Overheating
One of the main reasons why a PC shuts down during gaming is overheating. When your computer’s internal components, such as the CPU or GPU, get too hot, they may automatically shut down to prevent damage.

How to fix PC overheating issues
Clean Your PC: Dust buildup can cause your PC to overheat. Make sure to regularly clean your computer, including fans and heatsinks.
Improve Airflow: Ensure that your PC has enough space around it for proper airflow. Keep it away from tight spaces or enclosed areas.
Check Your Cooling System: Make sure your cooling system is working correctly. Replace any malfunctioning fans or consider upgrading to a better cooling solution.
Monitor Temperatures: Use software like HWMonitor to keep an eye on your component temperatures while gaming. If they reach dangerously high levels, consider the solutions mentioned above.
Insufficient Power Supply
Another possible reason for your PC shutting down during games is an insufficient power supply (PSU). If your PSU cannot provide enough power to your components, it may cause your system to shut down.
How to troubleshoot insufficient power supply issues
Check Your PSU’s Wattage: Verify that your PSU has enough wattage to support all your components. You can use online calculators like OuterVision to estimate your system’s power requirements.
Replace Your PSU: If your current PSU isn’t providing enough power, consider upgrading to a higher-wattage PSU from a reputable manufacturer.

PC Hardware Issues
Faulty or improperly installed hardware components can also cause your PC to shut down during games. Here are some common hardware issues and how to fix them:
Faulty RAM: Run a memory diagnostic tool like MemTest86 to check for RAM errors. Replace any faulty modules if needed.
Loose Connections: Ensure that all internal connections, such as power cables and data cables, are securely connected.
Incompatible Components: Make sure that all your components are compatible with your motherboard and each other. Check the manufacturer’s website for compatibility information.
GPU Issues: Remove and reseat your graphics card, ensuring it is securely connected. Check for driver updates or try rolling back to a previous driver version if you suspect a driver issue.

Software Conflicts
Sometimes, software conflicts or corrupted system files can cause your PC to shut down during gaming sessions.
How to find and troubleshoot software issues
Update Your Drivers: Ensure that you have the latest drivers installed for your GPU, chipset, and other components. Visit the manufacturer’s website to download the most recent driver versions.
Scan for Malware: Run a malware scan using a reputable antivirus software to ensure no malicious software is causing the issue.
Check for Windows Updates: Keep your Windows operating system up to date by installing any available updates.
Restart PC: Boot your PC in Safe Mode and try running the game. If the issue doesn’t occur in Safe Mode, it’s likely a software conflict. Identify and uninstall any recently installed programs that could be causing the problem.
Repair System Files: Use the built-in Windows tool, System File Checker (SFC), to scan and repair corrupted system files.
Troubleshooting PC shutdown issues during gaming can be a complex process, as there are many potential causes. However, with patience and a systematic approach, you can identify the underlying problem and apply the appropriate solution.
Remember to always monitor your system temperatures, keep your PC clean, and ensure you have up-to-date drivers and software. These simple maintenance tasks can help prevent unexpected shutdowns and ensure an uninterrupted gaming experience.
