The computer is stuck with a black screen. It should have something to do with the hardware of the computer, such as when you turn it on. When an application is applied, the CPU needs to be processed. At this time, the voltage is relatively high, and if there is a problem with the power of the power supply, it may lead to a black screen and a problem with the graphics card.

There are many factors for this, the first is that your machine has not cleaned up the dust for a long time, it is recommended to unplug the memory graphics card and blow the dust off the memory. Graphics card copper plate with an eraser down on the installation to see if it's okay not yet it's your computer

Viruses, system crashes, etc

It may be that the CPU and memory usage is high when the computer is running.

And the low hardware configuration of the computer will make the computer stuck, long buffering time, and black screen.

When the computer system reacts, it resumes normal operation.

Right-click on an empty space on the desktop and select "Personalize" from the menu. After opening the personalization dialog, find and tap "Screen Saver" to enter the screen saver settings dialog box. Set the screen saver to "None", find and click "Change Power Settings" to enter the power settings dialog box.

Find and click "Change Plan" to enter the change settings dialog box. Mouse click and pull down the triangle, select "Never", and finally "Save Changes" to exit.

The best solution is to reinstall the system.

The temporary solution is: antivirus, clean up the computer junk, delete unused software, and unwanted software. Deal with it with 360 Guard!

It is recommended that you use HDTune to check the health of the hard disk, if there is a large number of yellow bars or red bars in 05 C4 C5, it means that there is a problem with the hard disk, and if there is data in C7, it may also cause lag.

Answer, this situation is basically due to the integrated module on the voltage regulator circuit inside the computer, the internal thermal breakdown is caused, you need to go to the professional store to test it, answer for reference, thank you.

A black screen is a common phenomenon, especially on older computers or builds.

There are many reasons for the failure of a computer's black screen, such as a damaged monitor, a damaged motherboard, a damaged graphics card, a poor contact of the graphics card, a damaged power supply, a damaged CPU, and a high temperature of the components. There are also artificially caused by the black screen of the computer, such as the genuine verification of Microsoft China.

Restart the machine, press the F8 key, see if you can enter safe mode, it will be easy to do, and the system can be restored.

If it doesn't work, start it with a DOS floppy disk, see if it can enter the hard disk, and if it can enter, it depends on whether you have done a ghost clone backup, and some machines are done at the factory, and if you can't get in, the format will digest the hard disk and reinstall the system. Stupid.

Under what circumstances is the black screen for a few seconds,Play the game or do nothing,Is this frequency high?,Generally speaking, on your branch phenomenon,The main suspicion is the graphics card and power supply,You can determine the law of the problem in going to the master of the installation shop Kaizhou to solve it for you,Or you take it and can't find the problem, you have to take it home It's very troublesome,You belong to a high configuration,Replace things to test,The same may be more difficult to find,Find a replacement staring and shielding may not necessarily find the problem。

Now that you know it's not about the graphics card. Then you should consider swapping out the monitor!

Or, a problem with the decompressor. If you have a decompressor behind your monitor, damage to the decompressor can cause the screen to go black frequently!

A small battery on the motherboard that is low seems to cause a black screen as well!

You test if it's about your monitor.,Borrow a monitor from a friend and install it on your computer.,See if the screen will go black.。。。 Or you can change the data cable.

1. First of all, check whether the contact is good. You can check whether the contact between the graphics card and the display is good, and whether the contact between the graphics card and the IO slot of the motherboard is good. If necessary, remove it and reinstall it again to make sure it is in place and in good contact.

2. If there is no problem with the contact, it is best to try another monitor to make sure that there is no problem with the monitor.

3. If there is no problem with the display, check whether the CPU fan is running, if it is running, use a multimeter to measure whether the voltage output is normal to 12V, 15V, if it is not normal, you can change a power supply to give it a try.

4. If the black screen still appears, take out the components installed in the computer, leaving only the CPU, graphics card, and memory module, and the cause of the fault can be limited to the CPU, motherboard, and memory. Generally, if there is a fault in the memory, there should be an alarm sound. If the memory fault is ruled out, only the CPU and the motherboard are left.

5. Change a normal CPU (should be compatible with the tested computer), boot and re-test, if the black screen still appears, you can only change a motherboard, and the problem should also appear on the motherboard.

When the computer is running, it suddenly turns into a black screen, and after a few seconds it is fine again, what is going on.

1. First of all, check whether the contact is good. You can check whether the contact between the graphics card and the display is good, and whether the contact between the graphics card and the IO slot of the motherboard is good. If necessary, remove it and reinstall it again to make sure it is in place and in good contact.

The computer will suddenly get stuck if it doesn't move, then the screen will go black, and it will be rigid again in a few seconds. Sometimes it's a full-screen jump! The system has been reloaded! The driver has been reloaded! The graphics card, the memory module are all down. Reloaded. Neither.

This problem came up suddenly. It's good to play League of Legends. Suddenly the fps becomes 0. Stuck and completely immobile. And then the question arises.

What about the motherboard? Haven't been tested.

The motherboard doesn't know how to check it.

If you are looking for a computer repair shop, you can first check the cost of the test online. Don't be fooled.

Black screen glitch caused by host computer failure:

1) Failure caused by the power supply of the host.

Black screen failures caused by a damaged host power supply or poor host power quality are common. For example, when you add some new equipment, the display has a black screen failure, after eliminating the quality and compatibility problems of accessories, the quality of the power supply is not good, and the lack of power is the main cause of the failure, at this time, you may also hear the horn in the machine alarm 12 consecutive sounds, replacing the high-power and high-quality power supply is the best solution to this kind of failure. In addition, some motherboards have ATX dual power connectors, and the wrong choice of jumper settings can also cause this kind of failure.

2) Failure caused by the quality of accessories.

Poor quality or damage to computer accessories is the main cause of black screen failure of the monitor. For example, problems with the motherboard (and the CMOS of the motherboard), memory, graphics card, etc., may definitely cause a black screen failure. Its fault performance is like the display light is orange, at this time, replace the graphics card, memory, and even the motherboard, CPU try, is the fastest solution.

The reasons for the black screen are as follows:

1. The display is powered off, or the display data cable is in poor contact. In addition, the computer has been used for a long time, and the power cord of the monitor is easy to oxidize and break.

2. There is no power supply to the motherboard.

3. The graphics card is in poor contact or damaged.

4. Poor CPU contact.

5. Poor contact of memory modules.

6. The machine is infected with CIH virus, and the BIOS is destructively refreshed.
