[ubuntu] New Install on Windows 7 Machine

I have recently installed Ubuntu 12.04 LTS on my laptop from within Windows 7. I set aside 30GB of the hard drive for Ubuntu.

The issue I am having is that Ubuntu runs extremely slow. It sometimes takes around 90 seconds for Firefox to open or for the software center window to open.

First thing I tried was uninstalling Ubuntu and reinstalling but I have the same issue still.

Any help and/or suggestions much appreciated.
