The graphics card of the computer is good, but the monitor has a blank screen for no reason, what s

There is a problem with the signal interface of the monitor, please check whether the signal interface between the display and the computer is connected, (the signal interface is connected virtually, there will be a blurred screen) or the display itself is faulty.

Try a different graphics card driver,If it doesn't work, it's estimated that the signal line is not good,Otherwise, there is a problem with the display,Find a manufacturer to repair it。

Cases are on a case-by-case basis. Remove the graphics card to view, if the display is still blurred, it is a display problem. If the monitor is displayed normally, it is a problem with the graphics card, and no matter what the problem is, you need to find a professional to repair it.

The graphics card is one of the components of the foundation of the personal computer, which converts the display information required by the computer system to drive the display.

In order to ensure that the system is free of any viruses and rogue software, the entire computer is disinfected.

Whether the machine has done a memory upgrade, unplug the memory and use alcohol and eraser to wipe the memory gold finger.

Uninstall the driver of the graphics card and install the official driver of the graphics card. If the machine is overheated, it will also cause a blurred screen, so you can clean the fan and reduce the CPU working temperature.

If there is no problem with the screen display itself, then most of the failure of the computer screen is caused by the graphics card itself.

How to repair the screen caused by graphics card failure:

1. Poor heat dissipation of the graphics card.

1. First of all, do a simple cleaning process, see if the display screen fault is solved, if it still does not return to normal, you need to remove it and clean it carefully.

2. After removing the heatsink, first remove all the silicone grease on the surface of the graphics card and the bottom of the heatsink, as well as the gap between the GPU and the PCB board, all the silicone grease must be cleaned, and then reapply the better silicone grease and reinstall the heatsink carefully.

3. If it is a high-end graphics card, it is recommended to attach a heatsink to all the video memory.

Second, the graphics card has a conflict with some applications.

This situation generally occurs when exiting some applications, and there is no response to random keystrokes after appearing, similar to a crash, and the fault can be eliminated after restarting the computer.

3. The driver version of the graphics card is incorrect.

If replacing the new driver does not solve the problem of the display screen, you should replace it with the original version of the driver. Generally speaking, the original driver is much less likely to have problems.

4. Improper overclocking of the processor.

If none of the above measures work, or increase the value of each overclocking voltage, such as the core voltage of the processor, the northbridge voltage, etc. Or reduce the frequency at which the processor runs, as there is a possibility that the display screen is blurred due to improper overclocking of the processor.

5. Video memory is damaged.

If none of the above methods can solve the problem of the display, then it is possible that the hardware of the graphics card is damaged, which is usually manifested as confusion of characters and cannot be distinguished.

Judging from the screenshots, there are many possibilities of display problems. It is recommended to try to test whether the display can be displayed normally through an external monitor to confirm the cause of the failure. At the same time, it is recommended to carry out corresponding fault detection and maintenance in the official after-sales service of the corresponding brand.

Take a look at the interface position of the display and the motherboard, and there is no problem. Take a look at the external monitor to see if it's normal, if it's normal, consider changing the screen.

Graphics card problems are generally blurred screens, splash screens, and 90% of your situation is a display problem.

There is a high probability of a problem with the display.

This situation is generally a problem with the graphics card, see if there is too much dust, wipe off the gold finger of the graphics card and then install it.
