It seems to me that the most important of my problems should be discussed first since I believe that this particular bootup problem might eventually lead to an inability to be able to access the computer at all. In the past few weeks on bootup I occasionally note that the 3 moving blue "progress" squares halt after they have been moving awhile and the computer is frozen. This requires that I hold the computer's Start/Stop button in for a while to shut the computer down. Waiting awhile and then pressing the Start/Stop button to restart the computer brings me to a text screen offering a start up using 3 types of Safe mode, or using the last good configuration of Windows or simply a regular Desktop bootup. Choosing the last option boots up into what seems to be a normally functioning operating Desktop.
For several months I have been having a set of other bootup and shutdown problems along with some program malfunctions and I don't know whether these are interrelated or not but a community advisor told me that it would be best to present only one of these in a specific question rather than giving the entire set. I have detailed documentation and images of error messages if these are requested.
