That was how I resolved the issues on one of my troublesome devices.
Created an 8.1 image on a second drive
Deleted all partitions on drive c
Disconnected all perpipherals
Removed or disabled in bios all un-needed components (such as soundcard, tuner etc)
Installed basic win 8.1 install
Didn't bother installing any chipset drivers or anything else
Upgraded to Win10 within Windows 8.1 via USB and confirmed activated
Reactivated required hardware via bios (as applicable)
Disabled Win10 updating drivers
Downloaded latest drivers direct from manufacturer (Nvidia, Intel, Quallcomm, Gigabyte etc)
Rebooted into Win10 USB installation media & clean installed Win10
Reintegrated all backed up files etc into the clean installation.
