programs won't open/norton won't launch
Trying to help my son with his computer, Dell Latitude E5530, running Windows 7. Within the last week he reports computer taking longer and longer to boot up and open programs. I have reset to a restore point a month ago, with no changes. I have reduced the number of programs running at startup with no effect as well. Norton will not open in normal start up. In safe mode, Norton gives and error message. What should I do next?
