Hi, Danny & welcome to the WordPress support forum.
Firstly, where did you install WordPress, i.e., to the root of your site or to a separate folder?
2nd, might we please see a copy of your .htaccess file?
3rd, please examine your wp-config.php file to ensure the database details are correct. Your password is likely in an encrypted form, though, so don't change that.
Awaiting your reply.
