Nenhum despejo parece particularmente conclusivo, apenas listando um problema com "o objeto de dispositivo tem bloqueado um Irp por muito tempo".
Olhando para ele, ambos os dumps mencionam
FAILURE_BUCKET_ID: X64_0x9F_3_e1d62x64_IMAGE_pci.sys
BUCKET_ID: X64_0x9F_3_e1d62x64_IMAGE_pci.sys
onde e1d62x64
é o driver para um adaptador Intel Gigabit.
Eu sugeriria descobrir qual adaptador de rede está em sua máquina (dê uma olhada no gerenciador de dispositivos) e atualizando os drivers para ele para ver se isso resolve a falha.
Uma olhada no primeiro despejo dá a suspeita de BHDrvx64, um componente de driver do Norton Internet Security ou do Norton 360, embora este tópico do fórum faz com que pareça um pouco como um arenque vermelho.

A driver has failed to complete a power IRP within a specific time (usually 10 minutes).
Arguments:
Arg1: 0000000000000003, A device object has been blocking an Irp for too long a time
Arg2: fffffa8006957060, Physical Device Object of the stack
Arg3: fffff8000518b3d8, nt!TRIAGE_9F_POWER on Win7, otherwise the Functional Device Object of the stack

O segundo despejo é efetivamente o mesmo, sem a menção de BHDrvx64
, então não vou repassá-lo.
