Hi, I recently had a SSD and 16GB RAM installed in a MBP. After each was installed, the Apple Hardware Test was run and no errors were found. A few times now, though the MBP has crashed with 3 beeps. Reading around it sounds like this could be a logic board issue? Am I correct? The AppleCare runs out in 3 days so I need to take it in for service ASAP if this is the case.
