I some cases I had a similar problem and here is what I did to find the problem.
Open the index.php in the public_html folder (or your docroot folder) and inster the following code before anything else at the top
Code:
<?php
ini_set('display_errors', 1);
echo "start";
die();
?>
If you still get a white screen then you could have a wrong character encoding as suggested.
If this works then remove the die() and see if you get an error.
I keep moving my echo line further down until I stop seeing it so i know where the error happens
Also check the error.log file if there is anything there that will help.
I hope you can find it.
On the package it said needs Windows 7 or better. So I installed Linux.
