What model is your graphics card?

Summary. 1: Check the power supply of the computer motherboard When the computer is in use, suddenly the laptop screen is black, restart the computer first to test the running status of the computer, if it returns to normal, it may be that the computer is dead or dormant, considering that it is a power supply problem of the computer motherboard, you need to replace the motherboard power supply and reinstall the system.

If the screen is still black, the power supply is considered damaged and needs to be repaired.

Hello dear, glad to answer for you! 1. Check the power supply of the computer motherboard; 2. Check the display; 3. Check the memory module.

One: Check the power supply of the computer motherboard When the computer is in use, the laptop suddenly has a black screen, restart the computer to test the running status of the computer, if it returns to normal, it may be that the computer is dead or hibernating, considering that it is a power supply problem of the computer motherboard, you need to replace the motherboard power supply and reinstall the system. If the middle beam plexus is still black, it is considered that the power supply is damaged and needs to be repaired before it can be resolved.

Two: check whether the display wiring of the monitor is in good condition, we need to carefully check the oak, re-insert the display cable, if the computer suddenly flashes the word "no signal" after plugging in and quickly blacks out the screen, the beam stool shed is a wiring problem, and the rough file needs to be replaced.

Three: Check the memory module First of all, we need to open the main cover machine, take out the memory module, see if the surface or wax is attached to the dust, take an eraser to clean the gold finger on the surface, and then reinstall it.

1. First, check the connection line between the computer and the monitor.

Check the interface between the cable and the host graphics card, whether it is plugged in tightly, whether there is any looseness, and then check whether the interface between the cable and the display is plugged in tightly, and if possible, you can replace the cable to test whether the interface of the cable is worn and loose, resulting in intermittent black screen.

2. Check the adapter.

Some computers use VGA and other adapters, you can use a fan to blow the adapter, whether it is because the adapter has dust that causes bad contact and a black screen, and then consider whether the adapter is compatible with the computer graphics card.

3. Switch the display.

If you have two monitors at hand, you can try to change one monitor to see if it is caused by a bad screen on the monitor screen, or whether it is a problem with the monitor that causes the intermittent black screen.

4. Detect the graphics card.

Open the case, if your computer is an integrated graphics card, this step can be ignored, because the integrated graphics grip card is basically not good or bad.

If it is a discrete graphics card, unplug the graphics card, wipe the gold finger with toilet paper and then plug it in, and judge whether it is a black screen caused by poor contact of the graphics card by reinserting the graphics card.

5. Graphics card switching.

Check whether the computer is rented as a dual graphics card, if the computer has both an integrated graphics card and a discrete graphics card, unplug the discrete graphics card, connect the integrated graphics card, and determine whether the computer has an intermittent black screen caused by the discrete graphics card damage.

Brand model: Redmibook Pro 15 System: Windows 10

Reasons why the computer has an intermittent black screen and then returns:

1. First of all, you need to check whether the connection cable between the monitor and the computer is normal, it may be that the connection cable between the monitor and the computer is loose, resulting in the intermittent black screen of the computer.

2. Check whether the adapter is compatible with the computer graphics card, if the adapter is not compatible with the computer graphics card, it will also cause the computer to indirectly black screen.

3. Check whether the graphics card driver is missing or damaged, if the graphics card driver is damaged or missing, you need to uninstall the current graphics card and reinstall the graphics card driver.
