If it can be displayed, then the problem can be found on the original display.

If the computer is turned on with a beep sound, but it is a hardware failure, such as a loose memory module, a problem with the graphics card, etc. - If there is no response after the computer is turned on, not even a black screen, it is very likely that the power supply is faulty or the motherboard is faulty. - If the boot screen appears after installing new hardware or software, it may be related to the incompatibility of the new hardware or software.

You can try uninstalling or removing newly added hardware or software. Anyway, the problem of black screen on computer boot can be caused by a variety of reasons, and it needs to be troubled and dealt with according to the situation of the ju. If you can't solve the problem yourself, Jian may consult a professional or repair technical support.

In such a situation, can the computer still be saved?

This needs to be repaired pro.

Is it a question of computer or hardware.

There is a problem with the hardware.

When encountering a black screen, if there is nothing wrong with other hardware, it is a system failure, and this is the time to fix it! The easiest way to do this is to force a shutdown and restart! Here's how it works:

You force the shutdown first, and then keep holding the power button with your hand to turn on, remember not to let go of your hand, at this time you pay attention to observe whether the computer screen appears to repair the words or the like, and you can release your hand after appearing (in this process, you can be excited to hear some sounds from the computer, then it can also be repaired like this), and then you can fix your computer according to the operation! If there is still no way to do this, you can ask customer service, after-sales, or a little, basically you can solve the problem (as long as it is not a hardware problem) Don't panic in case of trouble, let's first!

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) 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, 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 elimination and substitution should be flexibly applied, and the phenomenon that occurs in time should be excluded and treated

1. If the screen is black when running a specific program, please try to uninstall the program and reinstall it, or install it in a different version.

2. Enter the safe mode, and confirm whether there is a black screen in the safe mode? If the security mode is normal, it is usually caused by software conflicts, please check whether there are any recent system optimizations and software installation operations, and you can uninstall the recently installed updates and program software through [Control Panel] - [Programs and Functions].

4. Check whether the computer has been installed with memory or other hardware? If so, please remove the additional memory and other hardware before turning on the computer to confirm.

5. If it still doesn't work, it is recommended to back up the data and try to restore or reinstall the system.

6. If you still can't solve the problem through the above methods, please bring the machine to the service center for testing.

There are many possibilities for the black screen when booting up, such as loose memory or the display is not connected to the power supply, and the specific reason has to be analyzed on the spot.
