There are several reasons why the computer crashes when it is turned on:
First, determine the situation before the failure of the computer. If the computer crashes after moving, it may be that the computer is greatly shocked during the moving process, resulting in loose internal parts of the computer and poor contact, causing the computer to crash. Open the chassis and retighten the memory, graphics card and other devices.
If the computer crashes and fails to start after upgrading the bios program, it may be that the bios program upgrade fails or the upgraded bios program file is incompatible with the computer hardware. You can use the original bios program file to restore it.
If the screen prompts "disk boot failure", the system file is lost or damaged, or the hard disk partition table is damaged. Repair the system file or restore the hard disk partition table.
If the computer fails to start after the CPU overclock or upgrade, it may be caused by the CPU overclock or upgrade. Restore the CPU frequency to the normal frequency or the status before the upgrade.
Note: If the fault is not eliminated, the compatibility problem and quality problem of the hardware equipment shall be eliminated with the replacement method.
