En realidad, yo ya publiqué un log, y mi computadora anda perfecto gracias a este foro , pero ahora mi padre me pidió si le podía arreglar la computadora y la verdad es que intenté pasandole el RegSeeker, así también como el Disk cleaner y el antivirus pago de McAfee, pero la computadora sigue teniendo los mismo problemas:

-no se apaga sola, se tilda en la pantalla que dice "Windows is Shuting down" y cuando se tendría que apagar, no lo hace (esto es lo que más me preocupa)

-está muy lenta en relación con el porciento de disco rígido ocupado (menos del 50%)

-se desconecta bastante a internet

buen, por si estos datos son relevantes, ésta es una notebook Hewlett- Packard con Windows XP Home Edition, 1.52 GHz, 480 MB de RAM y un disco rígido de 40 GB. Por favor agradecería muchísimo si alguien me podría ayudar a arreglar esta PC, GRACIAS!!

mi log es el siguiente
