One morning, you wake up and turn on your computer. All of a sudden it is not working. Your screen is blank, no sound comes out of your speakers or a program does not run correctly. This course will help the user to troubleshoot and diagnose these and other similar problems. The user will be able to detect and remove fragment and bad clusters on the hard disk. The description and uses of the computer's components will be covered. Computer terminology (BIOS, CMOS, SCSI, COMM and PARALLEL ports) will be included.
