Did you install Ubuntu 32-bit or 64-bit?
Which version of Ubuntu are you using?
(Open the System Monitor to find these answers if you are not sure.)

Did you upgrade from an earlier version, or is this a clean installation?

What happens when you run Update Manager, press Check and then Install Updates?
