UPDATE-RESOLVED
After trying all of the last 6 things to try to no avail, I decided to start over. I put in countless hours trying
to resolve these issues & decided to give up. I installed windows 7 followed up by Windows 10 & now
all seems to be working. I get a full screen, able to get online wirelessly with no problems as yet. Have more things to do yet but hopefully they will be troubless. Thanks again for all the help & a Happy Holiday to all.....
