When uploading any code to Arduino nano v3, i got this. Someone have answer?
Does your hardware pass the Loopback test, posted at the top of this forum?
Does your FTDI driver show up in Device Manager with a ! over it?
im having the same problem with my Bord
please may you help

Did you try the loop-back test as instructed above? IF so, what were the results?
I made loop-back test, and my computer start to sound unplug and plugged repeatedly and i didn´t got any data back.
Do you mean FTDI as COM ports? I have my arduino at (COM4) port and it´s free port.

yes, there is a FTDI chip on-board the Nano which provides the comport through which you communicate with the board's micro-processor.

The above suggests that might be having connection issues, have you tried using another USB cord?
I have tried with another cable and computer, still not working...

Okay, do you have access to any other Arduino Boards?
The fact that you were failing the loopback test indicates that there might be a problem with the FTDI device or its drivers.
I have Arduino Uno R3 and Nano v3, both worked, untill i broke them..
I connected them accidentally to 12v solenoid, and then i couldn´t write anything to them. But they are still running with that code i was uploaded to them, but i can´t read or write them.
I´m sorry that my language skills are so bad.... Finnish guys don´t speak English often 
Alright the fact that they are still running the sketches that were uploaded to then previously means that the "processors" are still somewhat functional. Connecting them to 12 volts directly however could have cause damage to a lot of different components on each board.
I would suggest you try to upload to the boards through a separate USB-Serial device if you have one. That might return some use of the boards. Sadly there is no sure way to tell what got damaged on the board.
P.S. Just a bit curious, can you recall which pins you connected to 12 volt?
I connect PD3(Digital pin 3).
I hope at new Arduino(some new model) include fuse because i have broken too many boards.
