Examination of the computer are classified into several categories.
Categories visual inspection
Visual inspection is an examination of the early stages of the examination of some of the problems that can be captured easily by the eye or the five senses. Visual inspection for example:
• Check the cable connections, such as power cable or data cable. Is there a cable loose or not connected.
• Examination of "jumpers" like jumper motherboard, hard disk or CD ROM. Whether the configuration is correct

• Examination of "jumpers" like jumper motherboard, hard disk or CD ROM. Whether the configuration is correct
• Examination of the installation is there a loose RAM Socket
• Checking the installation of cards like graphics cards, audio and so on
• Examination of PCB-if there are bent, broken lines, or "burn-out", is there a chip burned and so on.
Sound Categories Examination
Sound examination is an examination of the components by listening to the sound of their own that can provide a sense of the condition of the computer.
• mechanical noise may be heard from a round disk, fan rotation and others. Is it normal or unusual sound
• Detection of beeps that appear during POST.

Categories Examination Conditions
These checks require more specialized such as touching the chip to sense the temperature. CPU have overheated, it will cause problems. If the CPU has a large chip such as EPROM, should have warm temperatures have small chips while not direct heat. Ceramic Chip hotter than those made of plastic. If it's too cool, this might indicate that chip off or there is no current through.
Inspection category cues
This is a last resort if all measures are unable to detect and solve problems. This examination is more complicated requiring special equipment, documents, images, and system knowledge on systems and electronics.
