Gaming PC Quiz
Questions: 16 · 10 minutes
1. In performance troubleshooting, what does a bottleneck usually mean?
A component is physically blocking airflow through the case
One limiting part or workload prevents the system from achieving greater performance
Every component has reached exactly the same utilization
The storage drive has less than half of its capacity free
2. What does a monitor's 144 Hz refresh rate indicate?
It displays exactly 144 pixels per frame
It guarantees every game will run at 144 frames per second
It can refresh the displayed image up to 144 times per second
It responds to input in exactly 144 milliseconds
3. Before buying a longer graphics card for an existing PC, which physical specification is most important to verify?
The number of icons on the case's front panel
The capacity of the current storage drive
The monitor's diagonal screen size
The case's GPU clearance, including obstructions from fans or radiators
4. With the same game and graphics settings, moving from 1920×1080 to 2560×1440 most directly increases which workload?
The GPU's pixel-rendering workload
The amount of electrical power stored by the PSU
The number of physical CPU cores in use
The motherboard's available expansion slots
5. A game installed on a hard disk has long loading screens, but its frame rate is steady once a level loads. What would an SSD most directly improve?
The monitor's maximum refresh rate
The CPU's number of processing cores
The GPU's amount of VRAM
Loading and file-access times
6. What is the primary job of a gaming PC's power supply unit?
To reduce the temperature of the CPU and GPU
To convert incoming electrical power and deliver suitable power to components
To store electricity for use during a power outage
To increase the clock speed of every installed component
7. A 144 Hz monitor is connected, but Windows and games remain capped at 60 Hz. What is the best first step?
Increase the CPU's core voltage
Move the game from an SSD to a hard disk
Check the operating system's display refresh-rate setting and connection support
Add more case fans to prevent display throttling
8. A PC begins stuttering when a game, browser, and voice-chat app are open. RAM usage is nearly full, and storage activity spikes. What is the most relevant upgrade?
More system RAM
A monitor with a higher refresh rate
A case with additional RGB lighting
A motherboard with more audio ports
9. Which practice best reduces electrostatic-discharge risk while installing PC components?
Work on carpet so dropped parts have a soft landing
Leave the PC powered on so excess charge can flow through it
Hold components by their exposed contacts to keep them steady
Power down and unplug the PC, handle parts by their edges, and use proper grounding such as an anti-static wrist strap
10. When choosing a PSU for a new graphics card, which approach is most appropriate?
Check total system demand, required connectors, PSU quality, and reasonable headroom
Choose based only on whether the PSU physically fits the case
Match the PSU wattage exactly to the GPU's listed power draw
Buy the highest-wattage unit available regardless of the build
11. What is VRAM primarily used for during gaming?
Supplying reserve electrical power during demanding scenes
Storing the operating system permanently when the PC is off
Holding graphics data such as textures, frame buffers, and rendering assets for the GPU
Handling network traffic between the game and its server
12. You have two matching RAM modules and a motherboard with four memory slots. How should you usually install them for dual-channel operation?
Place both modules in any two adjacent slots
Stack both modules in the slot nearest the CPU
Use the paired slots specified in the motherboard manual
Use the two slots farthest from the CPU on every motherboard
13. Which component performs most of the real-time graphics rendering in a typical gaming PC?
Power supply unit (PSU)
Graphics processing unit (GPU)
System memory (RAM)
Solid-state drive (SSD)
14. What is the main difference between system RAM and an SSD?
RAM provides temporary working space, while an SSD retains files without power
RAM permanently stores files, while an SSD only holds active programs
RAM processes graphics, while an SSD processes game logic
RAM powers components, while an SSD regulates their voltage
15. CPU temperatures become unusually high immediately after reinstalling the cooler. What should you check first?
Whether the GPU has enough video outputs
Whether the game is installed on an NVMe drive
Whether the monitor supports adaptive sync
Cooler mounting pressure, fan connection, and thermal-paste contact
16. A game runs slowly at 1080p. Monitoring shows the GPU staying near 99% usage while the CPU remains around 50%. Which change is most likely to increase frame rate?
Replace the SSD with a larger model
Reduce graphics settings or upgrade the GPU
Add a second monitor with the same resolution
Install a higher-wattage PSU without changing other parts
