Arduino getting hot whenever I am plugging it to PC

Hello, My arduino is getting hot whenever I am connecting it with PC I dont know the reason but its getting really hot in matter of seconds especially this chip illustrated in image

The small chip directly after the usb |281x500

The board is broken. :( The chip is ATmega16U2 and it works as USB/serial converter for the main ATmega328P. It is probably damaged and high current sink cause that it is getting hot.

looks like that because my pc now can not see the board

thank you :(
