What Counts as a Computer Problem? 

When you use a PC and it doesn’t perform as you expect, you have a problem. Everything from sticky keys to memory failure can be frustrating and prevent you from using your computer to its fullest potential. Turning on and off the computer is the best first step in troubleshooting computer issues and can save you tones of time and hassle, though it’s a common joke nowadays. One of the most important first steps in troubleshooting is to ensure that all of your cables are working properly before moving on. You can try some more approachable solutions before contacting a professional before power cycling or replacing cables doesn’t work.  

The following are some of the most common computer issues, along with some suggestions for how to resolve them:  

  1. General Slowdown 

User complaints about “slow” computers are among the most common. There are numerous reasons for this. Most of the time though, it’s a reference to the amount of time it takes to do basic tasks like turning on the computer or opening Software. This can even result in input lag between what you type on the keyboard and what appears on the screen in extreme cases. As a result of its potential to affect multiple Software or areas of your computer, this problem can be extremely inconvenient.  


Nine times out of ten, a lack of—or a misallocation of—hardware resources is the primary cause of PC slowdown. This means that certain Software or processes are taking up an excessive amount of space on your hard drive, RAM, or CPU, and need to be closed.  

It takes a certain number of resources just to run the operating system, so if you have a pesky Software taking up too much of your computer’s resources, the OS may struggle. As a result, input lag and other common performance issues may arise. Using Task Manager is a simple way to find out which Software is consuming the most of your computer’s resources.  

Right-click your taskbar and select Task Manager from the context menu that appears. The “Performance” tab can be found at the top of the Task Manager window. To see how much of your computer’s resources are being used at a given time, simply click this tab. Suppose that these values are close to or at 100%. Until your computer is running smoothly again, you can close any unnecessary Software. Make sure you only open Software that you’re currently using. As a result, your computer will always be in top shape.  

  1. PC Will Not Turn On 

Nothing happens when you press the power button on your computer, and it can seem as if the world has ended. This does not necessarily mean that your computer is broken or that all of your data is gone. For a variety of reasons like 0x0 0x0, both desktops and laptops can refuse to power on. A peripheral such as an external monitor may be all that’s preventing the computer from turning on at all. You shouldn’t be alarmed if you try to turn on your PC but nothing happens. Before pressing the power or reset button a second time, wait for the computer to fully boot up. If the problem persists, try the quick fixes listed below.  


Because of their internal batteries and external power supplies, laptops are more prone to power problems than desktops. When a laptop charger or internal battery has been damaged, most modern laptops will not turn on to prevent further damage from occurring. In some cases, you can safely shut down and unplug the computer before attempting to turn it back on. It’s likely that your battery needs to be replaced if this fixes the problem. If this doesn’t help, try a different AC adapter, both with and without the battery, to see if that’s the source of the problem.  

  1. Peripherals Not Working 

There are times when your computer’s peripherals are to blame for your frustration rather than the computer itself. Because they are used so frequently, keyboards and mice are prone to malfunction. Additionally, the setup process for some other devices, such as microphones or presentation-based remotes, has the potential to cause problems later on. A malfunction in any one of these devices can result in expensive and frustrating downtime that is not ideal for any user.  


When an external device isn’t working, the first thing to check is whether or not it is connected to the computer. It’s easy for cables to snap or ports to become clogged. It is always a good idea to try different cables or connections on your computer to see if a device will start working again before looking into more serious solutions.  

It is possible to try reinstalling drivers if the cable or hardware itself is not at fault. In order to communicate with and utilize hardware, drivers are the software that your PC needs to have. There are drivers for everything, from keyboards to Wi-Fi cards. These files can become corrupt or fail to update properly, and this can cause issues when trying to use your devices.  

Device Manager can quickly reveal whether or not you’re experiencing driver issues. You can get to this area of your settings by searching or right-clicking your Start menu. There is a list of all the hardware that is connected to your computer when you open the Device Manager. There will be an exclamation point next to any hardware that has problems. When you see this message, your computer has detected the device, but it isn’t performing as it should.
