You said fusebox...but I think you mean breakerbox. If I am right in that assumption; you need to check for the breaker that is open or in the off position and simply switch it back to on or closed. Some older breakers (the switches), don't open all the way when tripped. and look as if they are closed. These usually can be pushed into the closed position and spring back. To fix this simply flip it off and on again.
Now If I was wrong in the assumption that you are using a breakerbox instead of a fusebox. You may need to switch out a fuse or fuse cartridge. To check for a blown fuse take a flashlight and look into the glass window in the fuse it's self. A working fuse should look like a thin strip of shiny metal. A blown one is broken.
If that didn't help, you may have problem wiring, or a faulty outlet. Change the outlet or get your handyman to do it. If there is still a problem you need to hire an electrician.
