The hinge has bust on my laptop. I've taken the plastic apart and the metals snapped inside

Basically can it be fixed or is it toast? its about 6 years old and getting s-l-o-w, seems to get hot very quickly and is constantly chucking the message up about increasing the virtual memory. Recently had the hard drive replaced so don't want to keep throwing money at it if its way passed its best. Its a Toshiba Satellite A40 it helps anyone.
