At any moment, you may face a computer glitch meaning your system is malfunctioning. Since it can be quite difficult to detect where the problem lies, many users are asking, why is my computer glitching? If you are in the same predicament, just keep reading. In this article, you will learn why glitches occur, how to resolve major computer issues caused by them, and how to improve computer performance.

A Computer Glitch: Meaning

A computer glitch is one of the numerous computer issues that prevent PCs from working normally. In the most common sense, it is an error or problem that affects a computer and causes it to behave in an unexpected or strange way.

Here are some examples of computer issues that can be described as glitches:

  • A frozen screen
  • Distorted visuals
  • Program crashes
  • Strange system messages 
  • Input delay
  • Distorted audio
  • Unexpected noises

In most cases, glitches are temporary and can be easily fixed. A simple act of restarting your computer or updating certain software may be enough. However, sometimes, glitches indicate that you need to resolve major computer issues, and doing it may require the help of dedicated software.

Common Reasons for Computer Glitches

At this point, you may be asking, why is my computer glitching? There are several factors that are common culprits for computer issues like glitches:


At times, the components of your PC, like the CPU or graphics card, can get too hot and won’t cool down. If you don’t stop it, your PC may overheat and trigger a computer glitch, meaning it’s too hot for it to work seamlessly. This can happen for a few reasons:

  • Highly intensive tasks: If demanding or graphics-intensive apps put too much strain on your system, computer issues like glitches may occur. 
  • Dirt and dust: Dust and dirt accumulation blocks the airflow and prevents cooling.
  • Blocked vents: If your computer’s vents are blocked, the heat can’t escape and overheating happens.

Your system’s components cannot work properly when they are so hot. In some cases, they can even get damaged beyond repair. If you want to avoid that, make sure you know how to prevent overheating.

Malware and Virus Infections

Still asking, why is my computer glitching? Chances are high that your PC is infected with malware. Slow performance, unexpected behavior and strange messages are common indicators of malware infection. Whenever a malware entity enters your system, it starts to cause harm, which leads to various glitches and other computer issues appearing on your PC.

To stay safe, you need to know how to remove viruses and other malware from Windows. For instance, you can do that with the built-in Windows Security tool: 

  1. Open the Settings app by pressing “Win + I” on your keyboard.
  2. Go to the Update & Security section, select “Windows Security” and click “Open Windows Security.”
  3. Open Virus & threat protection and click “Scan options.”
  4. Check the type of scan you wish to run and click “Scan now.”
  5. Windows Security will check your PC for threats and let you remove or quarantine them.

Hardware Issues

Computer issues that trigger glitches are often related to hardware. Which is why users that have faulty hardware components often ask, why is my computer glitching, and why is my computer so slow?

There are several hardware issues that often lead to computer glitches and general PC slowdowns:

  • RAM Problems

From multiple beeps to random freezes to Blue Screens of Death, bad RAM (Random Access Memory) can cause persistent glitches that would try the patience of a saint. Your RAM can become faulty due to various reasons, such as overheating, physical damage, and wear and tear.

To fix faulty RAM, try reseating its modules. If that doesn’t help, test them separately to identify the culprit. Another option is to run the Windows Memory Diagnostic tool to troubleshoot memory-related computer issues:

  1. Press the “Win + S” keyboard combo and type Windows Memory Diagnostic into Search.
  2. Select the corresponding result.
  3. Decide when you want to check for problems and let the tool perform diagnostics.

  • Hard Drive Problems

A computer glitch meaning your hard drive is faulty will most likely appear as a crash or performance slowdown.

To begin with, check the cables connecting your hard drive to the motherboard. You can also try using a different cable or port. All to no avail? Then it’s time to run a command called CHKDSK. It will scan your drive for file system errors, bad sectors and other computer issues:

  1. Open File Explorer, go to “This Computer” and right-click the drive you want to check.
  2. Select “Properties” and proceed to the “Tools” tab.
  3. Click on “Check” under Error checking.
  4. Click Scan drive and wait until the tool is done checking your drive for problems.
  5. Let it fix them if any are detected. You may need to restart your PC for the tool to perform repair procedures.

  • Power Supply Unit (PSU) Problems

“Why is my computer glitching?” is a popular question among users with power supply issues. If your PSU is faulty, you are likely to face system instability, random restarts, and other computer issues.

Here are some tips on how to fix a problematic PSU:

  • Check your power cables and make sure they are properly connected to the PSU.
  • Test your power outlet and cables with another device.
  • Connect to another PSU to check if yours is faulty.
  • Replace your PSU if you are determined it is faulty.

Software Issues

  • Outdated Software

In Windows 10, software is often behind computer issues. For instance, outdated software, including drivers, can trigger costly glitches.

If you want to learn how to keep your driver software up to date and avoid glitches like freezes, crashes, lag, and slowdowns, we recommend you to read our article on how to update device drivers on a Windows 10 PC.

Of course, running the latest driver versions is not enough if you want to use a glitch-free PC. All the apps you have installed should receive regular updates. The sooner you learn how to keep your software up to date, the better.

  • Software Bugs

Unfortunately, apps do not always work as intended. They often have flaws called bugs, which are usually mistakes in their code. All sorts of computer issues occur as a result, including glitches like freezes, crashes and other examples of strange software behavior.

  • Software Conflicts

Apart from outdated programs and occasional bugs, software conflicts are another reason why you may experience glitches and other computer issues on your PC. Software conflicts appear when two or more programs compete for resources or simply cannot run together on the same PC. To eliminate software conflicts, you need to learn how to uninstall programs and delete unnecessary files.

To avoid long-lasting computer issues, make sure to take glitches seriously and do your best to fix them timely. When it comes to software-related glitches, we recommend you to use a dedicated PC optimizer like Auslogics BoostSpeed to resolve and prevent them.
