Have you disconnected the RAMPS shield from the Arduino MEGA 2560 before trying to do an upload?
Hi yes i have when its plugged into usb the green led is on and the orange led next 2 L stays on as well I noticed down the bottom of the arduino ide box its says ARDUINO/GENUINO MEGA OR MEGA 2560, ATMEGA2560(MEGA 2560) ON COM1 shouldnt it say COM3 ?
I think i fixed the problem I was useing the new version of ARDUINO IDE got rid of that and download the old version 1.0.5-r2 and it started uploading so not sure what went wrong with it

It's probably a driver issue. You may still be able to use the 1.6.5 now that your driver is working. Someone else had this issue and fixed it by removing the driver after uninstalling IDE and then reinstalling IDE.
Curious, have you installed IDE 1.7.x from arduino.org?
Hi no I have not download 1.7.x I download 1.0.5-r2 and it started working I just stay with that IDE for now I will later update to the new IDE but I have a mate who wants 2 get into 3d printering but has no idea about Marlin so iam doing all the firmware setup for him the problem i had/have was I uploaded firmware to my about 2 years and had not had much to do with marlin firmware but iam getting there just trying to find the correct settings for marlin hes building the reprap prusa gen2 with the A frames been couple of places if you no of any web link where I can cross check my settings would be cool thanks 2 you for the help .
I've read someone self with this problem had to uninstall the driver from device manager and reinstall it with the one in IDE 1.6.5
I have not had this problem myself though.
