Check system temperatures:

1. Download and run hardware monitoring software
2. Monitor CPU and GPU temperatures under load
3. Clean dust from fans and heat sinks if temperatures exceed 80°C
4. Verify all system fans are functioning

Test power supply stability:

1. Run stress test using built-in tools:

sfc /scannow

Corrupted system files can prevent proper shutdown processes:
