I have an iMac7,1 Intel core duo using OS10.4.11 which is now quite dated.

Can I upgrade to the latest OS? If not, to what level can I upgrade.

If I clean the hard drive completely, can I install Snow Leopard or Lion or Mountain Lion?

An iMac 7,1 would have a core 2 duo, not the core duo chip.
If it's the core duo, then what you have is the 6,1 iMac.

Apple says the 7,1 is capable of running 10.8, although, I wouldn't unless you put at least 4 GB RAM in it.
The 6,1 is not.

To get there, you'll need to order Snow Leopard from Apple - $20 shipped in the U.S.
Not sure what the price is in the UK.
That machine, I might be inclined to keep it at Snow Leopard.
To get to ML though, once you have SL installed, grab and run the 10.6.8 combo update to update the machine, then you'll have access to the app store to purchase 10.8.

upgrading 10.4.11

Thank you - that's most helpful. You are quite right that it has Intel core 2 duo. I'll explore availability of upgrade software in the UK.

Now I have to ask how I increase memory from 1GB to 4GB !

I've backed up most of my stuff but assume that upgrading should not affect folders and files on the hard drive.

(One of our daughters is married to a Texan and living a mile away from West. The fertiliser plant explosion rocked them. It must be true that things are bigger in Texas.)
