I have a Dell Inspiron 3552 that came with ubuntu 14.04. I used the updater to get updates (hoping to get 16.04) and when I restarted the computer, following the prompts, it still showed version 14.04 and Chromium no longer works. how do I get the 16.04 version and should I scrap Chromium and download another browser?

You will not upgrade to a new release this way.
The correct command is do-release-upgrade
.
Also I don't recommend to upgrade a pre-installed Dell Ubuntu 14.04 to 16.04. It causes lot's of trouble in many cases.
The recommended way is to do a fresh install of Ubuntu 16.04.
Regarding Google Chrome and probably other Chromium based browsers, they don't support 32-bit systems any more. You can use Firefox.

As with any major operation, the first thing to do is backup any data you can't afford to lose. Although problems are rare they do occur.
to check which version will be applied, open a terminal and do:
sudo do-release-upgrade -c
to make it easier on the dependency resolver, be sure your current software is up to date:
sudo apt-get update
sudo apt-get upgrade
sudo apt-get dist-upgrade
next clean up apt:
sudo apt-get clean
sudo apt-get autoremove
now you are ready to upgrade:
sudo do-release-upgrade
the installer should give a list of actions it will perform. read over the removal list carefully before committing to the upgrade.
