Hi

My Arduino Mega ADK was powering up and working fine until now .
When I give USB power (standalone board without anything connected to it) , the polyfuse next to the USB becomes very hot , the main ATMEL chip becomes warm and the LED light fades away and shuts down the arduino.
The 5v pin also doesnt give me 5V and instead 3.4 V (approx) when i checked with the multimeter .  Could you tell me how to fix this issue please .
