The keyboard and mouse has no response. Then, there is a lot of fan noise, and later the screen goes black and then the system is rebooted.

It was able recover after reboot. However, after this issues happened serverseveral times, Itit cannot recover now. When power on, the fan keeps making noise, and the screen is black. There is no signal in the monitor.
