How to solve the black screen directly when the computer starts?

You said that you have reinserted every part, CPU, graphics card, hard disk, and memory one by one. Have you tried to change to a good one?

The problem you are talking about is generally detected in the following steps:

First: Clean up the dust.

Second: Normally it's a hardware problem.

A: First change a power supply to try (this problem will occur when the power supply regulation is not enough) B: No, then change a CPU fan (the fan speed becomes smaller, so that the heat dissipation can not answer its effect).

c: Change the memory.

Normally, the above problems are more likely, but of course there are other possibilities.

D: See if the CPU is broken, such as cracks.

E: Use the software to detect whether there are bad sectors in the track of your hard disk (mainly detect the partition of the system) F: Change the data cable of the hard disk (I have encountered such problems in the maintenance) G: Change a graphics card.

H: In the end, there was no way, only the motherboard remained.

Landlord: This is a process, and trouble is the trouble point. In fact, a lot of the time it's based on experience.

It is recommended that you use the Troubleshooting Method to replace the troubleshooting.

I preliminarily judge that the problem is 1, power supply 2, motherboard 3, graphics card If several parts have been disassembled and cleaned, it should be considered as a problem with the motherboard, you can:

1。Remove the motherboard battery and discharge it for five minutes, then try again.

2。Only the motherboard and the CPU are powered on, see if there is an alarm, and if there is no alarm, it is mostly the motherboard or CPU, but the chance of the CPU being bad is very small.

3。Add memory, hard disk, and graphics card in order.

It is recommended that the memory module be reseated! Generally, the black screen at boot is a memory problem.

When the motherboard is finished, change the motherboard, but if you are an LGA775 slot, you can also see if there is a skip pin in the slot.

I also often have this situation, sometimes the system checks itself, and the screen goes black when it's over. There's no good way.,If you're a master, you can enter the DOS to adjust the program.,Those who don't understand it can only reinstall the system.。

Upstairs, there should be a problem with the system.

If poisoning is suspected, go into safe mode to kill.

The hard disk light is flashing, indicating that there is a disk read.

First of all, look at whether the motherboard lights are on, and if there is no light, turn on and off the computer to see if the power supply and CPU fan are turned, and see if they are plugged in. If you confirm that everything is good, then see if the monitor is connected, and change a good graphics card to see if it is lit up. If it still doesn't work, change the memory and plug it in repeatedly, and if it doesn't work, then change the motherboard.

Summary. 1.Turn the computer off and back on, while holding down the F8 key on the keyboard.

Even in the afternoon, it can be used.

1.Turn the computer off and back on, while holding down the F8 key on the keyboard.

2.You will then be taken to the advanced boot options, choose from the options to perform the last correct configuration and press enter.

Then I went out for a while and came back and it didn't work.

3.After the execution is completed, you can enter the computer system.

The host keyboard and mouse are lit up here.

The display doesn't light up.

What's going on. It was still usable in the afternoon.

Kiss because of a system failure.
