A fresh install and clean up?

My upgrade to 12.04 seems to be slow and there seems to be something that is sapping my system resources.

I have no data on the machine - everything is in the cloud including Xmarks bookmarks for Firefox.

Is it best to do a clean installation? If so, how do I do it?

Thanks John.

Put the instillation disc in your computer, you can get an image from http/ when the disc loads select install, the select erase disk and install Ubuntu and you will be guided though the rest

Thanks very much Sean! – John Newton May 7 '12 at 11:45

In addition to the above, I would add that if you are on a dual boot system with Windows, check that you are not using a wubi installation and that you are booting from the disk and not running it from Windows.
