How and what can I do, to fix my frozen Nikon COOLPIX S3300??

Your lens is fubar. If it does same with other lens then the camera is ng.

These camera's will do that when the battery is very low sometimes.
I'm not sure that is your problem due to lack of more details, but it is a possibility.

Coolpix s3300 does not have any other viewfinder, your LCD panel is your only viewfinder. By default it cannot be turned off.
Please provide more informations so that I can help you.

I would remove the battery and re install some times this works. If you have some real physical damage it may be cheaper to buy a new one than repair if it's a point and shoot camera good luck

It seems rather apparent that you broke your camera when you dropped it. Since you publicly admitted you dropped it, Nikon isn't likely to cover it under warranty. It looks like you need a new camera...

Sorry if that wasn't the answer you wanted but if you break it, you buy it.

Sounds like the iris is stuck shut - the lens needs to be replaced.

Take the batteries out of it let it sit for about 5 minutes and then put them back in

Sorry, but there's no simple DIY fix, and any homebrew repair attempts will likely make the damage worse. Your camera's warranty won't cover the damage, so I suggest that you take it to a local camera shop (NOT the camera department in a chain store) or contact customer service via the nikon.com web site to arrange repair. Be sure to get a firm price before you commit to anything though. The fix can easily approach the price of a new camera, and repairs typically only carry a 30-day warranty.

Lens errors are fairly common. Usually it's sand or grit interfering with the lens extension mechanism. Or the camera's been dropped with the lens extended. Or the camera has been powered on, but the lens had been blocked preventing its extension. Or the battery ran down with the lens extended ...

Here's some things that you can do to try to correct it. They only seem to work for less than 50% of the lens errors, but if the camera is out of warranty, they're worth a try:

This is probably THE single most common failure among digital cameras. There's a halfway chance of fixing it yourself, described here: http://camerarepair.blogspot.com/2007/12/fixing-lens-error-on-digital-camera.html
