

I have a 5,1 (converted from 4,1) MacPro that for three years has been successfully using a generic SATA host card for extra storage. In December I experienced a variety of weird failures across my various systems (hard drive dead here, UPS dead there), and around that same time this host card stopped recognizing any attached drives. I'm at the point now where I think the driver itself might have been corrupted some how and I'm wondering if anyone knows how to reinstall the specific driver it uses (which is built-in to OSX). The card is still seen in the system report as there and has the driver installed.

Troubleshooting I've done that hasn't changed the situation:

Swapped PCI slots
Bought a new host card (and tried in different PCI slots)
Bought a new SATA enclosure
Tried a third enclosure
Tried different SATA cables (on all enclosures)

Does anyone have any suggestions? Or know how to reinstall the AHCI controller?

I have tried uninstalling it but it still shows

How can i get rid of that message ,and just boot as normal?.I understand a lot of people have the same problem.This is on Windows.I was going to try on another slot.I thought it would be straight forward .

This is the answer someone gave in a forum about it.

*I solved the problem by disabling the CMSs (Compatibility Support Module) in the UEFI options of my MoBo:* i have no idea how to go about doing it.
