I turned on the sick computer and when I got the logon screen, the little symbol on the lower right showed I didn't have a wifi internet connection. When I clicked on it, it said it could not connect. I thought that maybe I'm still in Diagnostic startup mode. I also had an alert in hidden icons next to the Avast saying I was unprotected.
When I entered msconfig, the general tab showed that I was in Selective startup with load system services, load startup (both checked) and use original boot config (pre-checked and grayed out.)
I tried to change it to normal startup and restart, but msconfig took me back to where I was with the selective startup. Should I follow your instructions while in selective start up about hide Microsoft services and unchecking items. Some are checked but stopped. I think it looks the same in Safe mode. I couldn't access the internet in safe mode either. It said server could not be found. Do I need to keep the Intel and Toshiba items? I assume I have to keep things that have to do with my Logitech wireless mouse. What else has to do with networking? My printer?
