Issues Uploading Program to Arduino Nano

Hello! Thankyou for taking a minute to read my query as I know there are tons.

I recently downloaded the Arduino software on my Windows 7 computer and have begun to try and work on some small circuits to get acquainted to the software on my home PC.

My main issue at this point is I am having issues with the program uploading.

I downloaded all of the drivers when I installed the software and am curious as to where I am going wrong.

This is the error message I am receiving.

"Arduino: 1.7.7 (Windows 7), Board: "Arduino Nano, ATmega168"

Sketch uses 3,286 bytes (22%) of program storage space. Maximum is 14,336 bytes.

Global variables use 226 bytes (22%) of dynamic memory, leaving 798 bytes for local variables. Maximum is 1,024 bytes.

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

I dug through the troubleshooting page for quite some time but couldnt find anything about the "programmer not responding."

I have made sure the system board is set to nano and set to ATMega168 but am still having no luck uploading any programs, even with just the arduino plugged into my computer.

Any help with this issue would be greatly appreciated.

Thanks in advance!

What USB/Serial chip is on the Nano? What is the processor chip?
