Need help as I have to admit I know nothing about macs when they go t ts up can anybody recommend someone who could help me out which live near by (Worcester uk).
Why not tell us what's up in the first place ?. You can easily set a Mac back to factory settings etc with the correct keystrokes on boot up.
Otherwise, post on a MAC forum before you shell out hard earned on what could be an easily solved problem
Cheers,
