Hi Lee,

Sorry for the late response, but I have been thinking about this - could it 
be a hardware problem ?

Did you change/upgrade anything before this happened?

I have had parts on my motherboard break before.  They were all still 
available etc, but just no longer work.

I realise it's not a good solution, but maybe adding a different video card 
might be a simple solution.
It would at least give you an idea whether the problem is hardware related.

cheers,
