My laptop Asus Vivobook S430FN suddenly got the display flickering then freezing. It seems the computer was also freezing and I couldn't turn it off, so I had to use the power button.\n\nThen I tried to turned it on, but it didn't turned on. After a few minutes I was able to turned it on but after a few minutes the same problem occured again. Every time I turn off the laptop I have to wait a few minutes before being able to turn it on again. Then it only survives for a few minutes or a few seconds.\n\nI've tried to connect it to an external tv but I got no signal (but I'm not sure if the hdmi cable works or not). The laptop is definitely never overheated, never shocked, and never dropped.
