The power supply unit (PSU) might fail under gaming load. Use a PSU tester or swap with a known good unit. Look for unstable voltages or sudden shutdowns during stress tests. A weak or failing PSU often causes random restarts when gaming demands high power.
Fixing Overheating
Overheating is a common cause of PC restarts during gaming. High temperatures can force your computer to shut down to protect its parts. Fixing overheating helps keep your PC stable and running smooth. Here are some easy ways to cool down your system.
Cleaning Dust And Improving Airflow
Dust builds up inside your PC and blocks airflow. This makes your system hotter. Open your case and use compressed air to blow dust from fans and vents. Check all fans to make sure they spin freely. Arrange cables neatly to allow air to move freely inside the case.
Replacing Thermal Paste
Thermal paste helps transfer heat from the CPU to its cooler. Over time, this paste dries out and loses effectiveness. Removing the old paste and applying a fresh layer improves heat transfer. Use a small amount and spread it evenly for best results.
Upgrading Cooling Solutions
Stock coolers might not be enough for heavy gaming. Consider upgrading to a better air cooler or a liquid cooling system. More powerful coolers remove heat faster and keep your PC running cooler. Check compatibility before buying to ensure a proper fit.
