Raspberry Pi Won't Start

Assuming you can get it booted up, is there anything in the log files?
To me it sounds like you have a bad power supply, bad usb cable or both. Without a proper load meter to test, it's hard to detect. Have you tried a completely different power supply and cable?

No...

Maybe there are no more sensible suggestions left to be made?

If the RPi shuts down because the Power indicator has gone out, chances are enormously high you have a power supply problem.

You really need to identify what went wrong with the borken Raspberry or you'll buy a new one and it will die in exactly the same way when you make the same mistake again.

Is it cruddy power supply?
A useless cable between power supply and Pi?
Bad, fake or burned SDCard?
GPIO abuse?
Polyfuse abuse?
Mutilated or missing circuit board components?
Something else?
