microcontrolller short circuit?!!

[poohpary]

hi...i use an atmega32 in my pcb board..my circuit was fine but i dont know what happened that after turning on the supply for (the last time) micro got so hot . with a multimeter in diode check mode it seems tracks of +Vcc and GND are connected (no power is applied to circuit)...and it seems 3 pads of micro that were programed to be input (i have not used them) are connected to Vcc or GND.so i dont know whats wrong...with micro getting hot can i say that short circuit is done inside of micro? and how can i be sure nothing is wrong with my pcb board so the problem will be solved by exchanging micro?
is there any body to help me plz?!

Assuming that the PCB design is correct and there is no design error connecting the GND with Vcc a magnifying glass can help you check if there is a solder bridge.

just measure voltage in the board before placing any chips
