Laptop turns on and off repeatedly

HP Recommended
HP Envy Notebook Bang & Olufsen P6M52PA#AR6
Microsoft Windows 10 (64-bit)

Dear HP,


Once my laptop starts and shows desktop, it then suddenly blinking on and off repeatedly. I cannot access anything, expect I could accessed Task Manager (Ctrl+Alt+Del) and also I could access, for example, Google Chrome. So the screen is still blinking on and off, while Task Manager and Google Chrome page still there and could be used.


However, I could not access anything, eg. Control Panel etc. I think the hardware is okay, but the Windows 10 is the problem. I already access F1, F2, F8, F10 etc, from BIOS Set Up Options, System Configuration and others, but still the blinking on and off repeatedly every 1 second is not gone.


How to solve this problem?


Thank you
