Why are interrupt required?
Interrupts are required in order to get the attention of the CPU. A CPU typically has two interrupt lines. One is the nonmaskable interrupt line (NMI). That is used in the case of critical errors, since this interrupt cannot be ignored. The other one is the regular interrupt line. That is used by hardware devices and certain software to get the attention of the CPU. When you move a mouse, for instance, that creates both a hardware and software interrupt. So the CPU would then process the mouse driver code and move the cursor, then get back to what it was doing.

How to tell if motherboard or processor is bad?
The only true way is to replace the CPU with a working CPU and see if it works. But, if all of your other hardware devices are working then you can bet it is not your motherboard. Another words if you are getting power to your motherboard and all your devices are working, but you are having problems with your CPU then you can bet it's the CPU.
How are output devices connected to the CPU?
Output devices are connected to the CPU through the northbridge and southbridge, (collectively called the chipset) but they connect to different devices. The northbridge connects to the graphics output, while the southbridge connects to all other output devices (sound, storage, network, and others).
