Why does the computer display Latin?
there are two kinds of situations when the computer can't enter the system when it is turned on: the self-check is just a hardware problem, and the self-check can't enter the desktop, which is a system or driver problem.

1. The self-check can pass, but it can't enter the desktop, which is a problem of the operating system or driver:

Why can't the computer enter the desktop or blue screen of death normally after repeated restarts?

in the case of eliminating virus, it is generally because the operating system with GHOST version or other modified versions is installed, because a large number of drivers that are not suitable for your hardware devices are integrated in advance, which leads to the system's failure to correctly identify and load the necessary hardware devices.

This kind of error can be corrected by downloading and installing the operating system with the original image installation version and installing all drivers with Microsoft WHQL certification.

If you don't want to reinstall, try to boot F8 into safe mode to uninstall the incompatible drivers of the hardware devices. Attribute > There is no > Digital signature program >: Driver of Microsoft Windows Hardware Compatibility Publisher), after starting the computer to automatically identify the hardware device, reinstall the driver (WHQL) that you downloaded and has passed the Microsoft digital signature authentication. Then restart the computer again to see if there is any improvement.

Then there is software with duplicate functions in the system, which causes conflicts (for example, two or more software killers and firewalls are installed, and advertisements are blocked).

If it is confirmed that it is not a system or software problem, you need to test the hardware in the following order, first, the memory is the most likely, then the CPU, then the hard disk, and finally the graphics card, and the motherboard will basically not have a blue screen.

In addition, it is necessary to check whether the machine is overheated due to poor heat dissipation (if it is, a stronger radiator must be installed, thermal conductive silicone grease must be repainted, and a powerful fan must be replaced).

Check whether the motherboard capacitor bulges at the top (if it is, it must be replaced immediately).

It is also necessary to check whether the output voltage is unstable due to insufficient power supply of the chassis (if it is, it must be replaced immediately)

If the power-on self-test fails, it cannot be heard. It is necessary to make a preliminary judgment on the alarm sound of small horn (buzzer) in order to narrow down the scope of hardware failure. Please refer to your motherboard manual for the specific meaning of startup alarm sound.

2. If the self-check fails, there must be a hardware failure:

What should I do if I don't hear a "drip" sound after the self-check of the computer starts?

after the computer is started, the self-check fails, but there must be a hardware failure.

The following aspects should be checked:

1. The system time can't be displayed and saved correctly, which is caused by the lack of battery power on the motherboard. Replace a new motherboard battery, and press the DEL key to start the computer and reset the correct system time.

2. If yes, it is necessary to replace the motherboard capacitor in a professional computer maintenance place.

3. Unplug the memory module, wipe the golden finger with an eraser and plug it back into the memory slot.

4. Plug all the hardware and cables firmly again to avoid virtual connection.

5. Start it once with the chassis open to see if the fan is working normally, and replace it if it is not.

6. If you have a replacement power supply at hand, try replacing it.

7. Whether there is a hard disk failure will lead to a bad track, enter the BIOS to see if you can identify the hard disk.

8. There is no signal on the display, and the connection of the display part should be mainly checked. The black screen or flower screen of the display may be a problem of the graphics card or the display itself.

9. According to the alarm sound of the small horn (buzzer) of the boot chassis and your specific BIOS, make a preliminary judgment. So as to narrow down the scope of the problem. Please refer to your motherboard manual for the specific meaning of the power-on alarm sound.

1. That's all I can think of for the time being, and other components will be checked step by step by using the substitution method or the minimum loading method.
