CRITICAL THINKING MCQs: COMPUTER HARDWARE – MOTHERBOARD & PSU

Which of the following best explains why the motherboard is called the “mainboard”?

• It produces power for the computer

• It connects and coordinates all major hardware components

• It stores data permanently

• It cools down the processor

A computer technician connects all components properly, but the system won’t power on. Which component is most likely faulty?

• CPU

• PSU

• Motherboard

• Hard drive

If the CPU is installed incorrectly in its socket, what problem is most likely to occur?

• The PSU will overheat

• The motherboard will fail POST (Power-On Self-Test)

• The hard disk will not spin

• The monitor will display distorted images

The function of the chipset on the motherboard is to —

• store startup instructions

• regulate voltage

• control communication between the CPU and other components

• provide power to the hard drive

A student’s computer keeps restarting randomly. Which of the following components might have an unstable voltage supply?

• RAM

• CPU socket

• PSU

• Expansion slot

If a motherboard has 4 RAM slots, but only 2 are used, the remaining slots are —

• Reserved for cache memory

• Available for memory upgrade

• Used by the CPU automatically

• Non-functional

Which of the following components on the motherboard is most critical during boot-up?

• RAM slots

• BIOS/UEFI chip

• Expansion slots

• Power connectors

The ATX motherboard design is preferred in modern computers because —

• It is larger than AT

• It supports older power supplies

• It allows for better airflow and cable management

• It lacks power connectors

Which of these would best describe the relationship between the motherboard and the PSU?

• The PSU stores data from the motherboard

• The motherboard supplies power to the PSU

• The PSU provides energy the motherboard distributes

• Both function independently

When upgrading a motherboard, which component must also be compatible for the system to work?

• Hard disk

• PSU

• CPU

• Monitor
