So I was playing my Sims game and when I went to save it..it froze. I hit the restart button after tryin everything else. It didn't restart at all it just went to a black screen..I can't turn it off..the disc drive isn't spinning and wont open. Nothing works. It is just a plain old black screen as if it weren't even on. I tried unplugging it and plugging it back it but nothing will work..someone please help
