Ladies and gentlemen, when I turn on the computer, EZ system adjustment will be displayed, and then click the startup menu, and a row of English letters will be displayed. I can't click it. What happened? This seems to be a hardware problem.

According to the BIOS information, all ports of the intermediate SATA information are empty, that is, the hard disk cannot be detected.

The startup item on the right also doesn't show other types of hard disk information, which should be a hard disk problem.

Open the chassis and check whether the data cable and power cable of the hard disk are connected correctly. The line is fine. Maybe the hard disk is broken and needs to be replaced.
