facing issues while uploading programs on Arduino to breadboard

I am trying to upload a program on Arduino to Breadboard. Bootloader is already burnt. Earlier few times I have programmed it with the same process without any issue. But now I have tried it several times but with no luck. PFB the details:

  1. Operating System: Windows
  2. Board : Arduino Uno
  3. Earlier I have uploaded programs without any issue. I haven't updated any software in my laptop.
  4. Error messages I got:

Arduino: 1.8.5 (Windows 7), Board: "Arduino/Genuino Uno"

Sketch uses 22610 bytes (70%) of program storage space. Maximum is 32256 bytes.
Global variables use 1194 bytes (58%) of dynamic memory, leaving 854 bytes for local variables. Maximum is 2048 bytes.

avrdude done. Thank you.

Problem uploading to board. See http://www.arduino.cc/en/Guide/Troubleshooting#upload for suggestions.
