I now have my machine working (for the most part). I had to delete all the partitions on my SSD (250GB). The system drive was very full before the install and there seemed to be something wrong with one of the partitions when I went to do a full windows install. I even ran SpinRite (level 2) on it to make sure the SSD was functioning OK, so I was fairly confident that the drive was working.
Now I am in the process of loading all my programs back onto the system. I'll not be installing any large programs on the SSD this time (e.g. World of Warships). I'd rather keep the SSD under 75% full and only have my most critical programs on that drive.
Thankfully, I had everything backed up on 2 other drives as well as cloud backups turned on, so I didn't loose anything other than 2 days of my life (and my stack of Outlook rules to manage my mailbox). Now, if I can remember to get all the backup and other redundant processes all set up again.
