Wildwood I don't do hardware per se I am however about to learn.
The pavillion is just sitting there so I am going to have a "go" :-) if it doesn't work I will lose a few quid.
I had a major failure and got it repaired but was told told the HD was on its way and I should be looking to replace.
I got a new machine and the old one is now a learning project.
Thanks for all old answers
