we used ARDUINO DECIMILLA[ATMEGA168] microcontroller board.
here on connecting with the usb to pc. pin 13 LED is blinking .
THEN we upload a  blink led programme on arduino enviorment. LED  blinks red.
compile is done.and uploading I/O shows error.
when we remove ATMEGA168 from the board then 13 pin led stops blinking .
So sir i want to know that weathermy Atmega168 is Damaged aur its Driver or another problem...
if it is a driver problem then  from where should i get the driver.

What pin did you put 12V onto? The 5V pin?
If so, you likely damaged the 28-pin surface mount part behind the USB connector - that is a very hard part to replace unless you have special tools.

Do you see the correct serial port in the tools menu?

If not it sounds like you have damaged the USB / Serial bridge chip. They are difficult to replace because you need surface mount rework equipment.
