What s the reason for the computer that keeps beating after it is turned on?

The biggest reason is that your graphics card refresh rate is turned up too high, and then your monitor is a bit old and unacceptable. The monitor screen will keep jumping. It's best to restart or shut down the machine.

Solution: Restart the host, press the F8 key on the keyboard, enter the safe mode, and after going to the safe mode desktop, my computer -- > right click -- > properties -- > hardware -- > hardware manager -- > delete the graphics card hardware. Then restart the console.

Wait until Windows is normal, the system will automatically find the graphics card, and wait for the lower right corner of the screen to appear in the normal function, then click the desktop--> right-click--> properties--> settings--> screen resolution (if the display is 17-inch flat see the discussion to adjust to 1024*768; If it is 15 inches, it is recommended to adjust it to 800*600; If it's LCD, it is recommended to adjust it to 1024*768, which is more comfortable for the eyes) and then click, advanced--> monitor--> the screen refresh rate (adjust it to about 70.) The 15-inch spherical monitor is recommended to be adjusted to 60).

There may be a problem with the graphics card, resulting in a blurred screen. After trying the first method, it is still like this, it is recommended to try a different graphics card.

If the display has been used for many years, there is a certain amount of aging. It is possible that there is a problem with the picture tube of the monitor, and the monitor cannot accept the frequency of your graphics card after it is transmitted to the monitor.

Desktop (right-click) Properties Settings Find the "Advanced" monitor Set the screen refresh rate to 75 or 85 But don't be too high, otherwise your monitor won't support it, and the screen will be black, don't look for me.

The line frequency is unstable, open the lid of the box, there is a hanging button behind it, and you can adjust it.

If you are not sure, you can go to the TV repair station, and the place where this adjustment is better will not be charged.

You degauss the computer to see if the display is magnetized, or maybe the display is malfunctioning, then you have to send it for repair.

Summary. Hello dear <>, what should I do if my laptop keeps jumping when it is turned on.

The monitor refresh rate is set too low.

When the refresh rate of the display is set to be lower than 75Hz, the screen often shakes and flickers, so adjust the refresh rate appropriately, such as setting it higher than 85Hz, and the screen shaking will generally not appear again.

The power transformer is too close to the monitor and chassis.

When the power transformer is working, it will cause large electromagnetic interference, which will cause the screen to shake. Keeping the power transformer away from the chassis and display can solve the problem.

Inferior power supplies or power supply equipment are aging.

The workmanship and materials used in many miscellaneous computer power supplies are very poor, which can easily cause the circuits of the computer to be poor or the power supply capacity can not keep up, and when the system is busy, the display will especially appear screen shaking. When the power supply equipment of the computer starts to deteriorate, it is easy to cause the same problem.

The speakers are placed too close to the monitor.
