Please Help: Black Screen

Hello,
I am relatively new to WordPress and I am running a blog located @ http://www.footballersempire.com/. Everything was going smooth until last night. Either my theme or one of the plug-ins I installed caused my entire screen to go black. When I log into the dashboard I can update and work as usual however, when I visit the URL http://www.footballersempire.com/ the only thing I can see is a black screen. Does anyone know how I can fix this?
