The computer won t restart, what is the reason why the computer won t restart

Fault Symptom The motherboard of the computer is MSI 815E Pro, and the hard disk is IBM 20G. After the computer is booted up at one time, the screen displays: "Disk boot fallure, insert system disk and press enter", put it into the system floppy disk according to the prompt information, and after the floppy disk is successfully booted, type "C:"

After pressing the enter key, you can't enter the hard disk.

Turn off the power, open the chassis, check that the hard disk cable is in good contact with the IDE slot, and reboot the computer, and the screen still displays the original fault information. Press the RESET key to start the machine, press the DEL key to enter the CMOS settings main menu (Award BIOS), select the "IDF HDD Auto Detection" bar, and the hard disk will be automatically detected, but the hard disk cannot be detected. After multiple cold boots, enter the CMOS settings for automatic disk detection, but the disk cannot be detected.

Failure analysis and handling.

Phenomenally, the hard disk may be damaged, but the hard disk has been scanned during recent use and no corrupted sectors have been found, and the possibility of complete damage is not very high, and the last shutdown before it fails to boot is to exit according to the normal procedure.

Detach the hard disk and connect it to another machine, enter the CMOS settings main menu after booting up, select the "IDE HDD Auto Detection" column, detect the hard disk parameters, and enter the hard disk normally. Install the hard disk back on the original machine, and after entering the CMOS settings, the parameters of the hard disk can be automatically detected, and the normal boot is resumed.

1) The hard drive cable is in contact with the IDE slot and is loose.

2) The hard drive is indeed damaged.

3) The hard disk head does not return to the boot position when the power is turned off, and the hard disk parameters cannot be detected by using the automatic disk detection function in the CMOS settings. At this time, the hard disk can be removed and installed on another machine, and the parameters of the hard disk can be automatically detected by using the automatic detection function of the hard disk by different motherboards, so as to restore the hard disk head to the boot position, and then install it back on the original machine, so as to resume normal boot.

Resources.

Check if the data cable of the hard disk is not plugged in properly, and reinstall it. Try it.

It may be a problem with the settings, and it will be automatically restarted and canceled. Make sure there is no disease and clear the poison. Check whether the voltage of the power supply is normal. Is the CPU fan not spinning or slowing down? <

Demo model: Hua Tangerine pants for MateBook X

System version: win10 1, it may be a setting problem, and it will be automatically restarted and canceled.

2. Determine if there is a virus.

3. Check whether the voltage of the power supply is normal.

4. Is the CPU fan not rotating or slow?
