Problem with circuit board or user error?

Hi,

I’m hoping to confirm whether I need a new board or not based on an arvdude error that I cannot solve.

I am currently using an Arduino Uno on Windows 10 which I purchased less than a month ago.

The board was working fine until last week. I started experiencing an issue with uploading to the Uno (error message below).

Before posting to the forum, I tried all of the relevant troubleshooting techniques listed on http://www.arduino.cc/en/Guide/Troubleshooting#upload and searched through forums to find any other suggestions people have made, including:

  • disabling/enabling COM3 port
  • using COM4 instead of COM3
  • resetting the board
  • testing with a different USB cable

This problem persists whether I have components connected to the circuit board or not. For now, I’ve unplugged everything and still receive the following error:

avrdude done. Thank you.

Problem uploading to board. See http://www.arduino.cc/en/Guide/Troubleshooting#upload for suggestions.

This report would have more information with

option enabled in File → Preferences.

Make sure there is nothing connected to the RX and TX serial pins, as it is through these pins that the computer communicates with the microcontroller.

Try to open the serial monitor, or another serial terminal program, and send some text, if the RX LED does not flash, there must be a problem between the computer and the USB-serial converter built into the Arduino UNO board, Maybe a driver problem. But if the LED blinks, then there may have been a corruption of the microcontroller bootloader (Atmega328) on the Arduino UNO board.
