Hola, mi problema es el siguiente: se me apaga el pc de repente sin avisar, primero se cierran los programas y mas tarde se apaga, aunque hay veces qe se apaga directamente, esto lo hace muy a menudo, y no se si es por un virus o algun otro problema.
Tengo instalado el ccleaner, el spyblaster, y el SuperAntiSpyware, el cual me dice qe no poseo ninguna amenaza, por tanto de aqui mi desconcierto a no saber que hacer.
Aqui les pego mi log, a ver si ustedes saben que le puede ocurrir.
Muchas gracias y felicidades por el foro.

Ahh, se me olvidaba, despues de que el ordenador se me apague, al volverlo a encender me dice qe windows no se apago correctamente....(no creo que el dato les ayude mucho), pero en ocasiones al volver a encenderlo se enciende y a los dos segundos se vuelve a apagar, no llega a salir ni el simbolo de vaio.

Muchas gracias y espero que me ayuden.

Nadie que me eche una manita???

Gracias.

He vuelto a pasar el ccleaner y el SuperAntiSpyWare y el resultado del log es este:
