There is no response when the machine is turned on, the machine has a black screen, and it has been

You first see if the graphics card is not plugged in tightly, or if it has not been cleaned up for a long time. If it doesn't work, then your machine may be poisoned, or your hard drive capacity is not large enough, and many things run when the machine is booted, and it won't run. It is possible to unload a part of it appropriately and assemble it again after reassembling.

Most likely, it was a power failure. I've been in a similar situation, but I'm restarting automatically. See if the power supply fan is not turning, check the gold finger of the memory, clean it with an eraser, check whether the cable between the graphics card and the display is loose, and check whether the chassis is too dusty.

The yellow light flashing on the monitor --- means that the monitor has not received a signal--- check whether the connection cable is loose.

Is it repeated over and over again to turn on and turn off the power automatically--- to turn on and off automatically? I think it's poisoned.

Other possible hardware problems--- Loose hard drive cable (plugging and unplugging hard drive cable), memory module aging (plugging and unplugging memory sticks with an eraser), case temperature too high (case lid open to let the fan through).

It is recommended that you open the chassis and plug in the graphics card tightly.

Then reinstall the system (phobiavirus).

After that, see if there is a problem, if it still doesn't work, I'm afraid the hard disk is broken, and the hard disk needs to be replaced.

Check whether the gold finger of the memory and graphics card has oxidation, the humidity is very high these days! Good luck

Take it out and check whether the lower card strip is plugged in tightly, and change the power supply.

Your hard drive is broken. If you don't believe it, look at it differently.

Memory gold finger eraser with an eraser.

Is it the display with a black screen that is otherwise normal.

Hello dear. After clicking on the restart, the screen is black, and the computer can't be turned on, the brain boots up the black screen, and the hardware problem is removed, and the system needs to be redone. The first talk about the limbs first popularized science, and the computer screen went black.

A black screen is a common phenomenon, especially on older computers or builds. There are many reasons for the failure of a computer's black screen, such as a damaged monitor, a damaged motherboard, a damaged graphics card, a bad contact of the graphics card, a damaged power supply, a damaged CPU, and a high temperature of components. There are also cases where the model is artificially caused by the black screen of the computer, such as the positive verification of Microsoft China.

Redo the system first and see if redoing the system can solve the problem. If you can't, it's a bit of a hassle. If you can disassemble the machine, you can disassemble the machine by yourself, reinsert the memory, graphics card, and hard disk, and clean up the gold finger if it is a separate display.

Of course, the cool breeze with a hair dryer blows off the dust. After processing, reboot the machine, do the system, and see if it can be turned on normally. If it still doesn't work, then you can only go to the repair computer shop and find a master to repair it.
