What should I do if the hard disk rings with a black screen after the computer is turned on, and the

Reasons for the black screen of the hard disk after the computer is turned on.

1) Failure caused by the power supply of the host.

Black screen failures caused by a damaged host power supply or poor host power quality are common. For example, when you add some new equipment, 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 alarm 12 consecutive sounds, 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) Failure caused by the quality of 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. In addition, if the graphics card is connected to the monitor, it can also cause this kind of failure, up to the AT power plug in incorrectly, or even if your hard disk or optical drive data cable is reversed, it may also cause a black screen failure.

In this case, you can check the hard disk under it.

You can take out the hard drive, attach it to another computer, and copy the files.

If the hard disk has bad sectors, then it will run very slowly and have abnormal noises.

Look at whether the graphics card is loose, open the host to see if there is any abnormal phenomenon, see if the connection between the host and the display is loose, and see if the monitor has too high voltage. I think it's a display problem, because there is no "beep" sound according to what you said, which means that the system has self-tested, so it should be a connection problem

To add, you can replace your hard drive with the hard disk on another machine, and then start it again, if it can get up, it is a hard drive, and then, take your disk to that machine and try it, you can determine where it is broken.

Also, the socket of that monitor should be plugged in hard, pay attention to it Be hard My machine used to make me depressed for a long time because of this problem
