When my computer is turned on, there is a black screen, please teach me with a high finger!!

There are several main aspects of the problem:

1.If you use a pirated system, there is a possibility that such a problem will occur, it is recommended: use the genuine version.

2.If it doesn't affect your computer or happens occasionally, leave it alone, and restart your computer to disappear automatically.

3.If it is caused by a virus, upgrade the anti-virus software to completely disinfect the computer.

4.The hardware is mainly caused by incompatible memory modules, and the memory should be replaced if necessary.

5.system or other software, check whether the computer year, month, and day are correct.

6.If the driver is unstable, reinstall or update the driver in time. At the same time, using Optimizer, 360, and Master Lu to clean up junk files will also cause this problem.

8.If you use IE8, after patching, many netizens report that it is not very stable. The easiest solution is to switch to a different browser. For example: 360 Secure Browser, Window of the World Browser, Maxthon, etc.

9.If there is a problem with the system itself, install the official patches in time and reinstall the system if necessary.

10.If there is a problem with a certain software, the main thing here is to look at the software running at boot, use 360 and so on to check the software running on boot, and remove the software that does not need to run.

11.Software conflicts, uninstall the problematic software. (For example, if it occurs during installation or runtime, it can only be resolved if it is upgraded, patched, replaced with another version, or uninstalled.)

12.The following solution can be tried: if it doesn't work, the only way to do it is to restore or reinstall the system.

13.Trial command exclusion.

Start Run Enter cmd -- Enter, and enter the following command in the command prompt.

for %1 in (%windir%\system32\*.dll) do s %1 enter.

When you're done, underneath the input.

for %i in (%windir%\system32\*.ocx) do s %i carriage return.

If you are afraid of typing mistakes, you can copy these two commands, then right-click the mouse button after the command prompt, hit "paste", press enter, and wait patiently until the screen scrolling stops. Restart your computer.

14.Run regedit into the registry, under hkey local machine software, microsoft windows, currentversion, explorer, shellexecutehooks, there should only be one normal key, and delete the rest. [If there is another (default) leave it alone, it is usually empty.]

I come across this a lot.

This is the computer self-test process that should be generated by your last abnormal shutdown, and it is okay to let the machine self-test recover, and it is not a big deal.

Is it a blue screen, with a string of white letters. If it is a simple black screen, it means that the monitor VAI is not connected properly, check the connection between the case and the monitor.

It depends on what number the BIOS displays to help you analyze what the problem is.

There are some problems with the hardware.

Did you touch some button on the monitor?

I don't know what model your monitor is,You can turn down the display parameters set by the host a little,Such as 1024*768@70hz try,I've encountered similar problems and that's how it was solved,But it's been many years ago。

Display issues.

If other actions, such as browsing the web, do not appear.

That's the graphics card problem, reinstall the graphics card driver!

My suggestion copy:

1. Take the host to someone else's monitor, if there is a problem, it means that there is a problem with the settings in your system. If you can reinstall the system, it proves that your hardware and display are fine.

Second, it is strongly recommended that you change to another system disk, preferably with formatted C disk, if not, you will enter Win

PE enters a micro system and puts the C disk in the grid, and when it enters, don't mess with other disks. Then exit to reinstall the system.

It's not a problem with the graphics card.

Desktop properties --- screen saver - power --- off monitor tab set to always on on it.

I've dealt with this phenomenon.,It's a problem with the display.,To be precise.,It's a problem with the backlight of the display (LCD),Take it and fix it.

In your case, it should be a hardware issue:

1.Faults caused by the host power supply.

Black screen failures caused by a damaged host power supply or poor host power quality are common. For example, when some new equipment is added, 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 12 consecutive alarms, 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.Faults caused by the quality of the 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. If the fault is orange, the replacement method is the fastest solution to replace the graphics card, memory, and even the motherboard and CPU.

3.The quality of the connection between the accessories.

The main cause of black screen failure is the incorrect or loose connection between the memory, graphics card, etc., and the motherboard. Moreover, if there is a problem with the connection between the graphics card and the monitor, this kind of failure may also be caused, until the AT power supply is not plugged in correctly, and even if the hard disk or optical drive data cable is reversed, it may also cause the boot black screen failure.

3.Others, such as incorrect CMOS settings on the motherboard and incorrect clearing of CMOS jumpers on the motherboard, can cause a black screen failure, in this case, you can change the settings according to the instructions of the motherboard.

But I still think it's because the graphics card is in poor contact, or the quality is a bit wrong!
