What s going on with my boot monitor screen black?

Is the monitor powered on?

If you have a black screen on your computer, it may be due to aging hardware, a problem with the motherboard, or a virus infection.

1. There will be a lot of dust on the fan fan and other hardware of the computer, which needs to be cleaned regularly. On the desktop, simply disassemble the case cover, remove the hard disk, memory module and other hardware, wipe it, and then reinstall it. Laptops, at home, you can search for the corresponding model on the Internet to teach disassembly tutorials, and you can also clean up the dust.

Second, see if the power of the monitor is turned on, see if the monitor switch is turned on, and then see if the power indicator of your host is on.

3. Check whether there is a problem with the power supply, CPU, fan and graphics card of the computer, see if the gold finger of the graphics card and the memory is not in good contact due to oxidation, and check the CPU and his power supply module to see if the capacitors around the CPU are bursting, smell whether there is a burnt smell, if there is a smell, it is hardware damage.

4. Enter the BIOS settings when booting up, press and hold F10 on the desktop, and press and hold F2 on the laptop. Click to enter safe mode and perform a full scan to kill the virus software.

Fifth, it may be that the hardware version of the computer is too low, so the drivers of some hardware are upgraded and repaired.

6. Reinstall the computer system, it may be a bug caused by your use of a pirated system.

You can try the following things when your computer monitor screen goes black:

The first thing to do is to check whether the circuit connection of the monitor is normal, and if you have a stronger hands-on ability, you can also check whether the connection between the motherboard graphics cards is normal, and you can try to reseat the graphics card.

After checking the hardware device of the machine, if there is still a problem, you can connect it with another monitor or graphics card to see if it is a problem with your own device.

What also needs to be checked is whether the CPU fan is rotating, whether the output of the voltage can be measured through the multimeter is normal, and if there is an abnormal problem, the power supply needs to be replaced.

If it is a CPU or motherboard problem, it is basically only possible to replace the CPU and other hardware, if it is a system problem, we can make a system disk through a USB flash drive to reinstall the system for the computer, pay attention to use an empty USB flash drive to operate.

The computer boot display has a black screen, "If the mouse is visible, the system is still loading, and it can enter the desktop after it is fully loaded."

The causes of the problem are the motherboard battery failure, loose or damaged memory modules, etc. After shutting down the main machine, open the main chassis and check the motherboard battery and memory module.

When the computer monitor has a black screen and no signal, and the host computer is running normally, there may be several reasons:

Cable history problem: Check whether the connection between the computer monitor and the main unit is stable. If the connection is poor or damaged, the monitor will not be able to receive the spike signal, resulting in a black screen.

Display issues: If your computer is working but the monitor isn't responding, there may be a problem with the monitor itself. Try connecting the monitor to another computer for testing, and if it doesn't work as well, the monitor may be malfunctioning.

Graphics card problem: The graphics card converts the image signal generated by the computer host into a signal that can be recognized by the display, and if there is a problem with the graphics card, it will cause the display to fail to display normally. You can try to reseat the graphics card, or replace the graphics card to resolve the issue.
