Hardware

Its important to understand what is inside the computer so you can understand what has failed or might fail at some point in the future. In the most basic terms, there are intigrated chips on the motherboard that hold the memory of your computer.

When you first turn your computer on there is a special chip called a ROM chip, Read Only Memory. The power supply turns on this chip first and it has a special set of instructions. The first part of the instructions are called a power on self test. What this does is check all the hardware and if somthing is wrong it reports it in the form of beeps or a error message on the screen.
