I had to replace one of the video cables (display port) and I had to replace the WiFi adapter.  I attempted to install the Microsoft 365, but failed to do so because of the WiFi adapter was way too slow. Speed was rated below 5.  Obtained a new adapter and purchased a new displayport.  Now I am fighting the issue that I hadn't paid for the Microsoft 365 license because it failed to install properly eariler.  The Product Key was listed as used, when in fact the original installation failed because the WiFi was too slow.  Since I purchased a new DisplayPort cable and new WiFi adapter, the computer is running like a charm.
