How to repair the computer white screen quickly

The solution to the computer black screen: update the graphics card driver, check the connection cable, restore the old version of Windows, and stop the background application.

1, update the graphics card driver.

A common cause of white screen is that the driver of the graphics card is outdated or damaged. If the driver doesn't work properly, you will encounter problems when using related software and hardware.

As for the task of upgrading the driver, it can be directly handed over to professional driver software to solve it. The software will automatically update all device drivers to the latest correct version.

2. Check the connecting cable

This problem may be related to hardware. The first thing to do is to check whether all cables connected to the system are loose. This involves an HDMI or VGA cable connected to the monitor.

3. Restore the old version of Windows.

Microsoft will release new versions from time to time to improve the operating system and fix some bugs. However, sometimes, instead of improving system performance, Windows upgrade will lead to a black screen. You can try to restore the old version to solve the white screen problem.

4. Deactivate background applications

Background applications can also cause white screens. If the screen starts to blank after installing the application, try uninstalling the application. If you don't know which application has a problem, try to disable all unnecessary third-party applications with Task Manager.

Common faults of computer monitor

1, display screen

This problem is mostly caused by the graphics card. If it is a new graphics card, it may be that the quality of the card is poor or incompatible and the correct driver is not installed. If the old card has added video memory, it may be caused by the different model parameters of the newly added video memory and the original video memory.

2, the display black screen

If no signal is transmitted to the display due to the damage of the graphics card or the disconnection of the display, the indicator light of the display will keep flashing, indicating that no signal is received. If the resolution is set too high, a black screen will appear when the resolution exceeds the maximum resolution of the display, and the display will be damaged in severe cases. However, today's monitors have a protection function, and the resolution will be automatically protected if it exceeds the set value.

The screen shakes badly when the computer is turned on.

This phenomenon mostly occurs in wet weather, which is due to the moisture inside the display. To solve this problem completely, we can string the moisture-proof sand in food packaging with cotton thread, then open the back cover of the monitor and hang the moisture-proof sand on the tail of the neck of the CRT near the tube seat. In this way, even in wet weather, the above-mentioned "problems" will not appear again.
