Depends on the make and model. It is generally a good idea to turn off anything that you are not using because it extends service life. If your modem is a wireless router, than if you turn it off, no one in the neighborhood can use it(provided they had your security info ) but neither can anyone else in your house. Also, some modems sap power and stay warm when the computer is on.
If you want to leave it on, nothing will break. However if you want your modem to last as long as possible, save power, and prevent it from being used by someone other than yourself than you should turn it off.
you should try and delete files of the computer to lower the shut down rate

Your motherboard (commonly called your processor) is the brain of your computer, it tells your computer what to do from boot up to shut down, it tells your hard drive to boot up Windows when you boot up your computer, and to shut down Windows when you turn it off. It controls every piece of hardware in your computer.
