Please forgive me if somebody has already posted about this issue before. I tried searching for it but couldn't find anything. So this is what happened. I put in The Simpsons Game and loaded up my save file. As soon as the level loaded my 360 locked up. I turned it off and when I turned it back on I got the 3 red rings of light. I turned it off and on again a few more times and got the red rings each time. I thought my 360 was dead so I took out my game and just to be sure I tried to turn it on one more time. This time it was fine. OK! So I put my game back in, loaded it up, and once again it locked up giving me the red rings. I tried multiple times to get turn it back on with the game disc still in and it wouldn't work. Sometimes I got the red rings and sometimes I got no lights and the system wouldn't recognize my controller. I took out the game disc and just like magic my 360 booted back up. I decided to try a different game to see what would happen. Everything worked fine. I put the Simpsons back in and that worked fine except for the fact that my save file is gone! I was like somewhere around 75% done with the game and now it is all gone! Where has my save gone and why did I keep getting the red rings and why does it all of a sudden work again? I am afraid to play other games now because I don't want to lose those saves as well. I tried calling the support 1-800 number and after about 20 minutes on hold I got somebody but I got frustrated due to the language barrier and hung up. Has anybody ever even heard of this happening before? Is my 360 on its last leg or maybe my hard drive is going bad? If for some reason the game was trying to autosave when it locked up could me turning it off have messed up my system this bad? Please help me somebody!
