[Arquivado] Tela "azul da morte"

Olá.

Não tenho bem certeza de que estou postando na categoria certa (caso esteja errado por favor me conduza ao assunto correto)

Meu computador está apresentando lentidão fora do comum e em alguns momentos aparece a TELA AZUL DA MORTE dizendo que ocorreu um erro grave na memória (qualquer coisa parecida com isso) e eu não sei mais oq fazer... já passei antivirus, antispyware, antimalware, passei a verificação de erro na inicialização, limpei o disco, limpei os logs, restaurei o sistema para uma data anterior para tentar corrigir uma eventual alteração indevida, e mais um monte de coisas mas o problema não é resolvido. Podem me ajudar? Por favor!
