Falha no hardware do meu MacBook Pro (13 polegadas, meados de 2012)

Na última terça-feira, meu computador travou durante uma reunião do Skype, congelou, a tela ficou preta e três bipes começaram a soar em série. Pesquisei o sintoma no Google e descobri que estava relacionado a um problema de verificação de paridade de memória. Na quarta-feira, removi o DIMM ofensivo (deixou 1 "bom" ainda funcionando) e o computador parecia funcionar bem até hoje, quando o sistema travou duas vezes com uma tela branca com um erro genérico de travamento em vários idiomas. Tentei o teste de hardware da Apple (ainda não o extenso), mas não relatou problemas. O OSX armazena logs de falhas que eu poderia ler e / ou compartilhar com você?

Qualquer sugestão sobre o diagnóstico de uma possível falha de hardware seria apreciada.

Atualização 22/05/2017: O sistema travou e reiniciou, com a seguinte saída:
