Why Does My PC Restart When I Play Games? And Why Do Cats Always Sit on Keyboards?

When you’re deep into an intense gaming session, the last thing you want is for your PC to suddenly restart. This frustrating issue can stem from a variety of causes, ranging from hardware problems to software conflicts. Let’s dive into the possible reasons and explore some solutions.

1. Overheating

One of the most common reasons for a PC restarting during gaming is overheating. Gaming pushes your hardware to its limits, causing components like the CPU and GPU to generate a lot of heat. If your cooling system isn’t up to par, the temperature can rise to dangerous levels, triggering an automatic shutdown to prevent damage.

Solution: Ensure your PC has adequate cooling. Clean out dust from fans and heatsinks, consider upgrading your cooling system, and monitor temperatures using software like HWMonitor.

2. Power Supply Issues

A failing or insufficient power supply unit (PSU) can cause your PC to restart under heavy load. Gaming demands a lot of power, and if your PSU can’t deliver, your system might shut down to protect itself.

Solution: Check if your PSU is powerful enough for your components. Consider upgrading to a higher wattage PSU if necessary.

3. Driver Problems

Outdated or corrupted drivers, especially for your GPU, can cause instability during gaming. This can lead to crashes or restarts.

Solution: Regularly update your drivers. Visit the manufacturer’s website for the latest versions.

4. Software Conflicts

Background applications or conflicting software can interfere with your game, causing your system to restart.

Solution: Close unnecessary applications before gaming. Consider performing a clean boot to identify any conflicting software.

5. Hardware Failures

Faulty hardware components, such as a failing GPU or RAM, can cause your PC to restart during gaming.

Solution: Run diagnostic tools to check for hardware issues. Replace any faulty components.

6. Overclocking

Overclocking your CPU or GPU can lead to instability, especially if not done correctly. This can cause your system to restart during demanding tasks like gaming.

Solution: If you’ve overclocked your components, try reverting to stock speeds to see if the issue persists.

7. Operating System Issues

A corrupted or outdated operating system can cause various problems, including unexpected restarts.

Solution: Ensure your OS is up to date. Consider performing a system restore or reinstalling the OS if necessary.

8. Malware

Malware can cause a wide range of issues, including system instability and restarts.

Solution: Run a thorough malware scan using reputable antivirus software.

9. Insufficient RAM

Running out of RAM during gaming can cause your system to become unstable and restart.

Solution: Consider upgrading your RAM if you frequently run out of memory.

10. Game-Specific Issues

Some games may have bugs or compatibility issues that cause your system to restart.

Solution: Check for game updates or patches. Visit the game’s forums or support pages for any known issues.
