        The guy is not talking about just not getting the ultimate
        out of the
        machine, he has problems such as "tonight it ground to a
        halt, the
        hard drive access light went mad and the mouse stopped
        moving. Then it
        moved in jerks and a variety of windows greyed out and came
        back again
        over and over."  That is a software problem of some sort.
         Something
        is gobbling up his processor or/and his RAM.


    Yes, I agree, and as previously described, I have seen exactly
    this problem, and on what would seem to be a more powerful
    machine. In the first instance, disable Flash and see if that
    stops or reduces the CPU load. In my experience it will. However,
    it doesn't solve the problem, and this is where I came to a halt
    with trying to analyse it. It is likely to be a combination of
    the Flash plugin, Compiz and the physical hardware, possibly one
    that hasn't been identified before, so to get some progress, it
    needs to be documented.

    However, I believe my point still stands: for all the work done
    to maximise compatibility, there are always going to be machines
    that don't play for less obvious reasons, especially at the low
    cost end of the market, and the rule still should be that if you
    want to use a Linux desktop of any kind do a little bit of
    homework. There is the official compatibility wiki but if you get
    the model number of any laptop and put it into Google, someone
    will have attempted to run Linux on it and reported on it.

    Just to update everyone flash blocker didn't manage 5 minutes
    before both Firefox and system monitor  greyed out simply because
    I tried to close the monitor. As I'm typing this email Thunderbird
    keeps greying out and the text appears on the screen up to 45
    seconds after I typed it. (So apologies for any spelling
    mistakes.) Rhythmbox is playing, well stuttering. That seems to be
    the biggest problem, I have noticed flash can be a drain but any
    media playing and it greatly increases the chance that the system
    will halt.


Try starting Firefox and Thunderbird in safe mode. It's Help > Restart with addons disabled in both, and see how if that improves things.

I've switched to chromium to see what difference that makes. I'll try restarting thunderbird and see what happens
