We finally figured out the real issue. The HTC Vive 3-in-1 Cable is bad. I had to order a new one because HTC Vive would not honor their warranty again, even though this problem started happening over two (2) months ago. The issue was this 3-in-1 cable all along, but since it took so long to troubleshoot it, my warranty has since expired, so HTC Vive will not honor their warranty.
We did not even open the boxes containing the HTC Vive VR System until my kids woke up Christmas morning, 12/25/2018. So, my warranty should actually still be in effect today because we have not even installed and used it for 1-year yet.
Special thanks to HTC Vive's excellent troubleshooter named Jeisson! He was brilliant in how he figured this out, and he was able to confirm it to be the actual issue. He stuck this one out to the bitter end.
I hope this helps others here, who could very well have this same issue. During these past two (2) months of troubleshooting, I have seen many people online who are getting the same errors and symptoms, so please ensure you check this 3-in-1 cable issue out in depth.
