The computer has a black screen, the keyboard light does not light up, the blue screen becomes black

Immediately after booting, press f8 to the advanced option to appear in the let go, select "the latest correct configuration" enter to repair, and press f8 to enter the safe mode to restore the system or reinstall the system (if the reinstallation is also a blue screen, it is recommended to overhaul it, if you can enter the safe mode, it means that you have installed something inappropriate, uninstall all the inappropriate things before the accident, or restore the system or reinstall).

First soft and then hard, such problems are caused by software conflicts, inappropriate drivers, and system problems, you can restore the system in safe mode, or not reinstall the operating system, do not install software, patches, drivers, etc., and see if there is still a problem with booting? If you don't install drivers, patches, and software step by step, and find something that isn't suitable, don't install it.

If there is a hardware, take out the motherboard battery and put it on the charge, plug and unplug the memory, clean the graphics card, check whether there is a problem with the hard disk, and if it doesn't work, just overhaul it.

Pull out the motherboard battery and put it on a discharge.

The safe mode cannot be entered, it should be caused by hardware or system problems, it is recommended to redo the system, or it is not possible to check the hardware problem.

How to reinstall the system:

1. Make PE guidance tools.

3. PE boot start.

4. Use the image file to redo the system.

It can also enter the system when the graphics card is faulty.

Let's talk about the system first, you probably installed the system with the ghost image file. This will integrate a mismatched graphics card driver, so you need to uninstall the driver and install the correct driver. But sometimes legacy files and registry files are not cleaned and uninstalled.

In this case, you have to use the normal installation version and install it step by step.

If it's a hardware problem, the failure rate of discrete graphics cards is higher on desktops. You look to see if the capacitors on your graphics card are leaking.

Because if an individual capacitor leaks, it does not need a lot of power supply to drive when the system is not loaded with a large image processing unit. When you first turn on and the security mode, it is 256 colors, and there is no burden on the system image operation, but after entering Windows, if you set the high-resolution mode, the pressure of image calculation will increase, and the power supply will not be able to drive the graphics card circuit. This results in unresponsive and crashing phenomena.

The graphics card is broken, because when you enter the safe mode, the load on the graphics card is not large, so there is no problem, when you enter the system normally, the sudden increase in the requirements for the graphics card will make the graphics card not work! If it's a single display, you can see if there is a capacitor bulging on the graphics card, just replace it.

ATI Rockchip's graphics card bar This situation will occur after updating the driver Just use the old driver or adjust the screen resolution to the lowest If you don't update the driver, this situation will occur that the graphics card is damaged There is no way to change the graphics card.

The compatibility of the graphics card is not good, if it is an integrated graphics card, the BIOS shields the addition of a separate graphics card, and if it is a discrete graphics card, replace it directly.

Graphics card issues!! Remove the graphics card and reinstall it! If you get the drive a little bit more, there should be no problem!! Either try it without a keyboard!! Maybe there's something wrong with the keyboard interface!!

The graphics card driver is incompatible;

There is a problem with the graphics card, memory module, hard disk (if there is dust, it is not installed properly, etc.);

If it is an old machine upgrade or a new graphics card, you should consider the compatibility between the motherboard and the graphics card, and if it is a new machine, check the cheat link and power supply. Safe mode does not load the graphics driver, the computer is just a computer, not all errors it can react, or it will not have a blue screen. In terms of program, the main consideration is the matching of the driver and the system.

If you have the conditions, you can try to change the slot, change the motherboard, and change the system. If the hardware circuit is really damaged, it is too difficult to repair it yourself. Let's start with compatibility and find the problem.

There is a problem with the system, redo the system, do it with bois.

The graphics card driver is not compatible, the hardware can't keep up with the software, change it

It should be that the capacitor of the graphics card has exploded.

This happened to me during my summer vacation.

It's good to spend 10 dollars for 2 capacitors.

Is it a black screen? Nothing, just a mouse.

Take out the memory module, erase the gold finger with an eraser, then install it back and restart it.

You first turn down the refresh rate and resolution, go in and try it, if it doesn't work, then try a different driver.

Otherwise, there is a problem with the display or display.

The best way is that you don't install the graphics card driver, can you enter again and again. If it can be entered, it is estimated that there should be no problem with the hardware.

Since you can occasionally enter the system, it means that it is not a problem with the refresh rate, and it seems that there is a high possibility that there is a problem with the display or the display cable.

The black screen has a few auspicious shed solutions:

1。Try to boot the computer, after the computer brand is out, press F8, press Enter, Enter, enter the safe mode, and start advanced.

options, the last correct configuration, Enter, Enter, press to try!

2。Enter safe mode, start normally, press enter, go to the desktop, and use antivirus to kill the whole disk!

3。Use: Defender conducts a comprehensive physical examination of the computer, detects and kills the Trojan horse, and repairs the computer.

4。Unplug the graphics card and memory sticks, erase them, use a brush again, clean the slots of dust and fans, replace the memory slots, and more!

6。Turn it on again, if it still doesn't work, you need to "one-click restore" or Biyanfu "reinstall the system"!

Hope it helps

Reason 1: There are loopholes in the program, some applications are late, but the design of the program itself is flawed, and some software programs occupy too many resources when running, so they cause a blue screen.

Reason 2: When encountering a Trojan horse or virus attack, some users accidentally fall into the Trojan horse or virus during the use of the computer, which will cause a blue screen on the computer. You can use Tencent PC Manager to kill the whole thing.

Reason 3: The software installed on the computer conflicts, there are differences between the old and new versions of some applications, and when deleting the program, the accidental deletion of the code contains the dll file, which will lead to a blue screen.

Reason 4: Errors or corruption in the registry are the main reasons for the blue screen, and if the registry data is wrong or corrupted, it is likely to cause a "blue screen".

Don't forget to post a picture! Otherwise, you let everyone play guess!

Boot with the most recent configuration.
