Reboots much slower after enabling AHCI

Try doing the following:

1. Open a cmd window with elevated privileges (cmd.exe). Type "bcdedit /set {default} bootmenupolicy legacy", without quotes to enable booting options with F8 key at startup.
2. Reboot. Enter BIOS and configure SATA as IDE.
3. Boot Windows into safe mode by pressing F8 before it loads.
4. Open Device Manager to check SATA is actually set to IDE mode.
5. Reboot again. Enter BIOS and set SATA to AHCI mode.
6. Boot again into safe mode (F8). Enter Device Manager and check that AHCI is enabled (even if it's using standard MS AHCI driver).
7. Reboot and boot Windows NORMALLY.
8. If you mainboard uses an Intel chipset, try downloading latest chipset driver from Intel webpage. Install it.
9. Do not install anything else for now (like Intel Rapid Storage thing). Check first if everything is fine.

Okay, will try those things, but when I go to my controllers right now, it is mentioning both IDE and AHCI. Does that mean some drives are using AHCI and others IDE? I do recall before enabling AHCI in my BIOS AHCI did not show up at all in this list.

You might have posted that file here in the thread as well, no problem is there with it; it does not share any of your personal information (other than the username of the computer).

# Well, with 27 statrup items, boot must be slow. IDE, AHCI, SCSI, nothing have anything to do there. And apparently you dont really need anything there other than DisplayFusion. Clean it up, reboot time should be improved upto a certain level.
Follow this guide: Clean Boot - Perform in Windows 10 to Troubleshoot Software Conflicts - Windows 10 Forums

# You have a great lot of storage. But as you have the SSD, generally it is used as the C drive, and the C drive should come first in the disk order. Apparently the 120 GB Crucial SSD is the C drive there, but it is the fourth one in the disk order.

Code:

Model    M4-CT128M4SSD2 ATA Device
--------------------------------------------------------------
Partition    Disk #4, Partition #0 ===> C Drive
Partition Size    118.80 GB (127,561,367,552 bytes) 
--------------------------------------------------------------
Partition    Disk #4, Partition #1
Partition Size    450.00 MB (471,859,200 bytes)

Please arrange the Disks properly. And tally it with the Boot order set into the BIOS.

# This driver ..... I am not finding any reason for it to be there .....

Code:

Name    Asmedia 106x SATA Controller
Driver    c:\windows\system32\drivers\asstor64.sys (2.0.8.0, 82.83 KB (84,816 bytes), 1/27/2014 5:30 PM)

The motherboard supports Intel SATA, which is now managed by microsoft AHCI driver Storahci.sys; Gigabyte SATA (RAID Mode, powered by JMicron), now disabled and managed by microsoft driver; and Marvell RAID (apparently not in use). So I am not seeing a reason for ASmedia RAID driver to be there.

Take care of these three things and let us know the result. We may need to dig further, but these three are the first things to look at.

Thanks for the tips.


My computer gets hung up loading before I even get to the windows logon screen. So I don't think it would be my startup items causing the slowdown, right?

This is the screen it takes a long time loading at: http://fud.community.services.suppor...1-fd438b28f841


How would I go about changing the disk #? I'm familiar with changing the drive letter but not the disk #.


I don't see Asmedia 106x SATA Controller in Device manager > IDE ATA/ATAPI controllers or in add/remove programs. Should I just delete c:\windows\system32\drivers\asstor64.sys and that will fully remove it?

Not right always. Some startup items create the environment in which the OS loads. So the startup items can cause this issue.

Open the computer and re-arrange the SATA cables. All the SATA ports on the motherboard are numbered, follow that numbering. In needed, take the help from the manual. If you dont have it, download it form the board manufacturer's website.


That will disable the driver, but I doubt that the memory resources used by it and IRQ16 will be free from it by doing this.

At the first place, I wonder where and how have you got this driver in your system? How have you installed windows and how have you got the drivers?
The proper and perfect answer to this question will be very important.

I will try and remove a few startups but the thing is all of these were enabled when I was on IDE and it never affected boot speed.

You know what. I have only 2 SATA 3 connectors on my motherboard. They are #3 and #4. That is the reason I believe it is set this way. All the others are SATA 2 and I think that would decrease the performance even more if I moved my SSD to that.

Recently, after I turned on AHCI, I went to my motherboards driver page and installed several drivers that I thought might help. This might be an old one that is no longer needed. How should I fully remove it from the system if not just removing the .sys file?

Also of mention, my BIOS has several areas where to turn on AHCI from IDE. There seems to be a universal section to set IDE or AHCI, which I was successfully able to turn on ACHI to. But for the controller my SSD is on (GSata something) I was unable to turn this from IDE to AHCI without getting a blue screen. I thought maybe the universal section being turned on overrode this section section so I didn't need to pursue turning it on further. Also, when running HD speed tests on my SSD when the universal controller is set to IDE to AHCI shows a clear performance boost when AHCI is on, so I do believe the SSD is still in AHCI mode. I know this might be confusing but I will take a screenshot of my BIOS when I return home from work.

Yes. You are right and this is normal. When there is only IDE, no AHCI entry should appear.
