I remember when I first got my dell inspiron 530 the loading time would be really fast, after few months of using it, when you boot and after passing the Vista loading screens theres a complete black screen. The black screen now last 5 minutes before vista finally loads up, If anyone know why its doing this please post a reply. Thank you.
