PC Turns Off Randomly - Troubleshooting Steps

1. Check for Overheating

• Download HWMonitor or Core Temp to check CPU/GPU temperatures.
• If CPU is above 80°C or GPU above 85°C, clean dust from fans and vents.
• Reapply thermal paste if overheating persists.

2. Inspect Power Supply (PSU)

• If using a desktop PC, ensure the power cable is secure and the PSU fan is running.

• If shutdowns persist, replace the PSU with a higher wattage one.

3. Run a Memory (RAM) Test

• Press Win + R, type mdsched.exe, and hit Enter.
• Choose Restart now and check for problems.
• If errors appear, replace faulty RAM sticks.

4. Scan for Corrupt System Files

  bash

  CopyEdit

  sfc /scannow

  swift

  CopyEdit

  DISM /Online /Cleanup-Image /RestoreHealth

• Press Win + X, select Event Viewer.
• Look under Windows Logs > System for Critical or Error messages.

6. Update BIOS (Last Resort)

• Go to your motherboard manufacturer’s website and check for a BIOS update.
• Follow their official guide for flashing the BIOS (only if needed).

Final Recommendations

• If overheating → Clean dust, replace thermal paste
• If PSU is faulty → Replace power supply
