What s the matter with my computer that keeps getting black screens?

A black screen is a common phenomenon, especially on older computers or builds. There are several reasons why a computer has a black screen.

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) The machine is infected with CIH virus, and the BIOS is refreshed destructively;

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, you can also 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 that the contact between the graphics card and the monitor is good, and that 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 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, remove 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 computer being tested), boot it up and re-test, if the 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.

Let's be specific. For example, black screen is what black screen is played. Is the black screen chassis still working.

How long does it take to light up after a black screen.

A black screen is generally a problem of hardware failure! For example, if the CPU fan is broken, the CPU temperature is too high, and the system automatically shuts down to protect the CPU. It is also possible that the memory module or graphics card is loose and causes a black screen, which can be unplugged and reinserted after the power is off.

If it still doesn't work, just see if the capacitor on the motherboard is blown out, under normal circumstances, it is flat, no bulge!

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 you open too many windows, the computer will not be able to load.

If it's turned on, it doesn't respond, it's black.

The black screen cannot be turned on, which is generally due to poor contact of memory or graphics card or memory quality or power supply problems or poor CPU contact (no sound or beep sound when booting up, more than two sounds are problematic, and a short tick is normal).

Generally to reseat the graphics card and memory card, the main thing is to clean the dust near the CPU and memory, which is easiest to do - or replace the memory or graphics card or power supply.

The capacitor on the motherboard may be bursting, see if the capacitor near your computer's CPU (the capacitor erected like a keg) is bulging, the normal should be flat, buy a few of the same model in the electronic market, and change it for a few cents.

There is a possibility that the graphics card or CPU is too hot, check the fan.

If none of the above is the problem, it's a problem with the display.

Hope it helps:

There are many reasons why a computer has a black screen, and the common ones are:

Shows poor contact of the data cable;

There is no power supply to the motherboard;

Poor graphics card contact or;

Poor CPU contact and overheating;

Poor contact of memory modules;

poor power performance;

Machine infection. CIH virus, BIOS

is destructively refreshed;

Microsoft black screen, please patch.

Most of these problems are the relationship between the memory and the graphics card, loose or poor contact, just move it or use the eraser to wipe the gold finger of the interface

There are many reasons why your computer has a black screen.

The first thing that should be considered is the system software, that is, our operating system;

secondly, in thinking about hardware;

Reinstall the operating system first, and the black screen can be solved;

If it doesn't work, it should belong to the latter, a hardware problem. You may need to update or upgrade your hardware.

Please check if your CPU fan is stalled or too slow, otherwise it will crash or burn out the CPU.

If it's a fan problem, replace a CPU fan or clean it and lubricate it. Thank you!

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

I ran into your question last time.

But there are many reasons for this.

The system is unstable.

The workaround needs to be installed from a single one.

System. This question is more numerous).

Hardware compatibility issues.

Mostly. Mainboard.

And. between other devices.

Compatibility issues.

It could also be a memory module.

problems. The blue screen issue generally does not occur).

There is also the problem of power supply, which is generally a problem of power supply.

It was the same with my computer last time.

1) First from the installation of the system still does not work.

Change to a motherboard.

Again, the problem is the same.

3) Finally, the power supply was changed.

The problem is finally solved, attention:

Generally, the problems caused by this cause are the most direct and intense.

It is recommended that you check your power supply.

Hope it solves your problem.

Workaround:

It can be solved one by one.

You can start with.

Start by installing the system.

Then start with the power supply to find the cause.

First. Medium virus is possible.

The second is that the heat dissipation is not good, the temperature is high, and inside the case, you can use Windows Optimizer to look at the temperature of the CPU and motherboard.

The third is that after your system is installed, it takes a long time to clean up a lot of junk files, such as registry information, and you need to clean up the junk files and junk software of the system frequently, you can use Windows Optimizer and 360 Security Guard.

You see if it's only for a specific page, and if it's only for a specific error, then there might be a problem with a plugin. If all web pages don't work, then:

Or change the browser: Maxthon or Firefox, and compare whether the screen is black when using other browsers. If the others are not, or MaxTho is also black, but Firefox is fine, then the browser is broken.

Try the reinstall browser feature with Super Bunny.

If all browsers go black, the only thing I can suggest is to reinstall the system.

Power offHehe, kidding.

If it's dark all of a sudden, you're looking again.

If you can't get into Windows, it's the graphics card's wire package burned.!

There are many reasons for the black screen, and you need to check the specific reason.
