Random System Reboots Without Error Logs?

1. Disable Auto-Restart on Failure

Press Win + R → type sysdm.cpl → Enter.

Go to Advanced tab → Click Startup and Recovery > Settings.

Uncheck Automatically restart → Click OK.

2. Check for Overheating

Download and run HWMonitor or CoreTemp.

Check CPU/GPU temperatures under load — anything over 85–90°C could cause shutdowns.

Clean fans, reseat thermal paste, and ensure good airflow.

3. Check Event Viewer Logs

Press Win + X → Select Event Viewer.

Go to Windows Logs > System.

Look for Event ID 41 - Kernel-Power or any critical errors around reboot time.

4. Test RAM

Open Start → Search Windows Memory Diagnostic → Restart and scan.

For deeper tests, use MemTest86 on USB boot.

Inspect the Power Supply

5. Try another known-working PSU (especially if reboots happen under heavy load).

If using surge protectors or extension cords, plug directly into wall outlet.
