Hard to tell whether this topic belongs here or in the arena. It's a hardware issue so I'll try here first; it can be moved if the local authorities prefer.

It's a PAL elite model, I got it on 24/08/07, the day that the elite launched in Europe. It's been kept clean and well ventilated. It's been set up in the upright position so it's got improved airflow since day 1.

(Un)fortunately it's not doing the 3 red rings of death. It's locking up when it tries to load levels on Lego Indiana Jones. Any level. Every level. It's not a bad disc and I completed all of the story levels last night; I'm trying to replay them. The entire console stops responding about the time it should switch from loading screen to the level. The only thing I can do is turn it off with the main power switch; it won't respond to the controller and guide button at all. It's done this 3 times this morning; I haven't been able to play the game at all.

This isn't isolated. Two Worlds hung up on me once at a loading pause. Mass Effect hung up on me once during a big loading section. GTA4 hung up on me 3 times during loading screens. After swapping discs the disc tray is occasionally reluctant to go back in when I press the button; I have to give the tray a gentle push. In all those cases everything worked fine after the system was powered off and on.

Does anyone have an idea of what's wrong with it? I'd prefer to avoid Microsoft support until it's unavoidable. Hours spent on the phone to a call centre on the other side of the world is not my idea of fun.
