I understand about the issue with a new and different OS,what I can not get my mind to understand is why the first time runs and then not. Then I found one solution and it works. And in the next day the problem returns. And now,the first solution does not work.
Every time I get the black screen I have to terminate my user session or reboot the pc,because I can't do anything.
If it worked one time,why it does not work again?
