into electrical and mechanical problems. You will know you have a hardware
problem if the screen is dark, the computer cannot read the disk drives, or you get an
error message during the Power-On Self Test (POST).
Software errors can occur at several levels. The ROM BIOS and the operating system
can give you a large number of error messages. On top of this, each application

operating system. Once you know this, you can look in the respective manual for a
solution to the problem.
