I think my 360 has finally failed me. Starting today I was casually playing Halo 3 cause I recently got the legendary map pack(which is pretty cool) when suddenly there was this loud screech that lasted for 1 second then my game froze completely. I thought it was a slight hiccup but when I tried turning it back on... it froze again, then I repeated the same process over and over and it kept on freezing. Then I tried again and it lasted like 15 minutes before it froze again. I saw a bit RRoD occasionally but it never died. But I think its done. I'll try again tomorrow and if does not work then I'm sending it in...
