Also, if you have the Intel Rapid Storage Technology driver installed, uninstall it.

IRST, which stands for Intel Rapid Storage Technology, is a storage driver developed by Intel for use with a variety of storage configurations; such as RAID (redundant array of inexpensive disks) and SATA drives. Modern operating systems such as Windows 10 no longer require IRST driver and can manage such configurations out of the box.

AHCI which stands for Advance Host Controller Interface has been supported out of the box since Windows Vista. If you happen to have Intel Rapid Storage Technology driver installed, you can uninstall it to see if it improves stability. If there is a specific reason you need to keep IRST, then you can try updating it using either the Intel Driver Update Utility or download the latest IRST driver manually and install it. You should check the manufacturers website for your computer model for the latest IRST.

How to uninstall IRST:

Press Windows key + X
Click Apps and Features
Scroll down then select Intel Rapid Storage Technology, right click it then click uninstall.
Best,

If you had a 3rd party antivirus on the OS you upgraded OR if you have one now uninstall it and then run its maker's removal tool. Use Windows Defender which in Windows 8/8.1/10 is a full antivirus. Despite all the hype out there Windows Defender and the Windows Firewall are true superstars.
