My Xbox 360 is unmodded, besides the Xclamp mod, and playing a store bought original with absolutely no scratches.
My Xbox 360 was giving me the 3ROL a while back and I did the Xclamp mod and this cured it.
My situation seems to be a bit different from what most people are experiencing. When Halo 3 freezes, it is generally in heavy traffic firefights, or grenades in the face explosions. Not always, but usually. NO graphical glitches or anything/no checkered patterns etc... And after it freezes, for about 4-5 seconds I can hear the sound playing. And the strangest thing is that even though the game is frozen, I can hit the Xbox Logo on my controller and I hear the "blip" noise when it comes up.
When I proceed to hit the eject button on my Xbox 360, it takes me back to the dashboard and I am disconnected from XBL. But I can get right back on again and keep playing. I played for 7 hours with it freezing once, but now I can't seem to play 1 hour without it freezing.
My Xbox 360 is out of warranty, and the seal is broken, so MS will not be getting it back.
I know it probably isn't heat related because when your Xbox 360 freezes because of GPU/CPU overheating, you have to shut down and powerup your Xbox 360 to get back to the dash, whereas I am able to just hit eject to bring it to dash.
Faulty DVD laser? Or?
Help is much appreciated
