Meu computador (HP DV6 6060EP) foi devolvido para reparo pela HP duas vezes, mas ainda vem com o mesmo problema. Estou tentando o melhor que posso para ajudá-los a diagnosticar esse problema.
Quando meu computador trava (como aconteceu há 5 minutos), depois de abrir o despejo de memória no WinDbg, recebo o seguinte resultado:

Alguém tem uma ideia do que está acontecendo? Eles já trocaram a placa-mãe e o disco rígido.
Obrigado!
Bem, o despejo completo do kernel não estava fornecendo detalhes suficientes, então alterei as configurações para pequenos despejos de memória.
Após verificar o despejo com o WinDbg, consegui ver que o intelpp.sys estava aparecendo como o culpado, então ficou claro que a causa do BSOD era a CPU.
