Yes, yes, YES!!! Got it. Thanks to all who helped. Somewhere, somehow I think I screwed up a password between MySql and PHPadmin, which I attempted to fix (successfully I think) by editing in php config file. Then I created a new user for the database wordpress in phpMyAdmin, and tried to straighten out all the pathways and usernames, passwords etc. Somehow, like making sausage, it worked. Only it was like making sausage using a german recipe and a german/english dictionary.
WordPress is now functioning on my computer.
Thanks again for all the tips
