    How to track down missing device drivers?


    I have just done a Clean Install of Windows 10 on my Sony Vaio VGN-NW21ZF laptop following a partition corruption while trying to repartition the HDD. previously it had been upgraded to Windows 10 from Windows 7 and there were no device driver issues.

    All appears to be working OK, but in device manager I have two unknown devices that do not have drivers installed. On is described as Base System Device, and the other as Unknown Device. Looking at Sysyinfo I see the following details:

    Problem solved - I found the Drivers folder from the last full backup before I did the reinstall and successfully installed the drivers from there.
