You could try removing your laptop's hard drive and put it in a new laptop unless the hard drive died too. Just make sure that your fan is cleaned habitually so that extreme overheating like this does not occur.
I really want to hope that only the processor died and not the hard drive as well because if the hard drive is dead then all your data becomes unaccessible (as you have seemed to already notice.)
I really hope this comment helps you and I wish you the warmest good lucks possible. I have had to deal with the same thing twice before I got my current computer when I used my old laptop and it sucks to lose all that data, especially years worth of it.
