Hi

I have a Macbook Pro (MC374LL/A) which won't boot anymore

I followed the recommended steps in the following link here but wasn't able to obtain any imrovement

1) Safe boot doesn't work

2) Reset the NVRAM / PRAM doesn't work

3) Start up your Mac while holding the C key doesn't work

  The DVD I manage to enter is immediately ejected

On each boot the grey screen lasts barely two seconds before the MBP switches itself off

Any ideas ?

thanks

Try booting in verbose mode by holding down command-v and make a note of any error messages.

What happens when you boot holding down command-v? Does anything appear on the monitor at all?

Thanks for all your help and suggestions

Finally, I took the logic board out and cleaned the large amounts of dust,

removed the radiator and cleaned (all) the excess cooling paste

Treated both sides to a clear vinegar tooth brush cleanup

Reassembled and, guess what ? It works !!!
