When i turned my laptop on last night it flashed up the dell logo like normal, this is usually followed by a loading bar which zips along in seconds and is followed by the windows logo and then the login screen, only it wasn't.

It just stuck on that little loading bar for ages and ages not doing anything.

When I restarted it it asked if i wanted to run the start-up fault check thing and when i pressed yes it just reloaded the question screen again and if i pressed yes again it reloaded the same screen again and so on.

If I pressed to start windows normally the original fault would happen again.

What gives.
