Minidump de memória RAM - computador reiniciando sozinho.

Question

Boa tarde, Recentemente, meu windows começou a ter crashs. Os crashs são simplesmente desligar e reiniciar, eu gostaria de saber a causa do problema. Nessa última vez que o sistema teve tela azul e reiniciou, apareceu uma mensagem de erro, citando memoria RAM, mas não tive tempo de anotar. No log de erros busquei o relatório desse crash salvo em um minidump do windows. Eu fui atrás desse Dump, mas não sei analizar, gostaria que me dissessem qual é o possível problema, se precisarem posso mandar o arquivo, mas a seguir o dump em texto:

PFN_LIST_CORRUPT (4e)
Typically caused by drivers passing bad memory descriptor lists (ie: calling
MmUnlockPages twice with the same list, etc).  If a kernel debugger is
available get the stack trace.
Arguments:
Arg1: 0000000000000002, A list entry was corrupt
Arg2: 00000000003d7ebc, entry in list being removed
Arg3: 000000000087ffff, highest physical page number
Arg4: 0000000000000001, reference count of entry being removed

Olá, obrigado por entrar em contato com a Microsoft Q&A.

Seus arquivos Minidump apenas indicam corrupção de RAM (memória), e não há uma causa específica para o crash listado.

Para forçar o Windows a gerar arquivos minidump e identificar drivers defeituosos, ative o Driver Verifier e deixe seu PC travar 3 vezes.

Depois disso, desative o Driver Verifier e envie os arquivos minidump recém-criados. Certifique-se de criar um ponto de restauração do sistema antes de fazer qualquer alteração no seu dispositivo.

Veja "Verificador de Motorista - rastrear um motorista que não se comporta" (Artigo relacionado para sua referência)
