Step 1: Check for Overheating

One of the most common reasons for a PC to shut down unexpectedly is overheating. When your computer's internal temperature reaches a certain threshold, it may shut down to prevent damage. To check for overheating:

  1. Ensure your computer is in a well-ventilated area.
  2. Clean any dust and debris from your computer's vents and fans.
  3. Monitor your computer's temperature using a program like HWMonitor or SpeedFan.
  4. Consider investing in better cooling solutions, such as additional fans or a liquid cooling system.

Step 2: Inspect Your Power Supply

A faulty power supply can cause your computer to shut down unexpectedly. To check your power supply:

  1. Make sure all power cables are securely connected to your computer and power outlets.
  2. Inspect the power supply for any visible damage or burnt components.
  3. Test your power supply with a power supply tester or multimeter, or try using a different power supply if you have one available.
