The PSU is responsible for providing power to the other components in your computer. It converts AC power from the wall outlet into DC power that the computer can use.

6. Graphics Processing Unit (GPU)

The GPU is responsible for rendering images and videos. It’s particularly important for gaming and graphic-intensive applications.

7. Cooling System

A computer’s cooling system, which includes fans, heat sinks, and thermal paste, helps dissipate heat generated by the CPU and other components to prevent overheating.

Troubleshooting Common Hardware Issues

Even with the right tools and knowledge, hardware issues can still arise. Here are some common hardware problems you may encounter and their possible solutions:

Computer not turning on

If your computer fails to power on, start by checking the power supply connections. Ensure that the power cord is securely plugged in and that the power switch on the back of the PSU is turned on. If everything is connected correctly, the issue may lie with the PSU itself, requiring a replacement.


Overheating can cause your computer to slow down, freeze, or even shut down unexpectedly. To address overheating, start by cleaning the dust and debris from your computer’s fans and heat sinks. Ensure that all fans are spinning properly and that there is adequate airflow around your computer. If the issue persists, consider replacing the thermal paste on your CPU and checking for any faulty cooling components.

Blue screen of death (BSOD)

The dreaded blue screen of death indicates a serious error within the operating system or hardware. Start by checking if recently installed hardware or software is causing the issue. If you can’t pinpoint the cause, running memory tests and updating drivers may help resolve the problem.

Slow performance

If your computer is running sluggishly, it may be due to insufficient RAM, a fragmented hard drive, or malware. Consider upgrading your RAM, defragmenting your hard drive, and running antivirus and anti-malware scans to improve performance.

Noisy fans

Loud or rattling fans are often a sign of dust buildup or failing components. Clean your fans and heat sinks to remove any dust and debris. If the noise persists, consider replacing any faulty fans.
