Try to set a system restore point before installing a device driver. This will help if you installed a wrong driver. Problems can arise when your hardware device is too old or not supported any longer.
Nov 6, 2018 - SATA AHCI driver is crucial if you want to install Windows in AHCI mode instead of IDE. AHCI (Advanced Host Controller Interface) makes NCQ.
AHCI makes NCQ along with hot-plugging or hot swapping through SATA Serial-ATA host controllers possible; Vista was the first to offer this feature. The issue with AHCI is it needs to be enabled in the BIOS prior to OS installation; doing so after you have installed the OS will disable the PC.
The reason why is Windows disables the AHCI drivers not needed durring installation. This tutorial will show you how to enable AHCI after you have installed the OS if you didn't already have AHCI enable in the BIOS when you installed the OS. This method will also work for Windows Vista though the default DWORD string value in Vista will be '4' where it will be '3' in Windows 7. As a precaution it would be a good idea to create a 'System Restore Point' before you start this, the tutorial can be found at the link below. Let's get started! 1) In the Windows start menu search box type regedit, right click the entry, click Run as Administrator, enter your user credentials for the UAC prompt, then click yes to open regedit.
2) In regedit navigate to HKEY_LOCAL_MACHINE SYSTEM CurrentControlSet services. 3) In the left pane, click on msahci, in the right pane double click on Start to modify it. 4 ) In the window that opens change the value to 0 (zero), and click OK. 5) In the left pane, click on iaStorV (if there), in the right pane double click on Start to modify it.
Repeat step 4, and go to step 6 below. NOTE: From: 6) Close Registry Editor. 7) Now you'll need to restart the PC and go into the BIOS and enable AHCI. When Windows boots up, it will finish installing the AHCI drivers. 8) You will need one final restart to finish the process after the drivers are installed.
For those with nForce boards, t his method was worked out by and credit for that goes to him, thanks mate! Just to put in here for nForce users, nForce boards do not support AHCI (with the exception of nForce boards that include onboard graphic cards), and also don't send the TRIM command for SSDs. It can do NCQ through its controller though. The JMicron SATA ports do support AHCI, but you'd get worse performance running a HDD through these, than on the normal SATA ports. You can uninstall the Nvidia controller though in Device Manager and install Microsoft's IDE Controller, which can send TRIM commands for SSDs. Head to Device Manager (Open Start menu, type Device Manager), and click 'IDE ATA/ATAPI Controllers', and you will see 3 Nvidia Serial ATA Controllers. Right click one of them and click 'Properties' and go to the 'Driver' tab.
