Top 10 Most Common Computer Issues/Problems/Errors And How To Fix Them in the Year 2021-2022


Several general computer issues may be traced back either with software or hardware malfunctions. Many of these suggestions are simple to implement.


Most people have encountered many basic computer problems at some point while using a computer. In other words, don’t freak out. Here are the top 10 most frequent computer issues and how to solve them yourself.


1.      When the Computer is not turning on


Plenty of us confronts this issue regularly. This issue may be compared to the human body to comprehend it better.


Infection is a severe symptom of illness. The body uses this as a defensive measure against illness. Similarly, if your computer has a problem, it won’t even start unless you solve it.


When a computer won’t start, there is a myriad of possibilities. From a faulty power source to virus infection, problems might arise at any time. However, if you follow the instructions following, the system should always start properly.


Strategies/remedies to Solve Basic Computer related problems/issues:


a.      Determine whether there’s a problem with the power supply


When using a laptop, a lack of power might be caused by a dead battery. Hook/Plug it in and wait for it to charge for at least a few hours. If something doesn’t work, you may want to try a new adapter/charger to see if that fixes the problem. When plugging in the charger, see if the power indicator is flashing.


If the desktop computer won’t start, simply plug it into a separate socket to see if that’s the problem. If it doesn’t work, you may have a problem with your computer’s power supply.


b.     Ensure that the display or monitor is working properly.


A few things might be wrong when you can see that the computer system has power, but nothing still occurs, such as the fans starting up or the power indicators/lights going on.


The exterior monitor might be the problem if you’ve a desktop Computer attached to it. First, make that the display is plugged in and linked to your computer. Moreover, try disabling and re-establishing the connection. Connect an alternative monitor if feasible if that doesn’t work. There is a good chance that the computer display/monitor is at blame, but you may also rule it out.


The problem might be that your PC is in sleep mode and is experiencing difficulties waking up if you use a notebook/laptop or have ruled out the extra screen/monitor/display. To see whether that’s the case, shut it down and restart it from scratch. To accomplish this, press and hold the power button for five seconds before restarting your computer.


c. Remove extraneous hardware from the equation


When none of those mentioned above fixes the problem, it may be time to check the accessories. This might be due to a malfunction in the power circuit or a malfunction in the external device.


If it doesn’t work, restart the computer and see if that fixes the problem. Then, move on to the next final step if it doesn’t work.


d.     Reinstalling the system is another option


When none of the other options work, reinstalling Windows is the very last thing you’d would like to do. But, so far, it’s clear that this is a software problem rather than a physical one.


So If you can’t access your data because you can’t just switch on your system, there seem to be, however, ways to backup up your information from the hard disk. In addition, if your computer is damaged or corrupted, a fresh reinstall will assist restore it to its original state.


2.     Internet Slowness


Sluggish internet access is one of the most aggravating things that may happen. Netflix, YouTube, and Facebook are out of the question for you, I realize.


In most cases, though, resolving this issue is a simple matter. Problems with your internet service provider (ISP) as well as your own internet service provider (ISP) are two separate difficulties (associated with your ISP)


Strategies/remedies to solve this Slow Internet Problem:


a.     Firstly, reboot the modem/router.


And that is how you would fix any device using this approach. For example, a power surge or excessive internet usage might cause the modem to become overloaded.


It’s as simple as turning off the modem device for a few minutes and turning it back on. Then, most of the time, you’ll be OK.


b.     Make sure your wi-fi signal is strong enough.


Your router and internet may be good, but your wireless signal isn’t. An increase in latency might lead to a decrease in performance. This might need a few tweaks and adjustments to your modem/router.


Look at this link to learn how to repair your wi-fi connection with some helpful advice.


Disable or remove any unwanted background programs.


In certain cases, idle background operations, such as software upgrades or other apps that use the internet, may slow down your internet connection.


Accessing your task manager will provide the list of these programs, and you may start killing them off. This may be done by disabling upgrades in the settings.


c. Notify your Internet service provider (ISP)


Your internet service provider may be at blame since none of the preceding fixes the problem.


The issue might be due to a networking update, adverse weather, or the need to repair damaged cables. Certainly, they’ll take a look at your internet connection and tell you what has to be done.


3.     Slowing down of the Computer


When it takes like five minutes to launch a single app, I know what you’re going through. Fortunately, this is an issue that many individuals encounter on a regular basis.


The length of time you’ve been using the computer is frequently the source of the problem. Irrespective of its specs, a system/PC that is more than two years old or more will suffer this.


Solutions/remedies to slow PC problem:


a.     First, locate a resource-intensive program.


If you have a lot of applications running, there are certain to be a few that consume a huge amount of resources, such as a ram.


Using the Task Manager is a great place to find out. If you right-click your taskbar and pick “Task Manager,” or if you hit Ctrl+Shift+Escape, you’ll be able to launch the task manager. When using Windows 8 and later versions of Windows.


The CPU, Memory, and Disk headers may be used to rank the lists by even the most resource-intensive apps. Otherwise, you may pick the program and click “End Task” here to make it to shut down if it’s taking up too much computer resources. 


b.     Start-up programs should be disabled


One of the most common causes of PC slowdown is the use of starting apps that are set to run automatically.


There is now a startup manager in the Task Manager for managing your startup applications on Windows 8/8.1/10/11.


Choose “Task Manager” by right-clicking the taskbar or pressing Ctrl+Shift+Escape to open it. Stop/disable any startup apps you don’t need by switching to the Startup tab.


It’s a good idea to keep track of which programs are slowing down your computer’s startup process.


c.      For malware and adware, run a system scan.


Everyday computer use might result in the unintentional acquisition of malware and adware.


Whenever we visit the web or download anything, we’re often inadvertently downloading malware.


As a result of the need to transport data over the internet in case of confidential info theft, such apps may slow down your computer.


Utilize your computer’s built-in antivirus software to check for and delete the infected files. 


4.     Problems with Windows updates


A wide variety of factors may cause Microsoft Windows to upgrade failures. For example, windows infringement, deleted core libraries, licensing concerns, etc., are all possible reasons.


Nevertheless, the situation is not so terrible. However, if you want the most up-to-date software and security, you’ll have to repair the problem.


Strategies/remedies to solve problems related to Windows upgrades:


It’s a simple matter to solve. Checking the errors and troubleshooting mechanisms built into Windows can resolve this.


The original Microsoft Windows upgrade error resolving instructions may be found below if you still can’t solve it.


5.     A Hard Drive That Makes a Lot of Noise


Whenever a hard disk is being used or shut off, it is very common to hear a muffled clicking noise.


As just an alternative, if anyone hears sounds something you’ve never experienced before, such as crushing or screeching sounds, your hard drive might be deteriorating, and you’ll need to replace it.


Strategies to solve the hard drive weird sound issues:


a.     First, check to see if there is any noise coming from the hard disk drive


Hard disk drive noise is the most common sound people encounter from computer devices. Because when the sound abruptly grows louder, people presume that it’s coming from the hard disk drive.


The easiest way to verify this is to disconnect the hard drive’s power transmission connectors and restart the computer. The hard disk is not the problem if you can yet hear the noise.


b.     Secondly, run diagnostic software.


Freeware hardware testing software is available on several computers or may be accessed online from the internet to download if you’re sure the sound originates from the hard disk drive.


c.      The hard disk should be replaced.


A problem with the drive’s hardware will be evident if the diagnostics application does not work as expected. The only option is just to replace it if such is the case.


You should make a copy of the data/files before replacing the hard disk drive.


6.     The Computers fan isn’t running.


This is yet another typical issue with computer equipment. In contrast, individuals tend to worry if the fan fails to function.


The CPU fan will cease operating whenever the CPU temperature drops or you are not using any power-hungry programs.


Almost all of the time, it’s the motherboards that’s at blame, not really the fan.


Strategies/remedies to solve the faulty Fan problem:


a.     The first step is to identify the source of the problem.


As previously stated, the motherboard is the most common cause of the fan to cease working. However, due to a lack of proper board installation, or an issue with board cables, this may occur.


For this, all you need to do is plug the fan over and see whether it’s really running. Yes, if that is the case, therefore, the fan is the issue.


b.     Take a look at the fan base


The following are the most prevalent fan-related problems:


Fan on a computer’s central processing unit (CPU) continues to protect from dust particles


There’s a problem with the CPU fan bearings.


The CPU fan has damaged


One may use a cloth to clean anything in the first instance. However, you’ll want to focus on the 2nd and 3rd examples, which are more significant.


7.     There is a problem with my printer.


For starters, examine and see if there are any errors or indicator lights on your printer, and then move on to more complex issues.


Try and ensure there are really papers in the paper tray(s), verify the ink or toner cartridges aren’t emptied, the Power cord is hooked in, or the printer machine is linked to Wi-Fi.


The answer presented here will assist you in resolving the majority of your problems.


Strategies/remedies to solve printer issues:


First of all, turn on your printer.


Several miracles may be accomplished just by stopping all current printing and restarting the printer.


There are a few possible explanations for all of this, including an overcrowded printer or fresh inks cartridges. So restarting the printer is all that is needed to bring everything back to normal.


If there are any problems with the PC/laptop, you should look into it.


Each printer is equipped with software drivers that enable it to be used with a PC. In addition, a diagnostic/troubleshoot mode may also be shown if there are any concerns relating to it.


During this time, most of the problems can be solved. The printer drivers should be up-to-date and working properly.


8.     The Blue Screen of Death Usually abbreviated as BSOD


A Blue Screen of Death (BSoD), also known as “blue screen,” “stop error,” or simply “system crash,” occurs when the system is unable to process and rectify a serious problem.



Likewise, It’s a full-screen, blue error message that appears after a major system failure. For the uninitiated, “stop message” or “stop error” is really simply a popularized word for what’s really known as an error message.


There are several reasons why you can get a blue screen of death, but the most aggravating is that it’s simply a screen with a blue backdrop and a sad character face with too few details to work out what’s going on.


Strategies/remedies to solve Blue Screen of Death issues:


Test to see whether there is adequate room for new features to be added.


a.     Data corruption, file system breakdowns, and system storage issues are the most common causes of a BSOD.


A damaged or corrupted file may occur if your system storage is full when in an upgrade, leading part of the files to be absent.


b.     The second step is to run a virus scan on your PC.


When an MBR or boot sector is infected, viruses may trigger a Blue Screen of Death, particularly when the MBR or boot sector has been corrupted.


c.      Make sure your computer’s hardware drivers are up to current.


The majority of Blue Screens of Death are caused by hardware or driver issues, which may be fixed by updating the drivers.


d.     Reset the BIOS default configuration to their default parameters/values, if needed.


BSODs may be caused by a variety of problems, along with an improperly calibrated or corrupted BIOS.


e.      The fifth step is to conduct diagnostic checks on every hardware you have access to


Every time you see a Blue Screen of Death, it’s almost always because of a malfunctioning computer component.


9.     Inability to Use Computer or it freezes and crashes


Occasionally, a PC that is too old or sluggish can seize up. This is because there are simply not enough resources to go around.


Windows should begin to slow down until you notice this issue on a routine basis. That may be remedied by reading the preceding paragraph.


10.  When a problem occurs, the system will automatically reboot/restart itself.


Extremely frustratingly, this will be the last topic we’ll address in our list of most typical computer issues here.


Such an issue arises for a variety of causes. For example, it might be caused by damaged drivers, a malfunctioning computer, or even a malware attack.


It might be tough to figure out what is causing your PC to restart itself over and over again. But, even after a Windows update, it’s most likely to occur.


Strategies/remedies to solve the System automatic crashes:


a.     Removing corrupted registry entries


Unless you are certain that you might not make a single error, you should not proceed with all this.


Windows Registry is a critical dataset. Simply losing even the most little punctuation mark may do serious harm to your computer system! As just a result, I highly recommend using Auslogics Registry Cleaner, such as a one-click approach.


This free registry cleaner scans the system for unused or faulty files.
