My computer is black, and I m desperate for an answer

I'll give you the reason for the black screen, and you can combine it with your computer to find out the reason.

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.

- I hope it can help you, so remember to add more points!

If you have a problem with your graphics card, try changing your graphics card.

You check if your graphics card fan is stalled, this phenomenon is usually that the graphics card temperature is too high.

Check the hard disk cable, buckle the motherboard battery and put it on.

It may be that a certain part is not in good contact, probably check it, and the problem is not big.

It should be a hardware problem, it is recommended that you open the case, clean up the dust, wipe the slot (memory, graphics card), and then observe whether there is any abnormality, such as whether the heat dissipation is abnormal, the CPU, the temperature of the memory is too high, whether the hardware is damaged, and whether it has been overclocked recently?

It has nothing to do with the monitor, if the above does not solve the problem, it is recommended that you reverse the system or send it for repair ......

Haven't seen it. Can help analyze it:

There are also software issues. It's like poisoning, but I haven't seen this situation, and this is the last way to try to change the system when you can't find the reason.

Most of it is a hardware issue.

First of all, determine whether the computer is crashed, you can press the light of the keypad numlock to see if there is a reflection If it is not reflected, it is a crash You can consider core hardware problems, such as memory, CPU, graphics card, and hard disk, all of which may be broken.

But you said that after the black screen, there is a sound when you press the computer indiscriminately, which is basically not the hardware problem mentioned above.

It's a bit messy To sum up: 1: Black screen first see if the computer is dead 2 Replace the monitor line without crashing 3 It's not good to change the graphics card driver 4 It's not good to change the graphics card Try to repair the computer is mainly a replacement method. The effect of the investigation is obvious...

There will be a "forced" sound in the host"

Problem again, there is a problem with your memory, please reinsert the memory module.
