  • a lot of time is in "storahci.sys!AhciPortBusChangeDpcRoutine".
    storahci.sys is the Micrsosoft default SATA driver, so you should try installing the correct driver for your chipset (for Intel this would be iaStorA.sys)

  • Hi Jukebox461,

    As EckiS pointed out, please ensure you have got Windows 10 compatible drivers for your device. Download the Windows 10 compatible drivers from the device manufacturer website.

    Best regards

  • Hmmm, I can see that it is the "Standard SATA AHCI Controller" in device manager, but every time I try updating it just says "The best driver software for your device is already installed".

    I have an AMD A10 6800k @ 4.4Ghz and my MoBo has an A88X Chipset.

    Nothing special with my HDDs. 2 oldschool Sata 3's at 7600RPM, and an SSD.

    I do have several after-market front-of-case I/O that I've installed. Card readers and eSata outs and Sata outs and whatnot. I think one (maybe two) of those use SATA.

  • contact your mainboard manufcaturer. There should be a "AMD AHCI driver V1.3.1.276 for Windows Win10 64bit",
    for example on the Asus Page for the A88X-PRO
