You are running an old now unsupported release of Ubuntu.

I would strongly recommend you backup your personal data install either Xubuntu:
http://xubuntu.org/getxubuntu/
or Ubuntu
http://www.ubuntu.com/download/desktop

and restore your data from the backup. This will give you the cleanest system.

Alternatively if you want to try an upgrade instead take a look here:

I also suggest performing a clean install of Ubuntu 12.04 LTS, which is supported until April 2017.

Oneiric is EOL and no longer supported in any way. I suggest an upgrade online or clean install of Precise. It is LTS and supported til April 2017

Can you help with this problem?
