Very dead as diagnosed by our Moderator here Al, an Apple service agent & Apple tech themselves.
Dead logic board
Faulty CD drawer
£500 + to repair
That's just £300 short of getting a new one...
But I like this one, especially "my life" which is on it's hard drive (confirmed as undamaged)
So I am having it brought back from the dead....
I get it back any day now....
