the vaio laptop gets stuck on start up page

[tooba]

I was using my laptop as usual, when it suddenly hanged. As I was in a hurry I forced shut it. When I restarted it, it wouldn't go past the start up screen. Tried the windows repair mode, but it would remain stuck at the blue welcome page. What could be the issue?

If Win7, have you tried going into safe mode?
