Why does my screen move on its own, and what happens to my phone screen moving on its own?

There can be 3 aspects to the problem.

1 is a problem with the graphics card.

2 is a problem with the display.

3 is a problem with the cable between the graphics card and the monitor.

I suspect it's a problem with the monitor.,Because some time ago my monitor at home was like what you said.,And then it didn't take long for me to play a good game and it "snapped", the monitor turned off, the standby light flashed, and the host was still running, and then I had to change a monitor.

Supplement... The landlord's 17-inch pure screen monitor,The one I broke is also a 17-inch pure screen,The old machine has a problem that is inevitable,If the landlord is the same as me,I don't like to turn off the power of the monitor after turning off the computer, then 8 9 is a display problem!

Also, the characteristics of my old monitor before it broke... The screen is a bit yellowish, and some irregular streaks are noticeable in the blue screen of starting up and turning off the computer (the screen that you welcome to use when you turn it on).

Then you ask a friend to borrow a cable and graphics card, come back and try it, the problem must be these 3 aspects.

I see you said that the system has not been replaced for 1 year, has the host not been dismantled for 1 year? If so, you can consider cleaning the dust and reinstalling the system! Troubleshoot software issues first, because sometimes it's not necessarily the hardware!

The "beep" sound is emitted by the host, which is generally the warning sound of the power supply output voltage of the host power supply (such as abnormal voltage, low three-terminal voltage regulation), or voltage regulator circuit failure;

It is estimated that the screen flash is related to the poor power supply of the host, and it is recommended that the landlord borrow a host power supply to try.

Graphics card issues! 1: Wipe the gold finger of the graphics card.

2: Lift the lid of the case! Blow the electric fan (bedside fan) at the graphics card! Solve your problem!

It may be that the number of screens on the display screen is too low, and there is more time, so it's time to take it for maintenance.

If you are using a Huawei phone, the touch screen will automatically jump and touch the screen automatically, and you can do the following methods:

1.If the problem of random jumping and ghost hands occurs only when charging with a third-party charging device, it may be caused by the unstable power supply voltage, or it may be due to the interference of the charging signal on the touch screen signal, resulting in the floating of the touch screen reporting point. It is caused by the interference of external factors, please use the standard charger and data cable to try to charge first, if there is no problem, it may be a problem with the third-party charging equipment; It is recommended that you use the original charger in scenarios where you need to charge and use touch control, and you can remove the protective case to improve the touch experience.
