My x box keeps on freezing - Microsoft Xbox 360 Console

The freezing happens before the red lights.

It happens because the main chips inside the Xbox 360 are losing connection - you need to stop the heat build up between these and you will be able to fix it.

You can either send it in or use a good repair guide to fix it from home.

This happens as the GPU and the CPU are overheating and before the red lights you
can use a good guide to repair it or you can send it in and get it fixed

If you have not attempted a standard x clamp repair example
(remove the x clamp and replace with screws washer
then force overheating of the G.P.U.)

Then chances are excelent that you could have a " repair shop"
simply reflow the G.P.U. than replace the X clamp hardware
with a more robust clamp to keep the G.P.U. connected
Google " Conformal Compression Assembly "

If you have any questions feel free to ask
