Hi,
Screen flickering in Windows 10 is usually caused by an incompatible app or display driver. To determine whether an app or driver is causing the problem, check to see if Task Manager flickers. Then, based on that information, you'll need to either update the app or the display driver.
Check to see if Task Manager flickers
Open Task Manager by pressing the Ctrl + Shift + Esc keys on the keyboard at the same time. If that doesn't work, right-click the Start button in the lower-left corner of your screen and then select Task Manager.
• If Task Manager doesn't flicker, an app is probably causing the problem.
• If Task Manager does flicker, a display driver is probably causing the problem.

Update your display driver
To update your display driver, you'll need to start your PC in safe mode, uninstall your current display adapter, and then check for driver updates.

1. Start your PC in safe mode, then right-click the Start button and select Device Manager.
2. Expand the Display adapters section, right-click the listed adapter, then select Uninstall device. Select the Delete the driver software for this device checkbox, then select Uninstall and restart your PC.
3. After your PC restarts, press the Windows logo key + I on your keyboard to open Settings. If that doesn't work, select the Start button and then select Settings.
4. From Settings, select Update & security > Windows Update > Check for updates.

hello. thank you for taking the time to give suggestions, it is highly appreciated. as of the moment, I tried the taskbar test and yes all of the screen flickered including the taskbar. as of starting my pc in safe mode, I was still not able to perform it as I do not have enough knowledge to do so and I'm scared that I might not be able to understand what is happening and what to do next. I'm still waiting for a chance to let someone knowledgeable to perform it. thank you!
