Why does the computer have to restart if it doesn t respond when it turns on?

According to your description, it should be a problem with the operating system, just follow 4; If it doesn't work, it may be a problem on the motherboard, first check the battery of the motherboard; Then check the memory chip, the most common failure is that the content in the EPROM is damaged or lost, and the re-flashing BIOS is invalid, and the chip can only be replaced;

Faults such as computer failure to turn on, freeze, black screen, blue screen, restart, and stuck operation can be checked according to the following items:

1. First of all. Check the power supply; 220V AC power supply (plug and socket are usually called); Then check the output voltage of the computer power supply (desktop check the fan of the power supply, notebook can listen carefully to see if the CPU and graphics card fans in the machine are rotating);

2. See if the computer can "self-test"; If you can self-test, you can generally reinstall the operating system;

3. If it is a black screen, focus on the inspection part (this is all and all the reasons for the black screen of the computer):

cpu；Mainboard; Memory; Graphics; display (desktop display); Power supply (Yes.)

output, but the supply voltage is incomplete); and the plug-in parts and connecting wires of the above-mentioned parts;

4. Check and remove viruses and reset the BIOS

Just reinstall the operating system.

Well, my monitor is the same, I used to restart the monitor once, and now I have to restart the monitor as well.

I guess it's the capacitors in the monitor that don't work.

If it's a capacitor change, I think it's better to just replace the display.

That's it, thanks for watching.

The above is purely a personal opinion, and we apologize for any inappropriateness.

It may be that your cable is not plugged in properly, unplug the cable between the main unit and the monitor and plug it back in to see if there is still such a situation.

The most common problems that the computer does not respond when it is turned on are: the power cord of the computer host is not properly connected, the monitor switch is not turned on, and the power supply of the monitor or the data cable of the monitor is not in good contact. When we find that the computer does not respond when we turn on the computer, we need to first observe whether the power indicator of the computer is on after the computer presses the boot button, when the power indicator is not on, then it is likely that there is a problem with the power supply, you can check whether the power cord of the host is connected to the external power supply well, whether there is a line failure, etc., when the computer power supply is bad, the computer will not respond when the power supply is bad, these need to do some simple elimination to confirm.

When the computer indicator light is on, the CPU fan inside the computer is running normally, then generally speaking, it can be preliminarily judged that there is no big problem with the power supply, and then we will check the monitor to see if the power indicator of the display is on, and whether the display data cable is well connected. At the same time, observe whether the computer keyboard and mouse indicators are on, generally if there is no problem with the host, the computer keyboard indicators and mouse indicators are normally on, this situation often appears on the monitor, such as the display switch is not turned on, the monitor data cable is not connected, or the display power supply is faulty.

Reasons why the computer keeps restarting and can't turn on and how to solve it:

1. If the computer presses the boot button, the signal lights will still light up, and the screen will also light up, we can be a little glad that the computer is only a problem with the software, and there is no problem with the hardware.

2. The software problem that can make the computer keep restarting may be infected with a virus, or the system file may be corrupted, and there are two direct solutions to the software problem.

3. The first solution, press the F8 key when booting up, enter the safe mode of the computer, and select "Last correct configuration". (If you are not sure when to press F8, you can press the power button and keep pressing F8 until the interface shown in the figure appears).

4. If the first method is useless, or after pressing F8, you can't enter the interface in the picture above, then the most simple and crude solution is to reinstall the system, find a system disc and reinstall it, if there is no system CD, the most thorough way is to restore the computer to factory settings, different notebooks, computers restore factory mode in different ways, do not repeat here.

Hardware problems: 1. There are many kinds of hardware problems that cause the computer to keep restarting, such as lack of power output power, high CPU temperature, cache corruption, loose graphics card, etc.

2. For hardware masters, you can disassemble the computer by yourself to find out the problem; If you're not an expert, it's best to send your computer in for repair.

This is usually the result of a problem with your computer's hardware or power supply**. Here are some of the parts and workarounds that can cause problems:

Power issues: If the power supply is insufficient or damaged, it may cause the computer to become unresponsive after turning on. You can try replacing the power supply, or check that the power cord is plugged in tightly.

Memory issues: If a memory module is loose or corrupted, it can also cause your computer to not boot properly. You can reseat the memory module to make sure it is securely installed.

Graphics card issues: If the graphics card is damaged or not installed properly, it can also cause the computer to not boot properly. You can try reinserting the graphics card and checking its connection.

Hard drive issues: If the hard drive fails, it can also cause the computer to not boot properly. You can try using a different computer or an external hard drive enclosure to test if the drive is working.

Motherboard issues: If your motherboard is damaged or malfunctioning, it can also cause your computer to not boot properly. You can try to check whether the capacitors on the motherboard are leaking or deformed, and find a professional repairer to deal with them.

When trying the above methods, please pay attention to safe operations, such as powering off, unplugging the power cord, grounding, etc. If you're not sure what the problem with your computer is or don't know how to fix it, it's a good idea to seek help from a professional professional.

There are several possibilities for this, whether it is a power issue**, a hardware failure, or a system failure. Here are some possible solutions:

Check for power supply** issues: Try replacing the power cord or replacing the power supply to see if that resolves the issue. At the same time, it is also necessary to check whether the power supply is connected correctly and whether there is any loosening phenomenon.

Check for hardware failures: Try replugging the memory, graphics card, hard disk, and other components to see if they are loose or damaged. If there is looseness, replugging and unplugging will usually solve the problem; If the hardware components are damaged, the corresponding hardware needs to be replaced.

Check for system failures: There may be a problem with the operating system that prevents it from booting. You can try to go into the BIOS settings and check if the boot items are correct. If you can't get into the BIOS, you can try resetting the CMOS battery and then try to get into the BIOS settings again.

If none of the above methods can solve the problem, it is recommended that you send your computer to a professional computer repair organization for repair.
