Hi, My Asus ROG GL502VS was working fine one day, I shut it down and day after, try to start it again. I get a very strange screen with buttons and progress bar but not way to click on anything. I force shutdown it. Then try to boot it again and get an instant black screen. Nothing more(tried to let it black for a few hours). Not working anymore. The capslock key is triggered and fan are running after a few seconds. I’ve tried the following: Reset AC supplyRemove battery and discharge then try againRemove 1 then 2 RAM piece / exchange placesCan’t try on external monitor ATM. I’m afraid to have break the BIOS or anything on boot section. Anyone got an idea? :( Thank you
