In all my previous installations, I purchased the Windows DVD and did a clean install onto a new drive. For my latest, though, to take advantage of the free upgrade (which ends in July), I upgraded to 10 over Windows 8.1 on all three PCs. The suggestion by John sounds good, to make a clean install, but if I'm reading it correctly, your Windows 7 drive will also become Windows 10 first. Then you will quickly know if your specific problem has been solved.

By the way, I just reinstalled a Windows 8 OEM PC. The updates took Microsoft several days to complete, on and off; every time I booted, it told me to wait... The upgrades to Windows 10 were all done over a year ago, but as I recall, the whole process was much quicker and done in one shot.
