My pc uses about 15 minutes to start up. I use XP home edition and when i power on the pc it just show me a Packard Bell screen for about 15 min. before something happens. Help me please !

If the computer continues to be slow even when it's all loaded, e.g. getting on the internet and stuff you could have downloaded a wrong driver like I did This means you have to find the files and get rid of them, a small pin in a very large proverbial haystack. The way I overcame this is a full system re-boot

Hope that helps
