Why do my games keep freezing?

We‘ve all been there. You‘re deeply immersed in an intense battle, about to beat your highest score, or on the verge of an epic win, when suddenly…everything freezes. Your game is completely unresponsive and you‘re left frustrated and disappointed. I feel your pain my friend! As an avid gamer myself, I know how annoying game freezes can be. But don‘t worry, we‘ll get to the bottom of why this happens and what you can do to fix it.

Game freezes occur due to a variety of factors that can disrupt the seamless execution of game code and graphics rendering. The most common culprits are overheating hardware, insufficient RAM, buggy game code, outdated drivers, malware, network issues or even failing hardware components. By understanding what exactly is going wrong under the hood and applying the right solutions, you can get back to enjoying uninterrupted gaming.

Let‘s first go over why games freeze in the first place.

What‘s Causing the Freezing?

When you launch a game, your PC or console has to perform an intricate ballet of tasks simultaneously to create the visuals, physics, audio and gameplay. Any hiccup in this process can cause temporary freezing or outright crashes to desktop. Based on my experience troubleshooting game lockups, these are the likely suspects:

Overheated Hardware

The number one cause of game freezes in my experience is overheating. Desktop PCs and laptops rely on fans and heatsinks to keep the CPU and GPU cool under heavy loads. Excessive heat buildup will cause these components to throttle down or shut off entirely to prevent permanent damage.

Gaming puts major stress on the GPU in particular, so poor airflow, clogged fans, dusty heatsinks or dried thermal paste can allow temperatures to spike, resulting in freezing. Modern GPUs like Nvidia‘s RTX cards can hit 90-100°C if cooling is inadequate!

Insufficient RAM

RAM stores all the game assets like textures, 3D models and map data needed instantly while playing. Running out of memory will cause severe lag and freezing as the game tries to grab the needed files from your slower hard drive or SSD storage.

Most modern titles require 8GB RAM at a minimum, but 16GB or higher is strongly recommended, especially if you have other programs open.

Buggy Game Code

Even well-tested triple-A games can have sections of buggy code that wreak havoc when certain conditions are met in-game. Updates and patches aim to fix these errors, but some can still slip through. Conflicts with specific hardware and drivers can also trigger crashes despite the game code itself being fine.

Outdated Drivers

The graphics drivers provided by AMD and Nvidia act as critical intermediaries that allow communication between the game and your GPU hardware. Old, generic or corrupted drivers can easily interfere with this process and cause freezing or visual artifacts. Keeping them updated is key.


Viruses, spyware and other malicious software running quietly in the background can sometimes disable security features and interfere with games enough to cause instability issues. Scan and clean up any infections for smooth sailing.

Network Connectivity

Many online multiplayer titles rely on a stable internet connection for smooth gameplay. Lag, high ping, packet loss and other network issues will manifest as freezing even if your local hardware is working fine. Speed and reliability of your home Wi-Fi or ISP impacts this.

Hardware Failures

In rare cases, actual physical defects with components like the GPU, CPU, RAM or storage can lead to freezing. This includes heat damage, capacitor aging, memory errors and more. Diagnosing this requires testing components individually to isolate the problem.

As you can see, there are a variety of factors at play, which is why accurately tracking down the cause is key before applying any fix.

Pinpointing the Culprit

Troubleshooting game lockups isn‘t always straightforward since you have to monitor several components simultaneously. Based on my experience, these are the best ways to dig deeper:

Check Temperatures

Use free system monitoring tools like CoreTemp, HWMonitor or MSI Afterburner to check the temperatures of your CPU cores and GPU while gaming. Temperatures exceeding 90°C for the CPU or 85°C for the GPU indicates overheating issues.

Monitor RAM Usage

Your RAM usage is visible in Windows Task Manager. If it‘s hitting 95% or more, you likely need more memory. 16GB is the sweet spot for most gaming rigs today.

Analyze GPU Load

Apps like GPU-Z show your graphics card‘s current usage percentage. If it‘s constantly hitting 99-100%, the heavy load could be triggering crashes.

Review Event Viewer Logs

System instability and crashes generate error reports in the Windows Event Viewer. Google the specific error codes to uncover potential causes.

Test Hardware

Purpose-built tools like Prime95 (CPU), MemTest86 (RAM), FurMark (GPU) and CrystalDiskMark (storage) stress test components to isolate failures.

Check Network Connection

Use or to test your network‘s actual speed, latency and reliability. Inconsistent performance can cause in-game freezing.

By combining data from temperature monitors, usage stats, stress testing and network analysis, you‘ll get to the bottom of what exactly is causing those game freezes in no time!

Fixes and Solutions

Alright, time for the good stuff! Based on the root cause, here are some tips to stop games from freezing up on you:

Beat the Heat

If overheating is the culprit, improving cooling is key. Here are some ways:

  • Clean dust buildup from PC fans, heatsinks and filters using compressed air.

  • Add extra case fans to enhance airflow across your components.

  • Replace old thermal paste between the CPU/GPU and heatsink with fresh paste like Arctic Silver 5. YouTube has great tutorials.

  • Undervolt your GPU using MSI Afterburner to run cooler at lower voltages.

  • Cap your in-game frame rate to your monitor‘s refresh rate to reduce GPU workload.

Give Your Rig More RAM

Upgrading your system memory provides more headroom for games:

  • Close browser tabs, apps and utilities before gaming to free up allocated RAM.

  • Install additional RAM sticks to increase total memory. 16GB DDR4 is the current sweet spot.

  • Increase the Windows page file size to allow more data to be swapped to disk instead of RAM.

Update and Reinstall Software

Software-related freezes benefit from:

  • Install the latest Nvidia or AMD graphics drivers. Avoid generic Windows drivers.

  • Try a "clean install" of GPU drivers after uninstalling old ones with Display Driver Uninstaller.

  • Keep Windows updated via Windows Update. Update DirectX and C++ runtimes too.

  • Validate game file integrity via Steam, Origin or Uplay to fix corrupted installs.

  • As a last resort, backup and reinstall the game itself if problems persist.

Resolve Network and Hardware Issues

For network or hardware-related freezing, options include:

  • Test your network speed, latency and reliability using online tools to identify issues.

  • Try playing offline to isolate problems with your ISP or router.

  • Use Ethernet over Wi-Fi for gaming if possible for lag-free connectivity.

  • Check CPU and GPU temperatures under load to identify overheating hardware.

  • Stress test components like CPU, GPU, RAM and drives to pinpoint failing hardware.

  • Update BIOS, chipset and storage drivers to improve compatibility and stability.

Prevent Future Freezing With Proactive Steps

Here are some recommendations to avoid those gaming interrupting freezes before they happen:

  • Update your Nvidia or AMD graphics drivers regularly to get optimizations and bug fixes.

  • Having 16GB or higher RAM gives you plenty of overhead for current games. Go with 32GB for future-proofing.

  • Maintain PC cooling with sufficient fans, dust removal and new yearly thermal paste application.

  • Close unused background programs before gaming to dedicate more resources to your game.

  • Use GPU utilities like MSI Afterburner to undervolt your graphics card for cooler operation.

  • Periodically scan for malware to remove viruses, spyware and other nasty stuff.

Breathe Easy and Game On!

Few things are more annoying than having your game freeze right as you‘re about to win! By understanding what‘s going wrong under the hood and applying the right fix, whether it‘s more cooling, RAM upgrades, driver updates or resolving network issues, you can get back to uninterrupted gaming. Proactive steps like dusting your PC regularly, installing the latest drivers and undervolting your GPU will also minimize freezes and let you focus on pure gaming enjoyment!
