Solution 1 - Repair your StorAHCLsys Driver

According to Microsoft support, the ID 129 events, which are hard disk controller resets, can be caused by a variety of factors. One of them is that some Advanced Host Controller Interface PCI-Express (AHCI PCIe) modes cause this symptom in Windows 10 when running with the StorAHCI.sys driver input.

Due to a firmware error, the solid-state driver (SSD) does not terminate the input / output properly when the MSI mode (Message Signaled Interrupt) is activated. Therefore, the Windows memory stack tries to reset the device after waiting for the unresponsive read / write process for some time.

Therefore, the first solution to remedy "Disk 100% load Windows 10" is to deactivate the MDI mode through the register. Follow the instructions as follows:

First part: Determine whether you are running the incoming driver AHCI (StorAHCLsys)

Step 3: Navigate to "HKEY_LOCAL_MACHINE \ System \ CurrentControlSet \ Enum \ PCI \ \ Device Parameters \ Interrupt Management \ MessageSignaledInterruptProperties“Where <AHCI controller> refers to the device instance path mentioned in step 1. Then change the value of the MSISupported key from "1" to "0".

Restart the computer and check if it works for your computer.

If this provider can't offer you any help, then don't worry. Microsoft has its own standard anti-malware called Windows Defender.

Solution 8 - reset virtual memory

Virtual memory is a part of your hard drive and is seen as an extension of the physical storage space on your computer. If there is insufficient RAM to carry out a task, Windows temporarily saves the files in virtual memory and swaps them back to RAM if necessary. Improper virtual memory could cause high disk usage in Windows 10.

Here is the procedure on how to reset the virtual memory.

Tip: (1) Initial size: This value depends on your computer. If you're not sure which number to enter, just enter the recommended number.
(2) maximum size: We recommend that you set this value to 1.5 times your physical memory. If your PC has 4 GB (4096 MB) of RAM, this should be more than approximately 6.144 MB (4096 MB x 1.5).

Then click on "Set" and then on "Ok" to continue.

Step 5. Now is the time to clean up all of the temporary files on your PC. Press "Win + R" to open the execution dialog. Then type in "temp" and hit Enter. This is how Windows Explorer will refer to the folder for temporary files.

Step 6. Select and delete all files in this folder.
