The last solution is to reinstall the system.

The specific steps are as follows:

1. Check whether the monitor cable is firmly and reliably inserted into the host interface, and then check whether the contact between the graphics card and the IO slot of the motherboard is good;

2. If the computer starts normally with another monitor, the original monitor may be damaged;

3. Whether the CPU fan is running;

4. You can remove all components except CPU, graphics card, and memory module, and then power on the computer. If there is a fault in the memory, there should be an alarm sound. If there is no alarm sound, then turn on the CPU and re-detect. If the computer screen is still black, it is recommended to replace the motherboard;

**Processor.

**CPU (English: Central Processing Unit Processor) is one of the main equipment of electronic computers, and the core accessories in computers. Its function is mainly to interpret computer instructions and process data in computer software.

The CPU is responsible for reading the instructions, decoding the instructions, and executing the core components of the instructions.

If the fan of the graphics card does not turn and the computer screen is black, you can try the following solutions:

1.Check the power supply: Check if the power supply is connected properly and if there is power in the finch. If there is a problem with the power supply, try replacing the power supply.

2.Check the graphics card: Check that the graphics card is installed correctly and that it is tightly connected to the motherboard. If there is a problem with your graphics card, try replacing it.

3.Check the fan: Check if the fan of the graphics card is clogged with dust, or if the mold is in the mold and needs to be replaced. If there is a problem with the fan, try replacing the fan.

4.Check the graphics card driver: Check that the graphics card driver is installed correctly and is the latest version. If there is a problem with the driver, try updating the driver.

5.Inspect the motherboard: Check the motherboard for problems, such as damaged capacitors. If there is a problem with the motherboard, try replacing the motherboard.

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

There are some users who have encountered some problems when the computer is turned on, such as saying that the fan of the graphics card does not rotate and the computer is also a black screen, which cannot be started normally.

1. The power cord of the graphics card is not plugged in

We can take the computer apart, then find the power strip of the graphics card and check itIs it loose, you can plug it in and unplug it again, and then turn it on again to see if it is normal.

2. The power supply voltage of the graphics card is insufficient, and then use a multimeter to measure whether the voltage of the power supply end of the graphics card is normal, if it is normal, then you need to repair the motherboard, if it is different, you need toRepair the graphics card,Replace a graphics card.

3. The graphics card fan has been replaced

In this case, you need to use oneA normal boot computer to test it out, change the graphics card to see if it can work normally, if it still can't be turned on on a good computer, then you can be sureIt's a matter of reading the graphics card, directly contact the graphics card manufacturer for after-sales.

After the screen goes black, press the numlock key of the keypad to see if the indicator light is reflected, if there is a reflection, the monitor is problematic, if the monitor is powered by an adapter, replace the power adapter, if the adapter and the monitor are integrated, it is recommended to send it to the maintenance station.

If the keyboard does not reflect, the host crashes, the keyboard scans for bad sectors, the driver is updated after the graphics card is replaced, and whether the graphics card needs to be powered separately.

I suggest you go to test your monitor,Two days ago, my friend's machine also encountered the same problem,At first, it was judged that it was a problem with the host,But after some investigation,I found that it has nothing to do with the host,Finally, take the monitor to test,It was found that it was a problem with the display motherboard,The problem is solved after replacement,I hope it can help you! ~

See if there is a problem with your hard disk interface and data cable, the problem encountered before is the same as this, just replace the hard disk data cable.

Your problem, I also used to be in the countryside of Jilin, the voltage was unstable, so the situation is similar to you, the TV at home is not stopped, obviously my computer is turned off, the monitor is on, I guess the voltage is unstable in your house, then buy a stabilizer handle, I bought one at that time, I tried it, it was really good, hehe.

That's all I can help, I don't know if it will help you.

According to what you say, 1 is a problem with the power supply, 2 is a problem with the motherboard, 3 is a problem with the graphics card, and I was in exactly the same situation as you before. It's just that as soon as the phone is turned on, the screen is black, and there is a problem with the graphics card, and you have to turn it on several times, or as you said

Auto jumped, you see if the CPU is too hot.。。 It is also possible to troubleshoot the computer, and if possible, take turns to try again. When you change something, the failure no longer appears, you should know what to do.
