What type of Nintendo? If you have a Nintendo Gamecube, first of all you need to plug it in and connect it to the input ports of your TV or Monitor, or any device connected to your TV (such as your VCR). Then, you need to figure out how to access the input ports on the device you used, which will be different for every device. For example, my home TV has 3 sets of input ports, and my GameCube is hooked up to the second set of input ports. There is a button on the front of my TV that says TV/Input. Pushing this button once accesses the first set of input ports, pushing it again accesses the second, again the third, and again back to normal cable TV.
After you've hooked everything up, turned on your TV/Monitor/Vcr etc. and accessed the input, push the circular power button on the top of the Nintendo GameCube, and it should start. You should see the GameCube logo appear on your TV/Monitor.
