No puedo abrir carpetas. Se me congela el ordenador

[Ceci05]

Hola



Desde hace tres días me ha estado pasando que cada que intento abrir una carpeta ya sea con doble clic o con el botón secundario, la pc se congela y tengo que reiniciar. Puedo hacer todo lo demás, abrir programas, juegos, ver videos, navegar, pero en cuanto quiero abrir alguna carpeta aparece el reloj y de ahí no pasa.



Uso Windows XP, el antivirus (tengo el AVG) y el AVG Antispyware no me reportan nada. ¿A que puede deberse?



Gracias de antemano y saludos.
