if its under warranty take it back ;D

You people and taking things back! Don't you ever "fix" anything?
Stupid question yakattak: does your notebook have a floppy drive, and if so, do you have a disk in it? And if so, have you tried removing it and restarting the computer? I've had this happen a lot, and if your computer is set to boot from the floppy first, it will try to find an OS on it, which of course there is none, so it won't boot into Windows.
If that is not the problem, it is always possible that your hard drive has simply gone faulty (which would not be caused by CCleaner, as it is a hardware failure). The best way to test this out would be to take out your current HD and slip in one that you know works. Sadly, you most likely don't have any notebook HDs sitting around, but that may end up being where the problem resides.
I have changed a few notebook hard drives in the past (Dell, IBM, Canon, and HP), and it isn't difficult in the slightest. Actually, it is usually easier than swapping a desktop hard drive, because you don't have to mess with cables. But 2.5" HDs are fairly expensive. A good place to buy them is geeks.com.
Here is a link to the ones you would want.
I know that isn't what you wanted to hear, and it isn't necessarily the problem; but it is a possibility as notebook optical drives and hard drives are always the first things to go. I bought a brand new HP notebook two years ago, and the CD-RW/DVD combo drive died after 2 months! Good thing the warranty covered it!
