WP-Config Problems

Okay, I’ll try to make this simple.

I changed my MySQl database password within my Godaddy Account area. Since then I can’t access my website, at all; either as admin or visitor.

Godaddy suggested updating the wp-config file with the new password which hasn’t solved the problem.

As of now I get a 500-Internal Server Error Problem.

This all stems from me trying to get XAMPP working on my Vista PC which is kind of a pain.
