Arduino MEGA 2560 Serial port 'COMx' already in use. Try quiting any programs..
about 2 month ago bought arduino mega2560 3d printer construction.
driver installation arduino 0022 easiest thing i've ever done , worked well!! after month of regular working calibrate new 3d printer many successful uploads, arduino mega 2560 stopped working without having done on computer. if try upload sketch, error
processing.app.serialexception: serial port 'com3' in use. try quiting programs may using it.
everything worked until when have finished hardware of 3d printer.
from started mess have not yet solved, , blocking development of project . tried other releases of arduino ide /drivers without success.
i tried w7 recovery point @ date before first arduino installation repeating same steps taken first time installation problem remains.
my computer runs win 7 64bit problem same connecting mega2560 board on w7 64bit computer.
detail: @ power on arduino aref led flashing 1 time still on. on led lit.
the usb serial chipset atmel
i want buy mega2560....but hardware fault?
please can me?
thanks in advance

hi, welcome forum.
this doesn't seem problem have read before.
could remove arduino ide (but not projects folder), , remove java. use javara sure java removed. download zip file of arduino ide 1.5.8 beta , unzip somewhere in folder in home folder. use folder "my programs" or "my apps" that. run arduino folder. remove mega board , connect computer. select mega board, , see com ports available. can tell happens ?
arduino ide 1.5.8 run on 64-bit windows 7 without installing java. perhaps other computer did have java installed ?
did buy official arduino mega 2560 ? if not, might have old bootloader, , should burn new bootloader it.
it possible usb-serial part of mega board broken, i'm not yet sure of that. happens quite little error/problem didn't cause problem in past , cause trouble.
