What is the role of the CPU in a computer?

The CPU is the brain of the computer that processes instructions and performs calculations needed to run programs.

Why is the CPU necessary for a computer?

Without a CPU, the computer cannot execute any instructions; the operating system and applications rely on the CPU.

What are common issues that can cause a CPU to fail?

Overheating, bent pins on the processor, motherboard power delivery issues, and system freezing or shutting down.

What are some fixes for a malfunctioning CPU?

Clean dust and improve cooling, reapply thermal paste, check the CPU fan, or replace the CPU if damaged.

What is the function of RAM in a computer?

RAM temporarily stores data that the CPU is currently using.

Why is RAM important for a computer's operation?

It allows the computer to run programs smoothly and multitask.

What signs can indicate RAM failure?

Blue screen errors, random crashes, computer failing to boot, or beeping sounds during startup.

How can you fix faulty RAM?

Reseat the RAM sticks, test the sticks one at a time, run memory diagnostics, or replace faulty RAM.

What does storage in a computer do?

Storage keeps permanent data, including the operating system, programs, and files.

Why is storage critical for a computer?

Without storage, the computer cannot save or load the operating system.

What are common symptoms of storage failure?

Very slow computer, files becoming corrupted, clicking noise in HDD, or system fails to boot.

What can be done to fix storage issues?

Check cables, run disk health checks, clone or back up data, or replace the drive.

What is the function of the motherboard?

The motherboard is the main circuit board that connects all components.

Why is the motherboard necessary?

It allows communication between the CPU, RAM, storage, GPU, and power supply.

What are symptoms of motherboard failure?

Computer not turning on, USB or ports not working, random shutdowns, or burn marks on capacitors.

What fixes can be applied to a faulty motherboard?

Check power connections, reset CMOS, update BIOS, or replace the motherboard if damaged.

What is the purpose of the PSU in a computer?

The PSU converts electricity from the wall into power for the computer.

Why is the PSU essential for computer components?

Every component needs power from the PSU to operate.

What are common signs that a PSU may be failing?

Computer won’t turn on, random shutdowns, burning smell, or no fan movement.

What can you do to troubleshoot a failing PSU?

Check power cable, test with another PSU, or replace the power supply.

What is the role of the GPU in a computer?

The GPU processes graphics and video output.

Why is a GPU needed?

It allows the computer to display images on the monitor.

What are symptoms of GPU failure?

No display, screen artifacts, crashes during graphics use, or driver errors.

What fixes should be attempted for GPU issues?

Update graphics drivers, reseat the GPU, check monitor cable, or replace the GPU.

What is the purpose of cooling systems in a computer?

Cooling systems remove heat from components, especially the CPU and GPU.

Why is cooling necessary for computer components?

Without cooling, components overheat and shut down to prevent damage.

What are common problems that signify cooling system failure?

Loud fans, high CPU temperatures, system overheating, or dust buildup.

What actions can be taken to fix cooling issues?

Clean dust from fans, replace faulty fans, reapply thermal paste, or improve airflow.
