20+ practice questions focused on Motherboard — one of the most tested topics on the CompTIA A+ Core 1 220-1201 exam. Each question includes a detailed explanation so you learn why the right answer is correct.
Start Motherboard PracticeA technician is troubleshooting a high-end workstation that randomly freezes during heavy 3D rendering. The motherboard has an X299 chipset with an LGA 2066 socket. The CPU temperature is normal, and the RAM passes MemTest86. Which motherboard component is most likely causing the instability?
Explanation: Random freezes under heavy load, with normal CPU temps and good RAM, often point to the chipset overheating. The chipset (e.g., X299) manages high-speed data transfer between the CPU, GPU, and storage; if its heatsink is clogged or the fan fails, it can overheat and cause system instability. This is a common issue in workstations with heavy I/O demands.
A user complains that their computer sometimes fails to boot and emits a series of long beeps. After several attempts, it boots normally. Which motherboard component is most likely failing?
Explanation: A series of long beeps during POST typically indicates a memory (RAM) issue. Intermittent boot failures with beep codes point to a failing RAM module, a dirty contact, or a loose connection. The beep code is a diagnostic tool from the motherboard's BIOS.
During a routine hardware upgrade, you install a new PCIe x16 graphics card into a desktop motherboard. The system powers on, but the display remains blank. The graphics card's fans are spinning. What should you check first on the motherboard?
Explanation: When a dedicated graphics card is installed, the motherboard often disables the integrated graphics port. If the monitor is still connected to the motherboard's video output, it will remain blank. The first step is to ensure the monitor cable is connected to the new graphics card's ports.
A customer reports that their computer will not power on. The power supply fan does not spin, and the motherboard's power LED is off. You have verified the power cord and outlet are working. Which motherboard component is most likely causing this issue?
Explanation: The motherboard's power LED not lighting up and the PSU fan not spinning indicate a lack of standby power, which is typically supplied through the CMOS battery or the PSU itself. However, a failed CMOS battery can prevent the system from retaining BIOS settings, but it does not usually stop the PSU from providing standby power. The most common cause in this scenario is a failed power supply, but since the question focuses on the motherboard, a shorted motherboard or a failed power-on circuit is the likely culprit. The correct answer is a failed motherboard power-on circuit, as it can prevent the PSU from turning on even if the PSU is functional.
A client wants to upgrade their desktop PC with a new, faster processor. They have purchased a CPU that is listed as compatible with the motherboard's socket type. After installation, the system powers on but displays a blank screen. What is the most likely issue?
Explanation: Even if the CPU fits the socket, the motherboard's BIOS/UEFI may require an update to support a newer CPU model. This is a common scenario where the hardware is physically compatible but the firmware is outdated. The system powers on but fails to post because the BIOS does not recognize the CPU.
