Learning computer hardware may not be something that interests you, but what if your computer faces a major problem someday? What if you realize there is no one to help you at that very moment? How are you going to fix it yourself? It is secondary that you may not be a tech-enthusiast or must not have taken up the best IT courses. However, it is always beneficial to have advanced knowledge and invest time in learning computer hardware. Read further to know the best ways to diagnose a computer problem.


1. Check the POST

The first rule is to conduct a POST (Power on Self Test). Check for the first or second thing that appears on the computer after you turn on the power before the operating system loads. If there are any issues with respect to the hardware, the computer would be unable to boot. And as a part of computer hardware learning, you should also know that even if it allows the computer to boot, it won’t operate at its optimum capacity.

2. Keep a track of the load time

Your boot system should not take much time to load. In case, if it does take longer than usual, this indicates that there are errors on the hard drive.

3. Watch out for graphic problems

Learning computer hardware also means that you need to check the quality of graphics. Reduced quality of graphics and lag in cursor movement indicates driver or hardware failures with graphic cards.

4. Perform an auditory test

One of the best computer hardware learning tricks lies in performing an auditory test. In this, you can judge the efficiency of your PC. Play any decent length audio file that is above 30 seconds. If you observe that the sound is slow or there is a lag, it means that the computer is running on less RAM and is incapable of running the other programs that are running. In order to apply this test, try changing the startup sound of the audio. Make sure to check the status of PIO Programmed Input/output) Mode, which affects the process of how the drive reads and writes data from a drive. If you switch to DMA, it allows faster reads, writes and can repair slow audio.

5. Check newly installed hardware

Sometimes, operating systems can conflict with new drivers. Your operating system will immediately notify you about the devices that are having a problem. On the Control Panel, go to the Systems icon, click on the Hardware tab and then click on Device Manager. Use this to control and organize the properties of hardware.

6. Install new software and diagnose it

Here, your computer hardware learning gets easier. If your computer is facing any problem, the software may require more resources than the system can provide. If an error occurs on startup, it means that the software that starts automatically on boot is causing a problem.

7. Take a look at the RAM and CPU consumption

It is one such computer hardware learning trick that the best IT courses in India would surely teach you. If your computer system is sluggish, it means that a program is consuming more resources than required. An effortless way to check this is to use the task manager and select processes. The CPU column indicates the percentage of CPU being used and memory usage determines how much RAM is being utilized.

8. Diagnose the hard drive for loud noises and scratches

If you can hear a loud noise from the CPU fan, it tells that the CPU is working at its optimum level. From the noise, you would be able to understand if the CPU has crossed its capacity.

9. Try to run a malware or virus scan

When your computer is facing trouble, one of the most common reasons that come to your mind is a virus! It is true that performance problems can be caused by malware that is infected in your computer. Running a regularly updated virus and malware scanner can keep computer problems at bay.

10. Check the issue in safe mode

The final computer hardware learning method is to examine the problem in safe mode. To enter safe mode, you can tap F8 repeatedly during the POST test. If you find that the error is persisting in safe mode, you can be assured that the operating system is to be blamed for it.


Now that you are aware of the topmost computer hardware learning solutions, you can be assured of diagnosing and fixing minor to major computer problems yourself. Use the tips mentioned above and ensure that your computer always runs smoothly.
