Hi, Recently my laptop won't open any programs. Skype, Itunes, Steam, they just won't open. Firefox / Internet Explorer are the only ones that work but they can't play flash files without crashing. When I right click steam in add / remove programs and click repair it tells me the file is "on a network resource that is unavailable" or something. Could this have something to do with recently Defragging? Nothing like this has ever happened before. I can't access my music or any of my games Please help if you can, it would be GREATLY appreciated!
