Please ask me about the problem that the boot display does not light up

1. Turn on the display, disconnect the signal cable, the display will display the information of no signal, then the host is powered on but not turned on, connect the signal cable, and the display has no signal information disappears. If the display is abnormal, it may be a problem with the display, and it may be that the signal reception of the display is not normal. It is recommended that you try a different monitor.

2. When the computer is turned on normally, the motherboard produces a dripping sound, and the optical drive, floppy drive, keyboard, mouse and other peripherals all react, indicating that the host starts normally, and then focuses on the memory and hard disk. The machine checks the device first when it starts, and the first thing to check is the memory, when the memory is faulty, the machine cannot output the display information, it is recommended to plug and unplug the memory. Then you can see if the hard disk is making sound and heating normally when it is turned on, and judge whether the hard disk is working normally.

3. Finally, if you only suspect your graphics card, it is also recommended to plug and unplug the graphics card and signal interface.

When the CRT gets wet, it's almost the same as driving it away in the sun, and I've been in this situation before. Otherwise, some parts are not in good contact, which needs to be checked by someone, and it should be handled very well.

I have the same problem, but I turn it on two or three times. The problem with my computer is caused by memory incompatibility. You can try.

There are many reasons for this. Poor contact of the monitor interface?

Dial the graphics card and reinstall it.

1. After booting on, regardless of whether the display can be lit or displayed normally, first press the restart button on the host again, and then we press the "numlock" key in the key, which is the digital switch switch key on the right side of the desktop keyboard.

2. If the digital locking light on the digital switch can be turned on or off normally, then it means that the computer host is generally fine, and it can basically be determined that the problem is caused by the display itself.

3. If the light can't be turned on and off normally, then it can basically mean that there is a problem with the hardware inside the computer case.

Computers are items that we often use in our lives, but recently, some users have reported that their computers can be turned on but the display is not lit, and they don't know how to solve it. It doesn't matter.,The following is a list of the most detailed ways to deal with the computer that can turn on the display and not light up.,Let's look down together.。

Here's how to fix it:

1. To use the electrostatic discharge method, unplug the power supply first, press and hold the power switch button with your hand to see if the computer returns to normal, if it still does not light up, it means that there is a fault inside the computer, and it should be eliminated one by one.

2. It depends on whether the keyboard indicator light is on, if the indicator light is on, it means that the computer is turned on normally, if it is not on, the VGA cable of the computer screen may not be plugged in or loosened and not lit, so you should unplug it out and try it again.

3. It may also be caused by the loosening of the graphics card, therefore, you must unplug the power supply first, open the chassis, remove the graphics card, clean up the dust in the trouser groove of the graphics card, and try to boot it back on, if it still doesn't work, it is said that the card is obviously broken, and you need to replace it with a new graphics card.

5. If the above methods do not work, it may be that there is a problem with the motherboard, so you should unplug the power supply first, open the chassis, then remove the motherboard battery, and jump to the CMOS jumper"colse"position, wait a few minutes, and try to return the jumper to its original position after putting the battery back in.

6. If the above methods are tried, if the pure friend is not lit, then the computer should be sent to the computer store to troubleshoot, especially the dead laptop, it is more difficult to disassemble, if there is no experience of friends, do not turn on at will, so as not to cause loss of other parts.

The above is the most detailed way to deal with the computer can turn on the display does not light up, and users in the same situation can refer to the above methods to solve it.
