Hehehe, found my solution.
In another forum, a user posted that he noticed WordPress is trying to load all his scripts all at once and he believed that may have been an issue but another user posted:
"Script concatenation in admin area is normal behavior, but I am not sure that trying to load that many scripts is.
You can disable concatenation by defining CONCATENATE_SCRIPTS constant to false (in wp-config.php would be fitting)."
I added this line:
define('CONCATENATE_SCRIPTS', false);
to my wp-config.php file and now everything is back to normal :)
