Highest Def

When I try to load the site or the admin, I just get a blank white page. In a cruel display of irony, the last thing I was doing was activating a backup plugin and it was taking forever so I stopped it and restarted it, and now nothing... if I look on the server, everything is still there, but i get a blank page.

I just did a google search and everything I am seeing is telling me to do shit in the admin, but my admin is a blank page too!!

Someone please tell me there is a simple explanation and fix???
