The computer lights up red all the time, and the monitor doesn t respond10

It could be an issue with the graphics card.

It could also be an issue with the display.

A display is also commonly referred to as a monitor. A monitor is an IO device that belongs to a computer, i.e., an input and output device. It is a display tool that displays a certain electronic file on the screen through a specific transmission device and then reflects it to the human eye.

Graphics card (video

card，graphics

card) stands for display interface card, also known as display adapter, which is one of the most basic configuration and important accessories of a computer. As an important part of the computer host, the graphics card is a device for the computer to convert digital-to-analog signals, and undertakes the task of outputting and displaying graphics. The graphics card is connected to the motherboard of the computer, which converts the digital signal of the computer into an analog signal for the display of the display, and the graphics card still has image processing capabilities, which can assist the CPU to work and improve the overall running speed.

For people who are engaged in professional graphic design, graphics cards are very important.

The leading manufacturers of graphics chips for civil and military graphics cards include AMD (Supermicro Semiconductor) and NVIDIA (Nvidia). Today's TOP500 computers all contain graphics card computing cores. In scientific computing, graphics cards are referred to as display accelerator cards.

Boot sound. I don't know which aspect you're talking about. Whether it's the sound of the power being turned on or the sound of the fan turning.

The possibility of a bad CPU is not ruled out. Find a diagnostic card and try it. Let's see what went wrong.

In general, there are only two aspects to the display that does not respond. One is that the memory and graphics card are not installed properly. Most likely.

The other is that the CPU or motherboard is not working. It's unlikely, though. For others, for example, if there is a problem with the BIOS, you can reflash the BIOS for the motherboard model.

In addition, there are CPU fans that are not buckled properly can also cause similar problems. Double-check the hardware installation. In a word. Specific problems are analyzed and treated on a case-by-case basis.

Good luck in the end.

Let's check if it's a problem with the monitor.

In the memory and graphics card and hard disk and optical drive are removed to see if it is on, if it is on, it is ** out of the plug one by one, the problem is basically the problem of memory and graphics card and motherboard, basically the motherboard will not have any problems.

Not CPU

You redo the system and see.

This situation is generally a problem with the graphics card. You take the graphics card off and reinstall it. If it's an integrated graphics card.

Words. Take off the data cable of the monitor and plug it back in. If the computer failure is not Windows lag and the software is running slowly, it is generally a hardware problem, but under normal circumstances, the hardware is not easy to damage.

It's nothing more than poor contact and not well plugged in. Just remove it and reinstall it, and the general problem is solved.

The host is turned on, and the computer display screen is not lit, which means that the power is on and the power supply is good.

The fault red light can check the problem of the corresponding hardware, and each debug light corresponds to the problem of a certain hardware.

If the buzzer on the motherboard does not sound, then there is a high probability that the memory problem can be ruled out.

The rest is left with the motherboard or CPU, and the probability of CPU failure is not as large as that of the motherboard.

As for the judgment of the graphics card, look at the caps lock light of the keyboard after booting, if it can be turned on or off, it means that the computer has self-tested but does not display, and it is likely to be a problem with the graphics card.

1.Check whether the monitor and the main unit cable and connector are connected;

2.If the external monitor sees that the system has started normally, then you can check whether the switch button above the keyboard for turning off the power supply when the display is closed is normal;

3.If the external monitor and the pop-up display power-off switch are all right, the display cannot be displayed, then it may be a system problem;

The host is turned on, and then the computer display is not lit, if the fault is red, turn it off and restart, try it, unplug it, turn it off, and try to restart.

The host turned on the computer display screen is not lit, what is the problem with the deliberate failure red light, this should be repaired on the famous professional store, because they have friends who understand the computer, and they know what skirts they have, only they understand, we slowly go to the big guarantee, he will send this.

The computer is broken, and the only way to do it is to replace the motherboard.

The computer won't turn on the solution:

1.Check whether the monitor and the main unit cable and connector are connected;

2.If the external monitor sees that the system has started normally, then you can check whether the switch button above the keyboard for turning off the power supply when the display is closed is normal;

3.If the external monitor and the pop-up display power-off switch are all right, the display cannot be displayed, then it may be a system problem;

4.If you are unconditionally connected to an external monitor, please reboot it and pay attention to whether the display screen is black at the beginning of the system boot in the DOS boot state. If the screen is also black when the DOS boots, and there is no normal self-test sound, it is mostly a system failure;

The startup disk may be set up incorrectly. Solution: Modify the hard disk mode. Boot up, press F2, F10, F12 Delete (depending on the motherboard) to enter the BIOS, and set the first boot disk as a CD, floppy disk or U disk to a hard disk (harddisk);

6.HDD MBR error can be reset with DiskGenius;

7.Check whether the optical drive, USB flash drive, floppy disk, etc. are inserted, if so, you can take them out and try to turn them on;

8.Enter the BIOS, modify the hard disk mode, set different modes and try to restart to see if it can boot;

9.Press F8 to enter the mode, and select the latest correct configuration or normal startup.

10.If none of the above methods can be solved. For desktop computers, please disassemble the case, unplug the hard disk cable and reconnect it, and then see if it can be started; During the boot process, listen to and touch the hard disk with your hands to see if the rotation is normal;

11.The one-size-fits-all approach: reinstall the system.

The computer is turned on and the display does not light up. What is the reason for the constant red light?

Hello: The computer lights up red, but the monitor does not light up, which means that an oxide layer is formed on the surface of the gold finger of the memory or independent graphics card, resulting in poor contact between the memory and the memory slot, and the poor contact between the graphics card and the graphics card slot, resulting in a black screen and inability to boot. Solution:

You can turn off the power first, open the compartment, dial out the memory, use the eraser to wipe the part of the gold finger (that is, where there is a copper sheet,) back and forth a few times, and then insert it back into the memory slot (or insert it back with another memory slot), it's OK, if there is a separate graphics card, you can also use the same method to deal with the graphics card, and then insert it back into the graphics card slot, and finally install it, restart the computer and it's OK.

If you're on a desktop computer, you'll have this phenomenon where your main computer is turned off while the power switch on the monitor isn't turned off.

The green light is the running status indicator, which has no impact on the running status.

The monitor also has a switch, just press it and you're good to go.
