Hi,

Have Ubuntu & it was working well, but has become slow, 'greys out' on me regularly - eg. pic loses colour & nothing will respond for a few or more seconds. Also 'Ubuntu Software Centre' & "Synaptic' thingy come up with errors, saying can't install or uninstall progs.... altho it seems they may do it OK despite saying they can't. Have Computer Janitor installed, but this is no longer working at all.

So... is there a program or such that I can use to test/clean out the system?? For that matter, is there a program for testing hardware, as I'm not sure if it's an indication of unhealthy hard drive or such??

You may not need any special program to test the system. Instead start by trying to understand the errors that different programs are
reporting. For example please post the exact error messages you get from synaptic.
