To keep it short,
Woke up, cat on keyboard. Saw that the screen had some weird white page with some progress bar going on, something about "flashing" (I think).
I panicked and killed the ROG by holding the power button. I done goofed now I guess.
What happens now is that if I turn the laptop on the screen is black, fans are turning on just like normal. However no feedback on the screen what-so-ever. no logo, nothing happens spamming F1-F12 nor holding ESC. If I hold down the power button, the PC dies after 10 secs or so, but instantly turns itself on again. Only way to kill "permanently" is to unplug the power source and wait for the battery to die. I've googled like mad and nothing have worked so far in turn of plugging cable out, wait, hold power for 60 secs etc. the LED keys at the front displaying HW status like disk etc, does n't turn on, then again I can't recall if they worked before. so..
The video below "shows" the symtpom. Please, sorry in advance for the dirtness of the laptop.
