What is the problem with the HP 4421S machine’s fan temperature being too high and automatically shutting down after playing for a while? Even after heat dissipation treatment, the problem remains.

Hello, thank you for choosing HP products.

1. The automatic shutdown of the machine does not rule out system problems. It is recommended that you save important files and then restart the machine. When the HP logo appears on the machine, press F11 to restore the machine's operating system. See if that solves the problem you're experiencing.

Note: If your machine does not have a Windows operating system pre-installed when you purchase it, it is recommended that you try inserting the system installation CD to save important files and then reinstall the operating system to see if it can solve the problem you encounter. question.

2. If the machine problem persists after you reinstall the system, it is recommended that you contact the local gold medal service center for detailed testing to see if it is caused by hardware problems.
