1. Open Task Manager, click File > Run new task, type ‘msconfig’ without quotes and press enter
2. Click on ‘Services’ tab, find two services named ‘Problem Reports and Solution Control Panel ‘and ‘Windows Error Reporting Service‘ (check the screenshot below), uncheck them to disable, if Windows prompts you for a restart, do it.
3. After the restart, hopefully your screen may not flash.
(NOTE: To open Task manager, Press Ctrl +Alt+Del and selct Task Manager on the screen, now you can run Msconfig command)
Hope that helps.
