    Try using the old version of the Arduino compiler (1.6.9 or earlier).
    However that usually indicates a bad arduino.

    Assuming that the Ardunio is actually ON COM3... You need to verify that.

    It is on com 3, so you think its a bad arduino?

    That error is usually from a bad arduino or a bad cable connecting to it from the PC.

    The avrdude errors are all generated by the Arduino core.
    If you google

    "avrdude: stk500v2_ReceiveMessage(): timeout"

    (for example) you will see things like this:

    That is a situation where I would (because I tinker) try to reload the bootloader* on the arduino after swapping in a new one.
    You might be able to recover it that way, but likely bad hardware on the board. I am not going to bother to repair a Mega given the cost of clone boards, but occasionally this sort of thing can be cured by a bootloader reload. In your case I would say replace it and if it works when you reload the firmware throw away the old one.



    *not a simple process, requires a bit more hardware.

    Make sure you are using a new decent USB cable.
    That can cause all sorts of grief.
