There are a few general steps that can be helpful in most scenarios. Let’s start with them. Freezes and performance drops can be caused by a sluggish system, a background process that didn’t shut down correctly, or having too many programs open simultaneously. In these instances, there are a few strategies to try out.

Restart the PC

“Have you tried turning it off and on again?” Surprisingly, this simple action can solve many issues. When your PC misbehaves, make it a habit to restart it.

Has your microphone stopped working? Are your frames per second (fps) dropping? Is your Task Manager unresponsive? Give restarting a try and see if it helps.

If your PC is completely frozen and you can’t restart it in the usual way, press and hold the power button until it turns off. Keep in mind that doing this won’t save any unsaved work, so be cautious of potential data loss.

Update Your Drivers

When was the last time you updated your drivers? It’s easy to forget, but it’s important to keep them up to date.

If you’re using a modern PC with Windows 10 or Windows 11, your computer should automatically check for driver updates. While this automated process makes life easier, sometimes a driver slips through the cracks and remains outdated.

Start by checking Windows Update -> Optional Updates. Windows will show you a list of possible driver updates. Additionally, you may need to manually search for drivers from the manufacturers of specific components, such as the graphics card, chipset (motherboard), and audio drivers.

Avoid programs that claim to update your drivers for you. Some may be decent, but more often than not, they cause problems, either through faulty updates or malware.

In some cases, you may need to roll back or uninstall a driver and then reinstall it. To do this, type “Device Manager” into the Windows search bar, select the hardware you want to address (for example, the display adapter or graphics card), navigate to the Drivers tab, and either roll back or uninstall the driver. Keep in mind that these actions can have adverse effects, so be prepared to perform a clean driver install immediately.

Utilize the Task Manager

The Task Manager in Windows provides valuable insights into your PC’s performance, such as CPU, GPU, and RAM usage, as well as the running processes and applications. Sometimes, fixing your PC is as simple as terminating resource-heavy processes.

Access the Task Manager by pressing Ctrl + Alt + Delete on your keyboard. In the Processes tab, review all running processes and identify any marked as “Not Responding.” These should be the first to close. You can also sort the processes by CPU or Memory usage to determine which ones are consuming the most resources. Select the processes you want to shut down, then click “End task” in the bottom-right corner.

Exercise caution, however. Some processes are necessary for your PC to function, and terminating them could render your PC unusable until you restart it. Moreover, closing programs in this manner may result in data loss. If you’re unsure about what to close, it’s better to leave everything as is.

Common culprits behind poor performance include browsers with numerous open tabs, games, and other resource-intensive programs. While it’s generally safe to close these, be aware that unsaved progress may be lost.

Perhaps your problems started after installing a new application. If that’s the case, using Windows System Restore can be an effective solution, provided you have restore points available. Keep in mind that reverting to an earlier restore point will also undo any changes made since that point, potentially resulting in file loss.

Here’s how to perform a system restore in Windows 10 and 11:

  1. Type “Control Panel” into the Windows Search bar.
  2. In the Control Panel, search for “Recovery” in the top-right search bar.
  3. Select “Recovery” and then open “System Restore.”
  4. In the pop-up window, click “Next” and choose a restore point to revert to. Click “Scan for affected programs.”
  5. Windows will inform you of any items or programs that will be removed if you use the selected restore point.
  6. If you still want to proceed, click “Close” -> “Next” -> “Finish” to restore your system.

Troubleshooting Freezes and Poor Performance

Your PC may freeze or struggle with performance due to various factors, such as hardware issues, software conflicts, excessive program usage, or outdated drivers. Diagnosing the problem is the key to finding a solution, but you can start with some common troubleshooting methods.

If you’ve already restarted your PC, updated your drivers, and terminated resource-heavy processes without success, here’s what you can try.

When Running Certain Apps

If a specific program or game consistently leads to PC or app freezes or slows down your computer, follow these steps:

  1. Restart the program by closing it in the Task Manager (Ctrl + Alt + Delete) and reopening it.
  2. Consider reinstalling the program. Perform a clean install by removing all related files (typically found in C:Program Files or another drive) and then reinstalling the program from scratch.
  3. Verify that you have the correct version of the program. Windows users can type “System information” into the Search bar to check their operating system version and compare it to the program requirements.
  4. Close unnecessary background processes and apps to allow the program to run smoothly. Browsers with numerous open tabs are often the culprits.
  5. Confirm whether the program is compatible with your system. Older computers may use an outdated Microsoft .NET Framework, causing issues.

Random Freezes or Poor Performance

If your PC freezes or exhibits subpar performance seemingly without any clear cause, further investigation is required. However, you can try the previously mentioned steps and consider the following additional measures.

Reset This PC

Windows 10 and 11 offer a functionality called “Reset this PC.” It allows you to start fresh without losing all your files or even perform a full format that erases everything. Resetting your PC may help resolve software-related issues.

If possible, back up your data to an external drive first. Be aware that some versions of “Reset this PC” will uninstall all your programs, potentially resulting in the loss of app settings and other files.

We recommend pursuing a full format only as a last resort. Explore the available options in Windows to determine the best approach for your situation.

Unplug External Drives and Peripherals

Something as simple as a conflict between your PC and an external drive or mouse can cause freezes. This can happen, especially when installing a new device that adds its own drivers. Try unplugging these devices one at a time to identify the cause. A good practice is to shut down your PC, disconnect any unnecessary external drives, and then restart.

Change Your Power Plan in Windows

Some demanding games require powerful PCs to run smoothly. Adjusting in-game settings can often yield significant performance improvements, especially if you don’t own a high-end PC.

Consider reducing or disabling the following settings to boost the frame rate:

  • Texture Quality and Projected Textures
  • Water Effects
  • Lighting Effects
  • Anti-Aliasing
  • Shadows
  • Ambient Occlusion
  • View Distance

If you’re using ray tracing, disabling it can greatly enhance performance in most games.

Enabling V-Sync or Adaptive Sync can help prevent screen tearing, but they may impact overall performance and frame rates. Ensure your monitor’s refresh rates align with the game settings to minimize screen tearing.

Lowering the game resolution should be a last resort. Running a game at a resolution different from your monitor’s native resolution may exacerbate screen tearing. Lowering the resolution from 4K or 1440p to 1080p may improve performance but visibly downgrade the game’s visuals. If you already own a 4K monitor, upgrading hardware is likely a better solution.

Keeping your GPU drivers up to date is crucial for optimal gaming performance. Downloading GeForce Experience (for Nvidia GPUs), AMD Software: Adrenalin Edition (for AMD cards), or Intel Arc Control (for Intel GPUs) makes driver management and performance monitoring more convenient.

Other Considerations

Most of the guidance covered above can also apply to gaming-related issues. However, several additional steps are worth mentioning:

  • Monitor CPU and GPU temperatures during gaming sessions to identify potential thermal throttling.
  • Perform a clean install of the problematic game.
  • Consider installing games on an SSD instead of an HDD for faster loading times.
  • Ensure your PC meets the game’s system requirements. Discrete graphics are necessary for running demanding AAA games on most computers.
  • Close unnecessary background processes and programs while gaming. Streaming videos or browsing the internet simultaneously taxes your PC’s resources.
  • Monitor RAM usage with the Task Manager during gaming sessions. If your PC experiences lag or performance issues, consider adding more memory.
