The IDE says my (brand new) Arduino UNO is on COM 1 I recently bought an Arduino Uno and installed everything necessary. I tried it on both USB ports on my computer. However, the Ports menu only shows COM1. There is a line on the bottom of the IDE which says Arduino Uno on COM1. 

Any program I try fails to upload to the board. When I tried the Blink example, the following error message appeared:

Arduino: 1.6.3 (Windows 7), Board: "Arduino Uno"

Sketch uses 1,030 bytes (3%) of program storage space. Maximum is 32,256 bytes.

Global variables use 9 bytes (0%) of dynamic memory, leaving 2,039 bytes for
local variables. Maximum is 2,048 bytes.

avrdude: stk500_recv(): programmer is not responding

avrdude: stk500_recv(): programmer is not responding

and so on. Until,

This report would have more information with
"Show verbose output during compilation" enabled in File &gt; Preferences.


I have a Windows 7 64 bit desktop.

Any help will be appreciated.
Here are a few troubleshooting tips:


First check if the board is listed as Arduino Uno in the IDE by going to Tools --> Board
Check this site.
Also, try reinstalling the driver.
Check your cable.
As a last resort you can try re uploading the bootloader.
