Hi, and welcome to FineTunedMac. smile

Sorry to hear about your problem.

The first thing I'd try is booting from a clone or other external bootable volume, and I'd next run Apple Hardware Test which, depending upon which MBP you've got, is either on a disk or on your machine.

Please let us know how you make out in both respects.

You may get some insight from this thread.
