Hi Bill,
thank you so much for the link. Unfortunately I can't upgrade my Dell, it's no longer working ( I think it got overheated, after I accidently left it switched on) it sort of went into meltdown, and I haven't had a chance to see if it's repairable. I'm actually planning on replacing, so your link will come in really handy.
Thank you for the offer of help. I'll do a bit of reading and see if I can make sense of it.

best wishes
rikki
