U R better off 2 get a new one

1. You need to be able to open up the NBs and reach the CPU without damaging the shell.
2. You need to be able to remove both NBs' CPU, which I believe most if not all are soldered to the mainboard.
3. You need to find out if the socket will accept the new CPU after figuring out what model your mainboard is.

Good luck, pal!
