My computer suddenly went black while running, ask for a solution!

The graphics card is too hot.

Turn off the monitor for a while.

What a game. settings.

It is estimated that it is caused by overclocking the resolution and refresh rate.

There are a variety of possibilities for automatic shutdown, the more common ones are:

1. Because the computer has been used for too long and the heat dissipation function of the main box is not good, the temperature of the inverted CPU and graphics card is too high, and it suddenly shuts down and restarts after playing for a long time.

2. Because of the computer virus, it is best to kill the virus first....

3. It is the least common that there is a problem with the power supply of the host, or that there is a problem with the plugging accompaniment.

Do you look at the electric fan of the main chassis and still turn?

Start Control Panel Power Options Power Usage Scheme: Take a look at this: [Always on] How does it react, [Turn off the monitor] How does it react, [Turn off the hard disk] How does it react, [System Standby] how does it react.

If it doesn't work, just restore it with one click:

A few seconds after booting in, you see a series of English prompts, you immediately press "F11" and you use "one-click restore", if it doesn't work, you have to reinstall the system.

Memory: Reseat the graphics card.

A black screen is a common phenomenon, especially on older computers or builds. There are many reasons for the failure of a computer 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, etc.

1) The monitor is powered off, or the monitor 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) Poor contact or damage to the graphics card;

4) Poor CPU contact;

5) Poor contact of memory modules;

6) Machine infection.

CIH virus, BIOS

is destructively refreshed;

7) Check the plugging and unplugging, if necessary, you can use a rubber to remove the oxide film on the gold finger;

8) If the floppy drive has a floppy disk, many times it will cause the computer to start or restart, and the computer will have a black screen and cannot enter the system. To avoid such situations, it is also possible to cancel the floppy disk boot item in the BIOS.

For the treatment of the black screen of the computer, the method of eliminating and replacing is basically adopted, and the principle should be based on replacing and eliminating the most suspicious parts first. For ordinary computer users, professional knowledge is insufficient, you can follow the following steps to analyze the cause of the failure, so that you can do it yourself.

Start by checking that the contact is good. Check whether the contact between the graphics card and the monitor is good, and whether the contact between the graphics card and the motherboard IO slot is good, and if necessary, remove it and reinstall it again to ensure that it is installed in place and in good contact.

If there is no problem with contact, it is best to try a different monitor to make sure that the monitor is fine.

If there is no problem with the monitor, 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 not, you can change the power supply to give it a try.

If the black screen still appears, take out the components installed in the computer, leaving only the CPU, graphics card, and memory sticks, 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.

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

A black screen may indicate a serious problem with your computer, and you may wish to eliminate it as described above when the black screen occurs. In the process of treatment, the method of exclusion and substitution should be flexibly applied, and the phenomenon that occurs in a timely manner should be excluded and treatedv

Why does the computer screen go black after booting up, and how to solve it.

It could be an issue with the display. I used to have a lot of this phenomenon when I was fixing monitors. Either the lamp of the display screen is aging, or the capacitor on the power board has burst out.

You said that it was only three or four months after you bought it, and that should be a problem with the display. If there is a problem with the data, it is recommended to send it for repair and let the maintenance engineer replace it after testing. If you can't figure it out yourself, you can't find it out without special instruments.

There are many reasons for black screen failure, such as software conflicts, improper driver installation, BIOS flashing errors, incorrect CMOS settings, etc. In addition, hardware damage caused by malignant viruses (such as CIH) may cause the appearance of black screen failures. When it comes to this kind of failure, if you can consider the cause of the failure, you can solve the fault and know that the other party will get twice the result with half the effort.

More than you described, it is most likely that you have a malicious program in your system, there is a Trojan horse! Because I've also encountered such a situation, or if you kill it with antivirus software first, it is estimated that you can't kill it, even if you reinstall the system, you may be hit.

The safest way is to repartition, then format, and reinstall the system, which is the safest and safest! After all, the win7 flagship is thousands of fast!

There may be a problem with the graphics card. Switch it up.
