Problem for uploading file to arduino board

Hi.. After writing the code I am uploading but it is showing that Uploading to I/O port but not executed . I am not getting output. The code is for a simple blinking program.(taking the Blink Example) What is the problem ? Please Help me

Does it show any errors or say "done uploading" when you hit upload?

Are you using the LED on the board or hooking up an external one?

using LED on board. it is not showing any error and also not saying "done uploading". It is showing uploading.

Your program is not uploading. Are you sure your module is working one? COM port selection is correct?

Also do you see the RX/TX leds flash when you try to upload

Hi... I got it sir :) Actually there is a problem with drive updating.

Good stuff
