Do you know what to do when the screen turns white? What should you do when you can't close the application, or you can't hear the sound from the speakers? Don't panic if your computer is having problems. Computer problems can interfere with your daily work.

There are many basic troubleshooting techniques to solve such problems. Most problems are software problems, and some are hardware issues. And some may be due to one or the other. This article provides some simple things to try out when troubleshooting and solutions to common problems you may encounter. Although each computer is different, there are some common problems and solutions for computers, and it is worth learning to use your PC better. Here are five common problems, their causes, and simple solutions you can do yourself.


Online Course: Computer Repair and Troubleshooting 101

What is troubleshooting?

"Troubleshooting" usually refers to resolving a problem that causes a machine (especially a computer) to stop working, behave poorly, or behave abnormally. But specifically, it refers to a system that takes a few steps to solve the problem.

The basic representation of the troubleshooting process is:

Identify specific problems: Determine what your computer is not doing, what you want it to do, and what you don't want it to do.

Consider a connection to a similar scenario: think about a problem similar to the current one you have on your computer before. Recall how these problems were solved and consider what was the same and different in the case.

Guess and address common causes: Think of some simple things that can't make your computer work as you want it to. Check and fix these issues to see if the problem is resolved and if the problem does not recur immediately afterwards. If so, you are done. Otherwise, go to step 4.

Test related components: If none of the common solutions works, systematically check each part of your computer's system (any needed) that may be causing the problem.

Run a solution for the problem's components: If you think you've narrowed down the part of your computer causing the problem, consider and test ways to fix it.

Some common computer troubleshooting

My computer is running slowly


If running a Windows-based computer, you should know that all the software is automatically installed on your computer's C: drive. In addition, all official documents are stored in the Documents folder in C: Drive. So, if the C: drive is full, it will certainly affect the speed of your computer. So, you need to open the My Computer folder and check the size of the C: drive.

You will see a red bar under the C: drive: Specify that the drive is almost full. So you need to uninstall some applications or move the documents to another drive.

The computer may be slow for videos or files that are downloading websites that take forever or a long time to load.


You should know that much software starts when you start your computer's desktop. You can search the Microsoft System Configuration or any tool to see which applications are open when you start your computer.

Computer hangs

It is one of the most familiar issues faced by computer users. This issue can happen for a sort of reasons.


Missing DLL files

Another common system problem for Windows-based operating systems is a DLL error. It means that the DLL file is missing or corrupted. Files ending in. DLL " are dynamic link library files. A DLL contains many programs' code, instructions, and instructions. It exists to tell how the OS treats a particular application. In addition, it can open multiple programs at once, improving memory conversion.

These are the required system files; bad things happen if they are missing or damaged. It is unfortunate, but it is common because of the large number.


Low disk space

Many users don't understand the need for enough disk space and have installed large programs leaving a few MB in size on the C drive. Always make sure that the Windows installation disk has enough free space. It allows the program to use the necessary space at runtime. For example, game apps require a lot of space and memory at run time. If you run out of space, other applications and Windows OS may crash.

Relying on your hard disk size, ensure that your PC has at least 1 GB of free space and relative RAM size. If running out of space, consider using a cloud platform such as OneDrive. Also, delete files and programs you don't use to make room.

My computer screen freezes

If your computer freezes and doesn't respond to your mouse or keyboard, the first thing to do is wait. It may bring several minutes for the computer to process. Then close the program that does not respond. If that doesn't work, press and hold the power button, turn off your computer, and restart it in safe mode (remember to save your work first, if possible).

If the lock is still not released after this, it may be bad hardware or a device driver. In such a case, replace the defective product immediately to avoid further damage.

Another possibility is a virus that is putting a strain on the system. Run a virus scan, clean the virus, restore or reinstall the corrupted files and software, and deploy the latest security software.

Applications run slowly

There are several explanations why an application might operate slowly or hang. But the most common is about processing power and memory.

The computer's memory (random access memory) temporarily stores data while a program is running. For Windows users, 2GB or more is recommended, but it is ideal if there is more. RAM does not necessarily speed up your computer, but it can make your applications and programs run better. Yes, it's generally related to performance and speed.

Software runs slowly

There are many reasons why computer software may run slowly. But the most common reasons are processing power and memory.

You should know that RAM (random access memory) temporarily stores data and programs. Low RAM can slow down the software. Windows users must use 4GB or more of RAM. RAM does not speed up your computer, but it can make your software work better. 

Keyboard issues

If background noise is on your keyboard or repeated words are not typed correctly, there may be nothing wrong. To cause this problem, enable toggle and filter keys in Windows settings. To turn them off, do the following:

Accessibility can be found in the Control Panel

Change how the keyboard works. Click the button to change how the keyboard works.

Clear the check boxes next to Toggle Keys and Filter Keys to address this problem.


Power-Related Troubleshooting

Suppose the screen is empty after you press the power button. In that case, the cause may be a loosened monitor cable, incorrect plug removal, faulty electrical outlet, dropped breaker, or power stripe outage. Check for possible causes.


My PC continues to disconnect from my WiFi network

If your PC is disconnected many times while WiFi is working properly, your network card may not be getting enough power. The Windows network card includes power saver options to reduce power consumption. This feature must be turned off.

POST Failure

Sometimes POST does not complete, a blank screen appears, and the beep does not sound. In this case, replacing the power cables, peripherals, and RAM-memory modules may resolve the problem. You may also need to improve connectivity.

Power supplies that are on the verge of failure may also cause the POST check to stop. If possible, check the power and then proceed to check the RAM.

No sound

Solution 1: Check the volume level. Click the audio button at the screen's top right or bottom right to ensure the sound is bent and the volume is twisted.

Solution 2: Check the audio player controls. Many audio and video performers have particular audio controls. Make sure the player turns the sound on and the volume is up.

Solution 3: Check the cable. Please make certain that the external speakers are linked to the proper audio or USB port and that they are turned on. The audio output ports are usually green if your computer has colour-coded ports.

Solution 4: Plug the headphones into your computer and check if you can hear the sound from the headphones.


Computer overheating

My computer is overheating. You may experience symptoms of an irregular restart or a periodic shutdown.

Barrier Of Ventilation Hole

If a vent is blocked, the computer cannot be ventilated, cold air is not taken in, and hot air is not expelled. Make sure that the fan diffuser is not blocked by anything. Leave at least 6 inches around the vent.

A dusty fan or case

Dust in the fan or case can also interfere with ventilation. Open the case and check for dust; the fans are typically attached to the front and back of the case. Common locations include high-performance components such as power supplies, CPU heatsinks, and dedicated video cards.

Clean by removing dust with compressed air or manually removing it. Using compressed air, stop the blade to avoid damaging the fan bearings.

Fan Corruption

A fan failure can cause your computer to overheat. If your computer is powered on and the fan is not spinning, follow this guide to replace the fan.

Dust on the Heat Sink

When dust accumulates in the heat sink, cold air does not flow. Components with heatsinks are heat-generating and can cause the most problems with overheating the computer.

Slow or unresponsive internet browsing

If your Internet is slow or unresponsive, you may have a combination of software and hardware problems. However, if you have already verified that your WiFi or LAN network connection is active and strong, the delay can be due to IP address registration conflicts. It can be fixed by restarting the modem or router. If that doesn't fix the problem, there might be a problem with your browser.

If a large amount of browsing history and cache remains, browser performance may deteriorate. There may also be a bug in the browser extension that is causing poor performance. To make your browser work more efficiently, check your internet search history and cache regularly. If that doesn't work, you can try reinstalling your browser or use another browser to see if the same problem occurs.

Regular PC maintenance

One way to prevent trouble is to stick to maintenance. It's also a matter of not doing maintenance while using the PC, but I think the relationship between the PC and humans will be better by following the keywords below.


Final Words

One of the major methods to bypass having to know how to troubleshoot common PC hardware problems is to concentrate on preventative maintenance. Most people (and businesses) tend to ignore or patch their burgeoning problems. While these can be short-term fixes for small things, the value of following a long-term strategy to ensure the technology continues to operate is not underestimated. Time, frustration, money, and security are always more than the value of procrastination.
