When I turn on my MacBook, the white screen appears but it does not finish booting and show my desktop. I've tried restarting several times now.

You do realize that it's not even daytime on half the planet? Give people some time. – Daniel Beck Oct 26 '10 at 11:16

Try resetting the PRAM and NVRAM as described here. Since it's a Macbook, also reset your PMU.

Can you boot into Single User? What happens when you try?

Can you boot from the System DVD? Can you enter Hardware Test? What happens if you do/try?

@sribharanidharan: OK. If you can boot into Safe Mode, you probably have a bad driver. If you cannot boot into Safe Mode, you should reinstall Mac OS X. All your data is preserved if you don't erase the disk. – Daniel Beck Oct 26 '10 at 13:20
@Daniel-Thanks for you valuable comment – sri Oct 26 '10 at 13:25
