What is the reason why the all in one machine can t be turned on?

There are many reasons, which should be analyzed and excluded one by one:

1. Whether the computer host and the monitor are powered on, if there is no power, turn on the power wiring switch and turn on the power supply. Then check whether the power supply of the motherboard and the main chassis is powered on normally. (There is a possibility that the power supply of the main chassis fails).

3. If it still doesn't work, check whether the graphics card is loose and plug it in and out again (wipe the gold finger).

4. If it is not solved, if there is a condition, try to change the graphics card (there may be a fault in the graphics card).

5. Check the memory, check whether the memory module is loose, and replug it (to wipe the gold finger).

The basic above simple methods can be solved, if it still doesn't work, it is recommended to find a professional maintenance unit and check the motherboard.

There may be a variety of reasons why the all-in-one machine cannot be turned on, and the following are some common problems and solutions: 1. Power supply problems: If the power supply cannot be powered normally or fails, it may cause the all-in-one machine to fail to turn on.

Try checking that the power plug and power cord are securely connected, that the power switch is turned on, and that the power light is on. 2. Display problem: If the all-in-one monitor's display cannot work properly, it may cause it to fail to turn on.

You can try to check whether hardware such as memory modules, hard drives, and graphics cards are connected securely and whether they need to be replaced or repaired. 4. Withered operating system problem: If there is a problem with the operating system of the all-in-one machine, it may not boot normally.

You can try to enter the BIOS interface or safe mode to repair the system or reinstall the operating system. If the above methods cannot solve the problem, it is recommended to contact the manufacturer or professional computer maintenance personnel for maintenance. Hopefully, the above will help you.
