One of the Certkiller .com systems has a blank monitor and the fan on the power supply is not
working. What is the cause of this problem?
A.
The BIOS on the motherboard needs to be upgraded.
B.
The monitor is malfunctioning.
C.
The computer is unplugged.

The power supply is bad.
Explanation:
The first thing to check is the plug because nothing is going on with the system. You can only
ascertain if something is faulty with the system once it is plugged in and switched on.
Incorrect Answers:
A: You first need to switch the system on to se whether it is indeed the motherboard that needs
upgrading.
B: Since the fan on the power supply is not working, you can know for sure that the system is not
plugged in.
D: It is not a case of the power supply that is bad, there is absolutely no power since the fan does
not even work.Reference:David Groth and Dan Newland, A+ Complete Study Guide (Second
