Which of the following precautions should be taken to minimize the risk of damage to add-on cards
and motherboard? Each correct answer represents a complete solution. Choose three.

A.
Keep water and liquids away from them.

B.
Wear an antistatic wrist strap when handling them.

C.
Always clean them with a water spray gun.

D.
Keep them in antistatic bags.

Explanation:

In order to minimize the risk of damage to add-on cards and motherboard, users should take the
following precautions:
Keep them in antistatic bags whenever they are removed from the computer. Antistatic bags protect
them from static charges. Keep water and liquids away from electronic circuits, as they might cause
short circuits. Wear antistatic wrist strap while handling or repairing a computer. The antistatic wrist
strap prevents static electricity from building up.
Users should protect their computers and sensitive components such as RAM from short circuits and
static charges, as they can cause critical damage to electronic components.

Answer option C is incorrect. Add-on cards and the motherboard should not be cleaned with a water
spray gun. It can destroy them. In order to clean them, compressed air and isopropyl alcohol can be
used.
