i386 C: Press enter, the system prompts you whether to overwrite the file, type y, then press enter, and restart the computer. If it doesn't work, it is recommended to reinstall the system after formatting, if it still doesn't work, then it is a hard disk problem, and it is recommended to replace it.

I've been in the computer maintenance industry for three years, and I'll talk about the reasons why the computer won't turn on.

If the power supply is damaged or the wires are not in good contact, it will not be able to provide enough power to the main unit, causing the main unit to not start. At this point, we can check the power plug.

The hardware components in the host, such as memory, graphics card, and hard disk, may fail, causing the host to fail to boot normally. At this point, we can place the hardware parts.

If the operating system fails, it may cause the console to fail to boot properly. At this time.

If the motherboard is damaged, it may also cause the console to fail to boot. At this point, we need to find a professional dimension.

The computer console cannot be turned on due to the following reasons:

The power supply may be damaged or malfunctioning such as a short circuit, causing the computer to not be able to supply power properly.

Memory modules may be loose, poorly contacted, or malfunctioning, preventing the computer from booting properly.

The hard drive may be corrupted, system files cannot be read, etc., causing the computer to not boot properly.

The motherboard may be damaged, capacitors leaking, and other problems, causing the computer to not boot properly.

The graphics card may malfunction, causing the computer to not display properly.

For example, hardware such as sound cards, network cards, and fans may malfunction, affecting the normal boot of the computer.

If the host computer does not start normally, we recommend that you try to troubleshoot the above problems and perform the following operations:

Check whether the power supply is working properly, whether there is a circuit fault, etc.

Check that the memory is installed correctly, whether there are any loose problems, and try to replace the memory module.

Check whether the hard disk can read data normally and whether there are any problems such as bad sectors.

Check the capacitors on the motherboard for leakage and other damage.

Check if the graphics card is working properly and if it needs to be replaced.

If the above methods cannot solve the problem, it is recommended to contact a professional computer repairer for further maintenance or replacement of computer accessories to restore the normal use of the computer.

1. Memory sticks.

Issue. If the computer is stuck, the host computer makes a "Dididi" sound, but the monitor is now black.

In terms of status, it is due to the memory module, which does not work properly, and the data on the hard disk cannot be transferred to the memory module. Solution: Disassemble the main chassis, remove the memory module and wipe it with alcohol, wipe the ash clean, and plug the memory module back into the motherboard.

If it still doesn't work, it may be that the memory module is damaged, and you can try again with a new one.

2. Poor contact of power cord. The main reason why most of the user's computer host suddenly can't turn on the machine is that the host often moves, and the power interface behind the host is not in good contact, so that when the host is turned on, it cannot be powered on normally, resulting in the host being unable to turn on. Workaround:

Re-fix the power connector behind the host and try to turn it on.

3. System files are missing. If the monitor shows a blue screen when it is turned on.

And a bunch of characters appear because of them. This is mainly due to the loss of important system files of the computer due to irregular operation when using the computer. Workaround:

Press "F8" when booting up, and select "Last Correct Configuration". If it doesn't work, you can restore the system with one click.

4. System poisoning. Some virus programs can affect the computer system.

Important files are corrupted, and the operation of these files is read incorrectly, and there is a blue screen, black screen, and garbled characters when the computer is turned on.

situation. Solution: Use anti-virus software to kill the virus, or reinstall the system directly.

Install computer protection software immediately after reinstallation to prevent secondary poisoning.

5. The motherboard is burned out. In the summer, many friends often forget to turn off the computer after using the computer, resulting in the computer staying in working condition for a long time. After a long time, the temperature of the motherboard is too high, which causes the computer motherboard to short-circuit and burn out, and it will keep a black screen when it is turned on.

Solution: It is recommended to take the motherboard to a computer repair shop for repair, or replace the motherboard with a new one.
