The computer screen is black, what is the problem with the computer screen being black?

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。No more, enter the safe mode, start normally, press enter, and after you get to the desktop, you can kill the virus completely!

3。Use: 360 Security Guard, "Trojan Horse Killing": "360 System First Aid Kit", System Repair, Select All, Fix Now! Network Repair, Start Fixing!

Again: Start First Aid! After restarting, click on "File Recovery", select all, and delete the files completely!

4。If you can't do it again, unplug the graphics card and memory module, erase it, use a brush again, clean the slot dust and fan, replace the memory slot, etc.!

6。If you still can't turn it on, you need to "one-click restore" or "reinstall the system"!

7。If there is a problem with the hardware, send it for repair!

I think yours in general is a memory issue, hopefully yo

This situation may be that the graphics card is overheated, shut down for half an hour, wait for the temperature to drop down and then try to boot it, if it can support the system, it is sure that it is caused by overheating, if it can't be turned on, there is a hardware failure, if the problem still appears in safe mode, or the boot can not pass the self-test smoothly, it may be caused by hardware instability. It is recommended that you contact the computer manufacturer to troubleshoot the hardware.

If you have recently changed some hardware or hardware drivers, it is recommended to change them back to confirm the problem. Here are some general troubleshooting steps for hardware issues that you can try

1.If you have recently replaced your hardware, please replace it with a new one or a new one.

2.If you have more than one memory module, keep only one and unplug the rest.

3.Whether the heat dissipation is poor, causing the computer to overheat. If so, wait until the computer has completely cooled down before turning it on.

4.Check whether the wiring is loose and whether there is too much dust in the chassis, and fix and clean it.

5.If the power supply is insufficient, replace the high-power power supply.

6.If you are a laptop and encounter a hardware failure, it is best to contact the after-sales service for repair.

Good luck! If you have any questions, please ask. Helpful, hope.

Go fix it, there's something broken inside!

Causes and solutions for black screen on the computer:

1.Check whether the cable between the monitor and the computer is tightly installed, and it is recommended to re-plug the cable or replace the cable.

2.If the gold finger of the memory or graphics card is oxidized, it is recommended to remove the computer memory module, wipe the gold finger with an eraser and put it back.

3.The graphics card's memory is soldered, the performance of the main chip is degraded, the graphics card BIOS is out of order, and the control power supply IC is problematic.

4.Problems with the power supply, replace the power supply.

5.There is a problem with the boot circuit of the motherboard, as well as a virtual soldering problem with the IO, Nanqiao, etc., so it is recommended to repair the motherboard.

6.If you can see a black screen of English letters after booting up, it is generally the system that is broken. In this case, the system will need to be reinstalled.

After the laptop is turned on, it will automatically enter the sleep mode if it is not used for a long time, and the distinctive feature of the sleep mode is that the power button of the laptop is on or flashing. But the screen is really black.

In the case of making sure that the laptop screen is not damaged, the power button is on, but the screen is not lit, it means that there is a problem with the laptop screen cable, just disassemble the laptop (to power off the laptop before operating) and re-spine the cable or replace the cable to solve the problem.

Precautions for notebook use:

Pay attention to the thermal issues of the laptop: due to space and energy constraints, it is impossible to install a large fan like the one used in a desktop in a laptop. Part of the heat may depend on the chassis floor to dissipate, hold the cherry blossom to use the machine to maintain good ventilation conditions for the heat dissipation position, do not block the heat dissipation holes, and if the machine is through the bottom plate heat dissipation, do not place the machine on the hot poor conductor for a long time.

Laptops are afraid of dirty things: because laptops are very sophisticated, they are less resistant to dirt than desktops, and laptops are often taken to different environments to use, which is more likely to get dirty than desktops, so they need to be carefully cared for.

If your computer screen goes black, there are 5 possible reasons:

The computer is not connected to a power source. At this time, it is necessary to check whether the power cord is in good contact, whether the power switch is turned on and powered on.

The computer goes to sleep or hibernation. You can wake up your computer by moving or clicking on your mouse or keyboard, or by restarting it.

There may be a malfunction of the computer monitor. In this case, you need to check whether the connection between the computer and the monitor is loose or abnormal, or adjust the brightness and contrast settings of the monitor, or try to connect other monitors to troubleshoot.

There is a problem with the operating system or drivers. At this point, you can try to go into the security mode to see the problem, or upgrade or reinstall the monitor driver.

Computer hardware failure. For example, there is a problem with the graphics card, memory, etc. In this case, it is necessary to seek professional repair help to solve the problem.

It is recommended that after checking the specific situation, if the problem cannot be solved, you can seek professional computer repair services.

The reason why the computer screen is black :

1. The refresh rate of the display is too high.

2. The graphics card driver failed. Enter safe mode and reinstall the graphics driver.

3. The computer is infected with a virus. In safe mode, use antivirus software for antivirus operations.

4. The computer parts are not in good contact with the screen. Check that computer parts (display cables, graphics cards, etc.) are securely and reliably plugged into the host interface.

5. The speed of the hardware plus staring studio is too high.

6. When playing games, the graphics card does not support 3D acceleration, which will also cause a black screen.

7. The driver of the graphics card is old.

A computer (also known as a computer) is an electronic computer used for high-speed computing, which has been called "one of the most advanced scientific and technological inventions of the 20th century". The computer is composed of a hardware system and a software system, and has many functions such as numerical calculation, hetan logic calculation, and storage memory. Its application field has expanded from the initial military scientific research application to all fields of society, leading to technological progress on a global scale.

The motherboard is also called the motherboard. It's actually just a circuit board, and it's densely packed with all kinds of circuits. It can be said to be the nervous system of the PC, the CPU, memory, graphics card, sound card, etc. are directly installed on the motherboard, and the hard disk, floppy drive and other components also need to be connected to the motherboard through wiring.
