Hi, I'm currently using an ASUS G752VS, bought it back in October, 2016.
Recently I've been encountering some issues where when I play video games like Destniy 2 and GTA 5, the computer will freeze my screen for couple seconds while the in game audio is still playing in the background, then just flashes into white, pink, brown or some other random colors; and making buzzing noise. And I can't do anything besides pressing the power button and restart. Video games that have low requirements for a PC are perfectly fine, League of Legends, Hearthstone, WoW, etc... my idle temperature is around 45-50C, when I'm gaming it usually goes from 75 to 85C, turn on V-sync helps to prevent it from spiking up to 90 or higher.
Note: The bottom part of my laptop's screen is super hot.
After restarting, the system loading screen sometimes would flashes pink for one sec
All of my drivers are updated.
