While working on this I'd recommend renaming the .htaccess file to something else. MODX will work fine without it and it will take that out of the equation.
Try putting this at the end of your test.html file:
It should give you a long page of info about your server setup.
If that doesn't work, your PHP engine is not enabled.
Another possibility is that the rewrite engine is not enabled in you hosting setup. XAMPP installs with the rewrite engine off by default, so maybe EasyPHP is the same.
There's probably a server error log somewhere in EasyPHP that might help.
You can also check the MODX error log file in the core/cache/logs directory.
