PC Crashes While Gaming: 7 Possible Causes and Fixes

Is there anything more frustrating than getting fully immersed in your favorite game only to have your PC suddenly crash to desktop without warning? PC gaming crashes can happen for a variety of reasons, from overheating components to buggy software. When faced with these issues, it‘s important to have a solid troubleshooting plan to properly diagnose the problem and implement the right solution.

In this post, we‘ll cover the most common causes of PC crashes while gaming along with step-by-step instructions and fixes for each one. By the end, you‘ll be armed with the knowledge to tackle any unexpected game crashes that come your way. Let‘s dive in!

Reason 1: Overheating

One of the most frequent causes of gaming crashes is simple overheating. When your PC‘s components get too hot, they can start experiencing glitches, freezes, and crashes. Gaming is especially taxing on the CPU and GPU, causing them to heat up more than during regular PC usage.

Some telltale symptoms of an overheating PC include:

• PC shutting down on its own
• Sudden slowdowns and choppy framerates
• Crashes or BSODs (Blue Screens of Death)
• Hardware failure warnings

To check the temperatures of your CPU and GPU:

1. Download a hardware monitoring tool like Core Temp, HWMonitor or MSI Afterburner
2. Launch the tool while running a demanding game
3. Alt+Tab out of the game to view current temps
4. Look for temps at or exceeding 90°C (194°F) on the CPU or 85°C (185°F) on the GPU, which can indicate an overheating issue

If you‘ve identified an overheating problem, here are some solutions to cool things down:

• Ensure your PC has adequate ventilation with good airflow from the intakes to the exhaust. Make sure no vents are blocked or obstructed.
• Clean out the dust and debris that has collected on fans and heatsinks using a can of compressed air. Built-up dust can greatly reduce heat dissipation efficiency.
• If you‘re comfortable opening up your PC, try applying fresh thermal paste between the CPU and GPU and their respective heatsinks. The thermal paste can dry up and lose effectiveness over time.
• Consider adding a couple more intake or exhaust case fans to improve overall airflow. A closed-loop liquid CPU cooler is also a good upgrade over a basic air cooler.

Reason 2: Driver Issues

Another common culprit behind game crashes is outdated or corrupted device drivers, especially graphics drivers. Your GPU drivers are what allow your graphics card to communicate effectively with Windows and your games. If the drivers are out of date, missing important optimizations, or corrupted, they can result in crashes and instability.

The solution is to identify your GPU manufacturer (Nvidia, AMD or Intel) and perform a clean install of the latest graphics drivers:

1. Uninstall your current graphics drivers completely using Display Driver Uninstaller or the "clean install" option provided in the driver installer.
2. Download the latest driver package directly from the manufacturer‘s website:
   Nvidia: https://www.nvidia.com/en-us/geforce/drivers/
   AMD: https://www.amd.com/en/support
   Intel: https://downloadcenter.intel.com/product/80939/Graphics
3. Run the driver installer and reboot your PC when finished.
4. Launch your game again to see if the crashes persist.

Sometimes, due to driver optimizations still in progress or certain unforeseen bugs, the latest graphics driver can actually introduce new instability rather than fixing it. In this case, you may want to roll back to the previous driver version you had installed when things were working properly.

To do this:

1. Open up Device Manager
2. Expand Display adapters and right-click on your GPU
3. Choose Properties and go to the Driver tab
4. Click Roll Back Driver and follow the prompts
5. Restart your PC and test for stability again

Reason 3: Hardware Failure

If your PC is crashing during gaming no matter what troubleshooting you‘ve tried so far, you may be dealing with a hardware failure. Some components in your PC endure a lot of stress and have a limited lifespan that can end in sudden crashes and instability.

The most likely hardware failure points are:

• RAM – Random Access Memory is the memory that processes and games utilize to store data they are actively using. Faulty or dying RAM can result in memory errors, crashes, freezes and BSODs.
• Power Supply – Your power supply unit (PSU) provides power to every component in your PC. If it starts failing, your PC may crash or shut down during gaming when it tries to draw more wattage than the PSU can handle.
• Hard Drive/SSD – As your storage devices get older, they can start to fail, causing crashes when your games attempt to load data and textures from a bad drive sector. An unexpected shutdown or crash can also corrupt your drive.

To diagnose each of these potential hardware failures:

RAM

• Run a memory testing tool like Windows Memory Diagnostic or MemTest86 to scan your RAM for errors
• Try reseating your RAM sticks in their DIMM slots or test one stick at a time to isolate the faulty module
• Replace any bad RAM sticks

Power Supply

• Use a PSU monitoring tool like HWiNFO to check your voltage rails
• Make sure your PSU provides enough total wattage for your system‘s maximum power draw
• Upgrade to a higher wattage PSU from a reputable brand if needed

Hard Drive/SSD

• Check your drive‘s health status and SMART data attributes using CrystalDiskInfo
• Run a disk check and repair any corrupted sectors
• Back up your important data and replace any dying drives

Reason 4: Unstable Overclocks

Overclocking involves manually raising the clock speeds and voltages of your PC components like the CPU, GPU and RAM past their stock values to gain extra performance. While overclocking can give you more frames and faster speeds, pushing your hardware beyond its rated specifications also comes with some major stability risks.

An overclocked component generates more heat and requires more power to operate outside its safety limits. Even if you follow generally safe overclocking practices, you may still encounter crashes, freezes, and other issues, especially in games that drive your hardware to 100% utilization.

To diagnose stability issues related to an overclock:

1. Run stress testing tools that will max out your CPU, GPU, and RAM like Prime95, Furmark, and Memtest86
2. Monitor your temperatures and voltages to ensure they stay within acceptable ranges under full load
3. Look for any crashes, freezes, BSODs or visual artifacting during stress testing
4. If instability is found, incrementally dial back your overclock until you regain stability
5. As a last resort, restore your BIOS to default settings and run everything at stock speeds again

Reason 5: Software Issues

Game crashes aren‘t always due to hardware problems. Bugs or unintended glitches in a game‘s programming code can also lead to crashes, as can issues with conflicting background software or services on your PC.

Some common software-related issues that can cause game crashes include:

• Game bugs and instability due to unoptimized code or insufficient QA testing
• Conflicts with other programs running in the background like RGB software, video capture tools, overlays, etc.
• Corrupted game files from an interrupted download or botched installation
• Anti-cheat errors falsely flagging normal programs as cheats
• DRM (digital rights management) issues requiring an online check-in to play

Fixing software-based crashes will vary case by case, but here are some good general solutions to try:

• Verify your game‘s files through the launcher (Steam, Epic, etc.) to check for and repair any corrupted data
• Update your game to the latest version and look for any recent patches that may address crash issues
• Close any non-essential programs and services running in the background that could interfere with your game
• Disable any 3rd-party game overlays, FPS counters, or hardware monitoring software as a test
• As a last resort, fully uninstall and reinstall any games or programs that consistently crash

Advanced Troubleshooting

If you‘ve exhausted all the troubleshooting steps above and still can‘t seem to resolve your crashing issues, it‘s time to dig deeper with some advanced diagnostic tools and techniques. With these, we can uncover more details about the nature of the crash and potentially find clues that will lead to a solution.

The first place to check is Windows Event Viewer, which logs any application or system crashes and the specific errors associated with them. To find crash logs in Event Viewer:

1. Press Win+R and type "eventvwr.msc" to launch Event Viewer
2. Expand Windows Logs and click on Application
3. Look for any Error entries that occurred at the time of the crash. The Source column may show the application that crashed.
4. Double-click the Error entry to see more details and google any specific error codes listed.

For more advanced users, analyzing crash dump files can provide even more insight. Crash dumps are snapshot files created during a crash that contain raw data about the system‘s state and the cause of the crash. Special tools like WinDbg can open crash dump files and potentially pinpoint the driver, process or bug responsible for the crash. Analyzing crash dumps is beyond the scope of this guide, but there are plenty of great tutorials out there if you are interested in learning more.

Finally, don‘t forget about the wealth of troubleshooting resources and information available online that are often just a search away:

• Official game forums where developers and other players discuss known issues and post fixes
• Reddit communities dedicated to PC gaming tech support like r/techsupport and r/pcgamingtechsupport
• FAQ/Knowledge Base articles on a game‘s website listing common crash causes and solutions
• Contact the developer‘s customer support directly, as they may be able to offer specific guidance for your particular crash situation

Conclusion
