This is from dictation.
Here are some general observations about how I have sometimes isolated problems that are hard to understand. It helps a lot if you have another computer available to try things on another computer. In a few cases I have found that there are incompatibilities with some types of Paris feels or even sometimes a failure of an internal component that interferes with proper operation of the computer.
One trick I have often used is the use of some type of partition manager or partition repair tool . I would create a new partition and then install an operating system on the new partition with a minimum set of external devices connected . Most often this would make it immediately clear there was something wrong with the way the original installation was working and then I would have the choice of either trying to repair the original installation or go ahead and use the new installation I had just created. If a person has a good backup scheme to some type of external storage, then disk space should not be an issue. If you make it a habit to back up stuff you don't used to in external storage, then you always have enough free disk days to experiment with a dual boot operating system.
Of course, this is my preference. Others will disagree with me and say it's a waste of resources to have a dual boot operating system just because you want to do some analytical diagnostic studies once in a while. But for me, it's much more convenient to be able to use my own computer as a diagnostic tool because it has more than one operating system. Anyway, that's the way I'd do things and I thought I would just share it with you in case of you're interested in the idea.
A good alternative to this is to make a USB flash drive into a thing that Microsoft calls" Windows to go". When properly licensed, it is a legitimate way to have a truly portable operating system that you can use to test any Windows-based computer that is having difficulties. For more information about that, you can do the Google search on the expression:
Windows To Go.
Ut works best if you have of fast flash drive with at least 16 GB of space.
Just my two cents worth. Microsoft
