Welcome to the CentOS fora. Please see the recommended reading for new users linked in my signature.

Removing and reinstalling is not likely to help with a configuration issue. Have you tried googling the [url=MySQL "ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: YES)"]error[/url]? Seems to be a rather common problem.
