cordial saludo. espero alguno de ustedes me pueda orientar porfavor. de antemano muchas gracias.
tengo diferentes inconvenientes:

1. la navegacion en internet se torna lenta cuando abro varias ventanas y en algunas paginas se bloquea completamente obligandome a dar reset.

2. en ocasiones al entrar a windows se queda iniciando los procesos y no termina, se bloquea.

3. en ocasiones antes de cargar el sistema operativo genera un error de no encontrar primary slave o hard disk, obligandome a dar reset o apagar.

4. cuando abro aplicaciones como power ponit se bloquea o se demora mucho en ejecutar.

tengo win xp professional service pack2.
