  1. Check for Overheating
    • Ensure all vents are clear and fans are working.
    • Use a hardware monitor (like HWMonitor or Core Temp) to check CPU/GPU temps.
  2. Power Supply and Connections
    • Make sure the power adapter is secure and undamaged.
    • Try a different outlet or adapter if possible.
  3. RAM and Storage
    • Run Windows Memory Diagnostic (search in Start menu).
    • Reseat RAM and SSD if accessible.
  4. Event Viewer
    • Open Event Viewer (Win + X → Event Viewer).
    • Check Windows Logs > System for errors or critical events (look for “Kernel-Power” or “BugCheck”).

Useful Windows Commands for Troubleshooting

1. Check for Overheating

No direct command, but you can use third-party tools like HWMonitor/Core Temp.

2. Power Supply and Connections

No direct command; check physically.

3. RAM and Storage Diagnostics

mdsched.exe

Check Disk for Errors:

chkdsk C: /f /r

Open Event Viewer:

eventvwr.msc

List recent critical errors (PowerShell):

  2. Malware Scan
    • Run a full scan with Windows Defender or another antivirus.
  3. Check for MiniDump Files
