Solution1. Screen Flickering Test
Solution3. Reset Your Display Driver

First, test your computer whether the screen flickering is caused by software or not.
For Windows 11: Bring up the background program with pressing Ctrl + Shift + Esc simultaneously. Open Task Manage.
For Windows 10: Right-click your taskbar and select Task Manager. You don't actually need to use Task Manager, but you do need it open.
After turning it on, observe your screen, if the task manager interface flashes along with other content on the screen, it may be a hardware (screen, power supply unit) problem, or a driver failure. If everything on the screen is flickering except for the Task Manager interface, the problem may be due to an application.
If the Task Manager is flickering, you can follow the below steps.
If not, you can uninstall the application/software.
Move1. Check peripherals
If there is a problem with the computer, first check the hardware and peripherals, for it is more expensive and more troublesome to solve the hardware problem.
Firstly, unplug the Power Supply of the monitor and the main frame, and then plug it in again to ensure that the screen does not flicker due to loose power plugs.
Cords wear out over time, or if you have pets, they can chew on them. It is best to have a spare monitor cord to replace and test whether the screen continues to flicker/flash after replacing the new cord.
Secondly, if the flickering problem cannot be solved after changing the cable, replace the monitor. If the flickering problem disappears with a new monitor, it is recommended to replace the monitor with a new one or find its dealer for repair.
A monitor's refresh rate is of which the screen updates an image per second, measured in hertz (Hz). Basic monitors can usually only handle a 60Hz refresh rate, while more advanced monitors (usually aimed at gaming monitors) can go up to 360Hz. It could be the monitor's refresh rate is too high, causing the monitor to not keep up with the settings. So check your monitor refresh rate and set it to 60Hz or lower:
Press the Windows key + I at the same time
Enter into taskbar settings
On the display page, click Advanced Display Settings(Windows 10) or Advanced display (Windows 11)
Drop down and gradually decrease the lower refresh rates until the screen flashing stops. If the screen still flickers, revert to the monitor's recommended refresh rate.
The screen flashing problem can be caused by the graphics card driver. The computer might have an old driver or a faulty one. Let's make sure you are running the right version for your system.
If the previous method can't solve it, the problem may be in the driver.
Reinstall the Driver
