4 Solutions Help You Quickly Resolve SSD freezing Windows 10

Solution 1.Check If the SSD Is Connected to the SATA 3 Port

Windows 10 SSD freeze may be caused by connecting the SSD to the wrong SATA port. SATA 3 has transfer cap of 6 Gbps and SATA 2 has transfer cap of 3 Gbps. SATA 3 devices can be used with SATA 2 port. But when you connect a HDD or SSD from SATA 3 to SATA 2, the read-write speed will reduce and your SSD won’t work up to its potential, which may lead to the annoying SSD freezing up.

So you need to make sure that your SSD is connected to the SATA 3.0 interface of the motherboard (except M.2 SSD). If the previous generation of SATA 2.0 interface is still connected, the performance of SSD will be severely limited. You may replug your SSD into the SATA3 port to see if that works.

Solution 2. Enable the ACHI Mode

AHCI (Advanced Host Controller Interface) is a new mode for memory devices, in which a computer can use all SATA advantages such as higher speed of data exchange with SSD and HDD as well as hot swapping of hard disks. When you enable AHCI mode, the speed of access to files in memory devices will be increased and overall performance of your computer could be improved.

The current mainstream motherboards basically enable the ACHI mode by default. However, for a few motherboards, as well as the previous old motherboard, the default IDE option should be manually changed to ACHI option through BIOS settings, otherwise it will affect the speed of SSD.

To enable AHCI, you’ll have to enter the BIOS of your computer and enable it somewhere within its settings. It’s most recommended that you enable this feature before installing the operating system, but in this case, your SSD freeze may be caused by AHCI mode not enabled, which indicates that you may not enable ACHI mode before installing the operating system to your SSD.

Indeed, it is quite possible that AHCI mode is already enabled in your PC. You might wonder: how do I know which mode the computer’s controller is using? No need to worry. Here I will offer you a method to help you find out.

Step 1. Right-click Window Start menu and choose Device Manager.

Step 2. Open the section IDE ATA/ATAPI controllers.

Step3. If there is a device containing AHCI in its name as you can see in the following picture, it means that AHCI mode is used in this computer.

find Standard SATA AHCI Controller

Warning: What you need to pay attention to is that if you just enable AHCI mode in the BIOS setting after Windows installation, your system might refuse to boot, getting stuck in a series of restarts. That is why it is recommended to enable AHCI before installing Windows.

If you do forget to enable AHCI mode for SATA on a computer where Windows is already installed, then it could be a reason for Windows 10 SSD freeze. In this case, you may follow the steps as below to enable ACHI and Windows will work normally. But you would better backup important files and data in case of any unexpected mistakes causing data loss during these operations. Now follow me to learn how to enable ACHI mode for SATA when Windows is already installed.

Step 1. Right-click Windows Start menu and choose Run. Then type in the command regedit to Registry Editor.

Step 2. Open the section HKEY_LOCAL_MACHINE SYSTEM CurrentControlSet Services iaStorV

Step 3. Double-click on Start element and set its value to 0 (zero).

Step 4. Open the section HKEY_LOCAL_MACHINE SYSTEM CurrentControlSet Services iaStorAV StartOverride and set the zero value for the element 0.

Step 5. Open section HKEY_LOCAL_MACHINE SYSTEM CurrentControlSet Services storahci. Then double-click the Start element and set the value to 0 (zero).

Step 6. In the subsection, HKEY_LOCAL_MACHINE SYSTEM CurrentControlSet Services storahci StartOverride set the zero value for the element 0. You may see nothing if you has enabled ACHI. But if AHCI has not been enabled yet, you will see it.

Step 7. Close Registry Editor.

Step 8. Restart the computer and enter UEFI or BIOS. In UEFI or BIOS, find SATA settings to select the mode for memory devices. Switch them to AHCI, save settings and restart the computer. For the first time after the restart, it is recommended to boot Windows in safe mode.

After the restart, Windows will start installation of SATA drivers, and when it is over, it will ask you for another restart. Do it, and AHCI mode in Windows will be enabled.

Solution3. SSD Freezing Fix by Checking 4K Alignment

4K alignment is one of the important factors that impact the read-write speed of an SSD. If SSDs are not aligned at 4K, the speed of the SSDs will be seriously affected, and the extreme switching and fluency experience will not be experienced. This could be a reason causing SSD freeze-up.

When you migrate your Windows OS from a mechanical hard drive to a solid state drive, your partitions may not be correctly aligned. This will lead to SSD freezing, slowing down your computer performance. But don’t worry, to make 4K alignment of an SSD is very simple by using an third-party software MiniTool Partition Wizard.

MiniTool Partition Wizard is an all-in-one partition management tool that helps you manage disks and partitions in an effortless way. For example, with the assistance of MiniTool Partition Wizard, you can not only align partitions on an SSD, but also format partition, move or resize a partition, convert MBR disk to GPT disk and so on.

Tip: Please note that all the data on the SSD will be destroyed, so make sure you have made backups in advance if some important files are saved on the SSD. If it s a brand new SSD and it can hold all data in the source disk, then you can use it directly without backing up anything.

Step 7. Review the changes you are going to make on the SSD. You may also change the copy options by yourself if necessary. And you can also change the partition size by dragging the handle bar. Then click Next to continue.

Note: 1. Fit partitions to entire disk: the whole SSD will be taken up proportionally by the partitions to be copied.
2. Copy partitions without resize: each partition size will be kept as they are on the source disk. This option works only when the target disk is large enough to hold all partitions on the source drive.
3. Align partitions to 1 MB: when the target disk is an SSD, checking this option helps to enhance SSD performance.
4. Use GUID Partition Table for the target disk: this option will turn the target disk into a GPT disk. If you want to clone MBR disk to GPT disk, you check this option. But what you need to know is that this feature is only available on a paid edition if you want to convert the system disk to GPT disk.
