I have recently purchased a used MacBook Pro 2012 model. It was working fine with 4 GB of memory. When I upgraded it to 8GB by installing single Samsung sim also it worked fine. But once 5he technician was gone it started giving problems in the sense that it is not booting most of the time and it boots only some of the but after a few minutes of use it shuts down. Kindly help.
Got a tip for us?

Sounds like the the RAM isn't inserted properly. But it could be defective RAM, but either way you're going to have to open it back up.
