Computer Keeps Restarting or Shutting Down

Posted on Tuesday, July 22, 2025 by Jason G.

Is your PC shutting down or rebooting without warning — especially while gaming, editing, or just browsing?
This frustrating issue is often caused by one of the following:

✅ Common Causes:

  • 🔥 Overheating – CPU or GPU temperatures going too high
  • ⚡ Power Supply Issues – faulty PSU or unstable voltage
  • ❌ Driver Conflicts – outdated or corrupted system/device drivers
  • 🛠️ Faulty Hardware – bad RAM, GPU, or motherboard components
  • ⚙️ System Settings – improper sleep/restart triggers or startup glitches
  • 🦠 Malware – malicious software causing forced shutdowns

🧪 Quick Check Tips:

  • Use HWMonitor or Core Temp to check CPU/GPU temps
  • Run sfc /scannow in Command Prompt (Admin) to fix system files
  • Boot into Safe Mode to check if it still restarts (helps rule out drivers)
  • Test with another power supply (if possible)
  • Use Windows Memory Diagnostic to check RAM
