OK... so now for the embarrassing part
Having spent the best part of the night checking the filesystem, I had the brainwave of trying the HARDWARE on another machine...... hmmmm
worked fine.
Then tried the USB mouse from the mac on the "broken" system..........hmmmmmm
worked fine
Then opened the box and checked the connections off the ps2 port to the mobo........hmmmmmm
CRACKED!
Still, I only paid $100 for the whole box, so who cares, I'll get it a brand new USB mouse tomorrow.
LESSON FOR THE DAY.......................... hardware craps out too!
Good luck guys
